So Zephyrus' ATK-down + Snipe will net you 35% ATK-down and 20% DEF-down for 1 enemy, and other enemy if there's multiple, will only get debuff from sniper 20% ATK&DEF-down

Ummm, easier way to say is that C-class debuff is a single debuff ATK-down or DEF-down that stack with everything (ABC,Eidolon)
Ah you're right zephyrus only give you single attack down. I misread it somewhere i guess.
