Floor mechanic in expansion questline

Went in with no spoilers, All for One quest; the visual is not well seen. This happened before and when you have HC players, you need to make sure you keep your warning visuals properly overlayed. There are multiple one shot mechanics in the game and until it is brought up, they are hard to make out; manage the timing, ect. New characters are hyper mobile and litter the ground with lights, poison, ect. The floors need a layer that cannot be covered as it one shots HC players. Just like all the other one shot mechanics in the game. Shouldn’t be an issue still at this point.
