So.. How am I supposed to kill shock and horror?

[[Slayer]]

Just got the map and its corrupted with the mod "two unique monsters". The last stage as two lightning tentacle monsters that uses a lightning beam that utterly destroys me in about 10 secs. I have about 140% resistances in all elements. Not clue what to do. Died twice to it so far (RIP EXP).

[Awesome!]

there are pillars in the room. when he does the beam hide behind one.

this might be made slightly more difficult by there being 2 of them but thems the breaks

If you run around the room without letting them flank you ( using a pillar as cover OFC), you can have both of them fire the beam at the same time giving you the same time window to beat them and run to safety, repeat till they are dead.
Having a good screen resolution will let you see them instead of feeling the beaming first.
