Wall of Honor Guide
What Is the Wall of Honor?
When a hero reaches 5 stars, they are added to the Wall of Honor. You access it through the corresponding troop-type building (Tank Center, Aircraft Center, or Missile Center), which must be level 20.
Once unlocked, you can spend hero shards to level up that hero's Wall of Honor entry. Each hero provides a specific bonus that applies to all heroes of the same troop type — not just the hero being upgraded.
Wall of Honor bonuses stack across your entire troop type. If you upgrade 5 Tank heroes' walls, all 5 bonuses apply to every Tank hero in your squad. This is one of the most powerful passive buff systems in the game.
How Upgrades Work
- No level cap — you can upgrade indefinitely
- Every 50 levels, the hero-specific bonus increases by 0.25% to 1.00% depending on the hero
- You can use hero-specific shards or generic purple shards (universal)
- Purple shards work on any hero — these are your most flexible resource
Shard Refund on Promotion
When you promote a hero from SSR to UR (e.g. Mason or Violet), all shards invested in their Wall of Honor are refunded. Do not hesitate to invest in SSR heroes that you plan to promote later — you lose nothing.
Bonus Types Explained
Each hero gives one of four bonus types:
Attack and Defence bonuses are the most effective for combat. Health is solid but secondary. Troop Load is a utility bonus — useful for gatherers but not a priority for your fighting squads.
Tank Heroes — Wall of Honor Bonuses
Tank Upgrade Priority
- Kimberly — +0.50% Attack. Your main DPS and the strongest attack bonus for Tanks. Always first
- Mason — +0.50% Attack (UR) or +0.25% (SSR). Second attack source. Shards refund on promotion so invest early
- Marshall — +0.50% Defence. Protects the whole squad
- Stetmann — +0.50% Defence. Stacks with Marshall for strong damage reduction
- Murphy — +0.50% Health. Keeps your front line alive longer
- Williams — +0.50% Health. Secondary health buffer
- Others — lower priority. Richard and Farhad give +0.25% Defence which is decent but half the rate. Skip Troop Load heroes unless you actively gather
Attack bonuses increase your damage output across every fight — PvP, rallies, PvE, events. Defence and Health keep you alive, but dead enemies deal zero damage. Prioritise offence, then layer in survivability.
Aircraft Heroes — Wall of Honor Bonuses
Aircraft Upgrade Priority
- Morrison — +0.50% Attack. Top priority for Aircraft offence
- Schuyler — +0.50% Attack. Stacks with Morrison for strong combined attack bonus
- DVA — +0.50% Defence. Your burst carry needs to survive to deal damage
- Lucius — +0.50% Defence. Doubles down on squad durability
- Carlie — +0.50% Health. Front-line survivability
- Maxwell — +0.25% Attack. Decent but half the rate of Morrison/Schuyler
- Others — lower priority
Missile Heroes — Wall of Honor Bonuses
Missile Upgrade Priority
- Fiona — +0.50% Attack. Best attack bonus for Missiles
- Swift — +0.50% Attack. Stacks with Fiona for strong offence
- Tesla — +0.50% Defence. Your main DPS needs protection
- Adam — +0.50% Health. Front-line survivability
- McGregor — +0.50% Health. Secondary health buffer
- Others — lower priority
General Upgrade Strategy
The Priority Rule
For every troop type, follow this order:
- Attack heroes first — the +0.50% heroes are always top priority
- Defence heroes second — damage reduction keeps your squad fighting longer
- Health heroes third — more HP is good but less effective than attack or defence per percentage point
- Troop Load heroes last — only if you actively gather resources on the world map
Shard Management
Focus vs. Spread — and the level 200 cliff
The bonus per Honor Level is flat. The cost is not. Verified in-game:
This guide used to say that one hero at level 200 beats four heroes at level 50. It does not — the two are identical, and the arithmetic is worth seeing. One hero to 200 costs 2,010 shards for 200 levels of bonus. Four heroes to 50 costs 2,000 shards for 4 × 50 = 200 levels of the same bonus. Same shards, same total.
What is not a wash is where you stop. At level 200 the price per level doubles, and it keeps climbing to five times the base rate by level 500. So every shard you put into a hero above 200 buys half of what it would buy on a hero still under 200. Focus up to 200 because the stat jumps feel better and land sooner — then move on, because past that point you are paying double for the same bonus.
So: take your top hero to 200, then rotate. The rotation point is not a rule of thumb; it is exactly where the cost band changes.
Each hero's Honor Level also unlocks extra attributes for every hero of that troop type as it passes 50, 100, 150 and 200 — which is a second reason 200 is the natural stopping point. It is the last of those milestones, and the level the price rises at.
How Wall of Honor Interacts with Other Systems
Wall of Honor bonuses stack with everything:
- Troop type bonuses from mono squads (+20%)
- Hero skills and exclusive weapons
- Gear stats
- Presidential buffs
- Research bonuses
This multiplicative stacking is what makes Wall of Honor so powerful at higher levels. A +2% attack bonus from Wall of Honor gets amplified by all your other multipliers.
Common Mistakes
- Spreading shards evenly — focus on attack heroes first, not a little bit of everything
- Ignoring SSR heroes — their wall bonuses still count and shards refund on promotion
- Prioritising Troop Load — it only helps gathering, not combat. Save it for last
- Forgetting to check the Wall — surplus shards from hero summons sit unused if you do not manually invest them
- Not accessing it through the right building — Tank Wall is in the Tank Center, Aircraft in the Aircraft Center, Missile in the Missile Center. All buildings must be level 20
