Sepulcher Sentinel

Sepulcher Sentinel is an Epic Force-affinity Defense champion of the Knights Revenant, widely regarded as one of the strongest Epics for Clan Boss, rivaling many Legendaries in optimized compositions. Her thesis is sustained Attack denial and debuff blocking that keeps a team safe through the Clan Boss's stun phase.

Core Strengths & Abilities

Sustained Decrease ATK: Her A1, Sword of Withering, has a 40% chance (60% booked) to apply a 50% Decrease ATK debuff for 2 turns, and with an ideal 4:3 speed tune against the Clan Boss — taking four turns for every three of the boss's — she can keep this debuff active for nearly the entire fight. Her A2, Sepulcher Shield, grants the team a 60% Increase DEF buff alongside Block Debuffs, timed to protect the team through the Clan Boss's stun phase.

Clutch Damage Negation: Her passive, Untouched By Death, gives a 25% chance (higher when booked) for an ally being attacked to completely ignore the incoming damage, once per turn — a clutch save that shows up across Clan Boss, Spider Den, and Ice Golem alike.

Key Weaknesses

Speed Tuning Precision Required: Getting full value from her Decrease ATK uptime depends on hitting a precise 4:3 speed tune against the Clan Boss, which takes careful planning rather than a drop-in build.

With a strong Clan Boss rating and excellent Dragon, Ice Golem, and Spider Den scores, Sepulcher Sentinel is a premier Epic-tier tank, valuable as a reliable poison-blocking presence in Spider Den and a general protector in Ice Golem.
