Sin Affinities and Resonance

Every skill in Limbus Company carries one of seven Sin affinities: Wrath, Lust, Sloth, Gluttony, Gloom, Pride, and Envy. Queuing several skills of the same affinity in a turn triggers Resonance, boosting the power of those skills. Chaining three or more matching Sins activates Absolute Resonance for an even larger boost that scales with the number chained.

Resonance also generates the Sin resources that fuel E.G.O skills, so building teams around shared affinities is core to both damage and resource economy. See clashing and coins for how this feeds into combat.
