Guide: Coffin Smasher

In short

Coffin Smasher is a rare HP-based support from the Skinwalkers faction. He excels at placing Decrease ATK (50%) and HP Burn on the Clan Boss, while his passive reduces AoE damage for the team. A must-build for early-game Clan Boss.

Strengths

  • A1 “Hammer Tolls” hits three times with a chance to place a 50% Decrease ATK debuff for 2 turns, useful for removing the Fire Knight’s shield.
  • A2 “Pyre” places HP Burn, dealing damage based on the target’s max HP.
  • Passive “Gloom Shroud” reduces AoE damage taken by the whole team by 5%.
  • Damage scales with HP, so building tanky also increases his damage.
  • Rare champion — easy to acquire and book.

Weaknesses

  • Low base speed (92), needs Speed sets or boots.
  • Debuff chances are unreliable without Accuracy and books.
  • Poor performance in Arena, Faction Wars, and high-level Hard content.
  • Only single-target debuffs, no crowd control.

Where to use

Best in Clan Boss (rating 4.0), especially early game and in unkillable teams. Good in Dungeons (3.0): Spider’s Den and Fire Knight’s Castle, and in Doom Tower (3.0) against Frost Spider. Viable in Hydra (2.5) but outclassed. Weak in Arena (1.5), Faction Wars (2.0), and Chimera (2.0).

Stats and gear

Stat priority: HP%, DEF%, SPD, ACC. Aim for 200 Accuracy for Ultra-Nightmare Clan Boss, 170+ Speed, then stack HP% and DEF% for survival. Sets: Lifesteal (4) + Speed or Accuracy (2). Lifesteal provides sustain, while Speed gives a +5 SPD bonus.

Masteries and blessings

Mastery trees: Survival Speed for support or Destructive Accuracy for damage. Key masteries: Unflinching (RES when debuffed), Nimblemiss (chance to dodge), Buff Depletion (extends debuffs). Relics: Golden Elixir (healing) and Skull of Treason (debuff extension).

Tomes

Prioritize A2 “Pyre” to increase HP Burn chance to 70%, then A1 “Hammer Tolls” to raise Decrease ATK chance to 30%. Passive cannot be booked.

Verdict

Coffin Smasher is a great budget option for early Clan Boss. Worth building if you lack legendary debuffers, but he falls off in the late game.

Gravechill Killer is a Rare Magic Champion from the Corrupted faction of the Knights Revenant. In a team, he serves as an HP-based Support Champion who applies Decrease ATK and HP Burn. In addition to these debuffs, he reduces damage from AoE attacks, so HP and DEF sets will suit him from artifacts.

Where to use Gravechill Killer?

By all its parameters, this hero is definitely suitable for the early-game Clan Boss as a saver (thanks to the passive skill), including in an Unkillable comp. It will also work in the Spider's Den dungeon and the Frost Spider from Doom Tower. Thanks to the basic A1 skill on a 3-turn cooldown, it will be useful in the Magma Dragon's Lair to remove its shield. Of course, you can also use it in other locations if you don't have other good heroes with Decrease ATK, but here everything is situational and depends on the availability of other champions.

Gear. How to build Ravager?

Since Tomb Desecrator is a Support hero with debuff application, the rules of Survivability plus Accuracy are followed accordingly, with the possibility of meeting the necessary Speed. Don't forget that his damage is based on HP, so we maximize this stat through the main HP% parameter in armor and gloves, and in substats on top and artifacts. As for sets, the best are: Lifesteal (4 slots) and Agility or Accuracy (2 slots). It's clear that the Agility set is most beneficial, as it adds +5 to Speed.
