Lucifer Sigil

Lucifer Sigil is a rare trinket that summons a demonic entity at the start of every battle. The passive spawn provides a consistent frontline presence before the first action is taken, giving your cat an immediate ally to contest positioning or absorb early hits. Its infernal spawn is presumably stronger than typical summons given the sigil's namesake.

SpawnOnBattleStart trinkets deploy their summon automatically at the start of every fight, providing a permanent companion without any action cost. The demonic entity associated with the Lucifer Sigil likely carries fire or infernal attributes, possibly applying Burn or other fire-themed debuffs to enemies it attacks. As a rare trinket (compared to Triachnid at very rare), the summon may be somewhat less powerful, but reliable automatic spawning every battle is a strong baseline regardless of the specific summon quality.

Lucifer Sigil works well on any cat that benefits from a consistent frontline presence. Fire-themed builds that rely on burning enemies get bonus synergy if the summon applies Burn. The trinket is a reliable damage contribution across every fight without the player doing anything beyond keeping the trinket equipped. Pair with summon-boosting mutations or items to increase the summoned entity's stats. For solo cats without party support, a passive battle-start companion provides meaningful HP sponging and secondary damage that can swing close fights.
