Last War Survival Mason Guide: Skills, Gear, and Best Use

Mason is an SSR Tank Attack hero in Last War Survival who specializes in Physical Damage and monster-focused PvE. He is easy to develop compared with premium UR attackers, works naturally alongside early Tank heroes, and later gains an SSR-to-UR promotion path.

His strongest early role is supporting Tank-heavy monster teams while contributing his own back-row damage. Mason is much less specialized for competitive PvP, so the correct skill priority depends heavily on whether you are building him for general progression or the PvE content where he performs best.

This Last War Mason guide focuses on the questions players are actually searching for: Mason skill priority, UR Mason skill priority, gear order, Tank formations, Season 1 promotion preparation, and whether continued investment makes sense.

Best Mason Skill Priority

There is no single Mason skill order that is best for every battle. His monster passive can be extremely valuable in PvE but contributes far less in normal player-versus-player combat.

The main decision is therefore simple: if Mason is being kept because of his PvE specialization, invest more aggressively in his monster-damage effect. If you are still using him everywhere because he is one of your most developed heroes, his universally active damage skills provide a safer return.

Mason Overview

Mason benefits from the Tank Center together with other Tank heroes. Upgrading the building improves Tank Hero March Size, HP, Attack, and Defense, so its value increases if Tank remains one of your important formations.

Is Mason a Frontline or Back-Row Hero?

For normal formations, Mason belongs in the back row. He has the Attack specialty, and keeping him behind dedicated defenders gives him more time to use his damage skills.

There is one useful exception. In specialized boss or monster formations, a sufficiently durable Mason can sometimes move into the front row beside a defender so that three stronger Tank heroes occupy the back row and benefit from his monster-damage support. Only use that setup when Mason can actually survive the fight.

How Long Does Mason Stay Useful?

Mason usually has three distinct phases:

He does not need to remain in your main PvP formation forever to justify the resources used on him. Mason’s monster specialization can give him a separate job after heroes such as Kimberly and Stetmann become stronger general-purpose damage options.

SSR Mason Skills

Quick Reload

Quick Reload is Mason’s Auto Attack. Its documented base version attacks with a Minigun and deals Physical Damage equal to 69.89% of Mason’s Attack with a 1.10-second cooldown.

Quick Reload is valuable because it works regardless of enemy type. That makes it a strong early priority when Mason is being used in campaign progression, Arena, monsters, and other mixed content rather than as a dedicated PvE specialist.

Zombie Purge

Zombie Purge is Mason’s defining SSR PvE skill. Its documented base effect increases the damage dealt to monsters by Tank heroes positioned in the back row by 8.50%.

Zombie Purge matters because it can improve more than Mason’s own damage. If Kimberly, Stetmann, or another Tank attacker is also in the back row, the value of the passive is multiplied across several important damage dealers.

Its limitation is equally important: the effect is tied to monsters. It should therefore move down your priority list when Mason is being used mainly in Arena, Enemy Buster, or other standard PvP.

Fire Cover

Fire Cover is Mason’s main Tactics attack. Its documented base version deals Physical Damage equal to 568.69% of Mason’s Attack and uses a longer cooldown than his regular Auto Attack.

Fire Cover is the better skill to emphasize when you want Mason’s personal burst damage rather than only the squad-wide value of Zombie Purge. It also scales directly with his Attack, making offensive gear especially useful.

Super Sensing

Super Sensing is Mason’s Expertise skill and increases his personal HP, Attack, and Defense by 10% in his SSR form.

This is a useful all-purpose upgrade because its stats remain relevant in both PvE and PvP. It still does not change Mason’s core identity: most players use him for damage rather than as a frontline defender.

UR Mason Skill Priority

Mason’s skills reset to Level 1 when he is promoted to UR, and the promotion introduces a changed UR skill set. Previously spent Skill Medals are refunded, allowing you to choose a new priority instead of being locked into the SSR allocation.

Current English-language references use slightly different labels for the promoted skills depending on client version and localization. Match them by effect if the names on your hero screen differ.

Should You Max Mason’s Skills Before UR Promotion?

You do not need to leave SSR Mason weak simply because a promotion is coming. Skill Medals spent before promotion are refunded under the Hero Promotion rules.

However, this does not mean you should take resources away from Kimberly, Murphy, Williams, or another hero who needs them immediately. The refund happens later, while your current squad needs to function now.

