Interesting concept for a spider monster, so they're basically organic battlesuit/mecha which has logical weaknesses from their tech level. Of course in other settings you could bullshit their weaknesses away with magic hermetic seal, but glad author didn't go that route. (they're still midboss anyway, for endgame tier of course go wild, put the controller in extra dimension)
Still I recall that kumo poison acid and other field attacks got no sell, I guess there's no such thing as water resistance (pressure probably works too)
