I didn't play during Fontaine, do I need to do anything special against the coppelius?
I've fought the new source automaton boss in IT but it felt like it just started out the fight sitting in its high resistance mode where you're meant to keep its gauge as low as possible by hitting it with cryo, is there more to it than that or is it just one of the stall bosses like wenut and ruin serpent that spends the first 20 seconds of the fight stalling for time?