Best Gear for Mason

Mason is an Attack hero, so offensive gear receives the highest priority when he is surviving comfortably in the back row.

Early-Game Gear

M3 Turret	Best early slot to prioritize for Mason’s Attack.
M3 Radar	Useful temporary defensive equipment.
M3 Armor	Adds early survivability until better equipment is available.
M3 Data Chip	Fill the slot but save major resources for stronger gear.

M3 equipment is temporary. Avoid sinking large amounts of Upgrade Ore into blue gear unless a small upgrade immediately solves a progression wall. Resources generally provide more long-term value once you have Epic or better pieces.

Mid-Game Gear

M4-A Destroyer Cannon	First Epic priority for improving Mason’s damage.
M4-A Jackal Data Chip	Strong second Epic piece for an active Mason.
M4-A Seahawk Radar	Use when Energy Damage is cutting Mason’s uptime short.
M4-A Porcupine Armor	Add when Mason needs more Physical Damage durability.

Mason Gear Upgrade Order

1. M4-A Destroyer Cannon
2. M4-A Jackal Data Chip
3. M4-A Seahawk Radar
4. M4-A Porcupine Armor

Do not follow that order blindly if Mason dies before completing his skill rotation. A defensive upgrade that keeps him fighting can produce more total damage than another small offensive increase.

Kimberly and other permanent main-squad carries should generally receive your strongest offensive gear before Mason once they are comparably developed.

Best Mason Teams and Position

Recommended Tank Structure

A five-Tank formation grants the maximum same-type formation bonus of +20% HP, Attack, and Defense once that system is unlocked. That is valuable, but it is not a reason to use badly underdeveloped heroes just to reach five Tanks.

Best Frontline Partners

Best Back-Row Partners

Early F2P Tank Formation

This is a practical progression lineup because Mason does not need to carry the entire formation. Kimberly can receive the strongest offensive investment while Mason provides additional Physical Damage and monster support.

Developed Tank PvE Formation

For specialized monster damage, test alternative positioning as well. Moving a durable Mason forward can sometimes let another Tank attacker occupy the back row and receive Zombie Purge. Battle reports should decide the final formation rather than squad power alone.

Where Mason Is Best

Mason for PvE and Bosses

This is Mason’s strongest long-term niche. Do not judge his contribution only from his personal damage number because Zombie Purge can increase the performance of other Tank heroes at the same time.

When optimizing boss damage, compare formations rather than assuming Mason automatically wins. His buff becomes more valuable as the Tank attackers receiving it become stronger.

Mason for PvP

Mason can perform adequately in early PvP because his stars and levels are often higher than premium alternatives. That advantage becomes less important once the roster catches up.

Against other commanders, Zombie Purge loses its monster-specific value. Stetmann or another developed UR hero will therefore usually be the better long-term PvP choice at comparable investment.

Mason Season 1 UR Promotion

Mason receives his first SSR-to-UR promotion opportunity through Season 1: The Crimson Plague. On the documented Season 1 schedule, Hero Promotion opens on Day 1 of Week 2 and the promotion window lasts 42 days.

Newer server schedules and later seasons can offer additional Mason promotion windows, so players who missed the original Season 1 event should check the live Hero Promotion interface instead of assuming Mason can never be upgraded.

Mason UR Promotion Requirements

How Many Shards Does UR Mason Need?

After the promotion, Mason continues using Mason-specific shards and compatible Universal SSR Shards, but the star-up cost is doubled. The documented cost from three-star UR to five-star UR is 1,600 shards.

This is separate from the shards already spent to make the original SSR Mason five stars. Those original star-up shards are not returned.

What Happens to Mason’s Wall of Honor?

Mason can enter the Tank Wall of Honor once the normal requirements are met. His SSR Wall of Honor bonus is Tank Attack, and the bonus improves after he becomes UR.

When Mason is promoted, shards previously invested in his Wall of Honor are refunded and converted into Mason-specific shards. This creates an important preparation opportunity because those shards can help rebuild his UR stars.

When Should You Promote Mason?

Promote when all three conditions are true:

• You have five-star SSR Mason and the Legendary Hero Badge.
• You understand that he will drop to three stars.
• You have enough available and refunded shards to rebuild him without leaving an important squad significantly weaker for an extended period.

If Mason is only a secondary PvE hero, the temporary power drop matters less. If he is still carrying your first Tank squad, preparation matters much more.

