[quote name='SilverPaw750']Alright, I'm seriously stuck in the Nest of Evil. I'm almost to the bottom; I can easily beat the two Frankensteins, but then in the next room, I CAN'T BEAT THE DAMN ELECTRIC MERMEN THINGS. I've tried lots of things, lots of different co-op attacks, and I can jump around and maybe survive for 5-10 seconds, but as soon as one of them grabs me, I'm as good as dead. How in the HELL do I beat these things?[/QUOTE]
Have Charlotte equip the explosion spell. Use it (with R) when they just get onscreen. You might be able to pop them twice before they get near you, requiring only one hit from a longer, stronger melee weapon of Jonathan's to put 'em down. You obviously want to kill them ASAP, and not let them get close with that suicidal crap that does like 240 damage.
