How the main combat status effects work — ATK Up, DEF-shred, Burn, Grievous Wound, crowd control, and the Effect Hit vs Effect Res check that decides whether your debuffs actually land.
Increases the carrier's damage output. Stacks from multiple sources are summed, but the buff has a ceiling — past a certain point extra ATK Up sources are dead weight. A character already running near the cap doesn't benefit much from a second ATK buffer.
Reduces the target's Defence so your whole team hits harder against them. The bigger the DEF-shred, the more raw damage everyone deals — this is one of the biggest team-wide multipliers in the game and the main reason to bring a debuffer alongside your damage carry.
Burn is the most common DoT effect. Each stack ticks damage per second based on the caster's ATK at the moment the Burn was applied — so buffing the caster before they apply Burn locks in a stronger tick for the whole duration.
Burn ticks are visible on the target's status bar and can be cleared by any "Remove a negative effect" cleanse. Against World Bosses (no cleanse) Burn is a reliable steady-damage layer on top of direct hits.
Reduces the healing the target receives. It's the counter to sustain-heavy comps and is a tool the World Bosses use against your team. If a fight keeps killing your healer's effort, Grievous Wound is usually the reason — pair sustain with a cleanse or shift to a tank-led mitigation comp.
CC effects come in two tiers based on how much they restrict the target:
Most CC durations sit in the 1-5 second range. Suppressed is the only CC that's undispellable — no cleanse removes it. Standard CC can be removed by "strong cleanse" effects.
Whether a debuff lands is a separate question from how much damage it does. The carrier's Effect Hit is checked against the target's Effect Res — out-stat the target and the debuff lands reliably; fall behind and it gets resisted.
World Bosses carry baseline Effect Res. Bring a dedicated Effect-Hit carrier when you rely on damage-amplifying debuffs landing every cast.
Not every debuff is a damage multiplier:
The takeaway: stacking two of the same kind of debuffer is dead weight. Mix the archetypes — a DEF-shred carrier, a Crit-Resistance shred, and a Burn carrier all multiply each other instead of overlapping.