Can You Promote Mason After Season 1?

Yes, later promotion windows have included Mason again. Last War Tutorial documents Mason being available alongside newer promotion heroes in later seasons. Availability remains event-based, so use the live Promote button and current event timer as the final authority.

Is Mason Worth Upgrading?

Mason is one of the more practical SSR projects for F2P and low-spending Tank players because he is useful immediately and has a real UR promotion path.

That does not make him a permanent first-priority hero. Kimberly remains the more important long-term Tank damage investment for most accounts, while Stetmann has a stronger general PvP role once developed.

F2P Mason Investment

F2P players should use Mason-specific shards first and be disciplined with Universal SSR Shards. Getting Mason ready for UR promotion is useful, but not if it leaves Kimberly, your frontline, or another critical progression hero badly underdeveloped.

For players considering a different progression route, a developed Last War account for sale is an optional way to start with more established heroes and seasonal progress, but Mason’s investment priority still depends on the actual Tank roster and resources on that account.

When to Stop Heavy Mason Investment

• He has left your main squad and is only used occasionally.
• Kimberly, Stetmann, or another core hero still needs higher-priority resources.
• Your main goal has shifted almost entirely to PvP.
• You cannot support the increased shard cost after UR promotion.
• His existing skills and spare gear already handle the PvE role you need.

Common Mason Mistakes

Using One Skill Priority for Every Mode

Zombie Purge can be excellent in monster content and almost irrelevant against a player. Change the upgrade order according to how Mason is actually being used.

Putting Mason in Front Without a Reason

His normal role is back-row attacker. Only move him forward for a deliberate monster-damage formation when he is durable enough to survive there.

Ignoring Zombie Purge in PvE

Mason’s personal damage is only part of his value. Zombie Purge can improve several Tank attackers at once, making the passive particularly important for boss-focused squads.

Overinvesting in M3 Gear

Blue equipment is temporary. Use it, but avoid spending a large share of your Upgrade Ore immediately before replacing it with stronger pieces.

Giving Mason Gear Before Your Main Carry

Once Kimberly or another long-term carry is developed, that hero should normally receive the best Cannon and Data Chip before Mason.

Promoting Mason Without Understanding the Reset

UR promotion sends him to three stars, resets his skills to Level 1, and removes his current Wall of Honor progress. Prepare first rather than pressing Promote as soon as it appears.

Assuming UR Mason Becomes a Top PvP Hero

UR rarity improves Mason, but the kit remains especially valuable against PvE enemies. His promotion does not automatically make him better than every dedicated UR PvP attacker.

FAQs

What is the best Mason skill priority in Last War?

For balanced SSR use, Quick Reload → Fire Cover → Super Sensing → Zombie Purge is a practical general order. For monster-focused PvE, move Zombie Purge to first priority, followed by Fire Cover and Quick Reload.

What is the best UR Mason skill priority?

For UR Mason’s main PvE role, prioritize the promoted Expertise/stat skill first, the UR zombie-damage skill second, his frequent attack skill third, and the remaining Tactics skill last. Skill names can vary between client versions, so match them by their effects.

Should I upgrade Mason to UR?

UR promotion is worth considering for Tank players who use Mason in PvE and have enough shards to rebuild him after the three-star reset. It is less urgent if Mason has already left all important formations.

How many shards does UR Mason need after promotion?

Under the documented promotion rules, Mason needs 1,600 additional Mason-specific or compatible Universal SSR Shards to go from three-star UR back to five-star UR.

Is Mason better than Stetmann?

Mason is generally more specialized for monsters and boss PvE, while Stetmann is a stronger choice for normal PvP at comparable development. Many Tank players keep both and swap them according to the content.

Should Mason be in the front or back row?

Use Mason in the back row for normal progression and PvP. A specialized PvE formation can move him forward if doing so lets stronger Tank attackers occupy the back row and Mason is durable enough to survive.

Conclusion

Mason is most valuable when you build around what his kit actually does: accessible Tank damage, strong monster support, and a Season 1 path from SSR to UR. Use a content-specific skill priority, protect him in the back row for normal battles, and avoid taking premium gear away from your permanent carries.

If you plan to promote him, prepare for the three-star reset and 1,600-shard rebuild instead of treating the upgrade as free instant power. For more hero builds, seasonal planning, and squad advice, explore our latest Last War Survival guides on Heaven Guardian.
