The scorpion boss in the hotel scenario the Eject Poison cone attack is MUCH larger than the cone suggests, to about twice as long as the chalk outline implies.
As far as I know it’s unlimited in range…
A boss that definitly has some dodge visuals is DW 2
DW2’s problem is if aggro swaps while it’s casting the filth cone it never places the visual effect but it still kills you. Same in Ankh 4.
