Something very strange happened. So, I was just going through UT3 as usual, looted the level and was getting ready for the big fight, then I went into the boss chamber, and there was nobody in there. All plants surrounding the Genetrix were dead, also there was a corpse of a kobold, and a zombie. And the Genetrix herself had gone missing. This was not a bone file. I decided to wait outside the chamber a bit, to see if she still spawned plants. She did, so I figured that she is still somewhere on the level and went back into the chamber to leave. And she was there! She wasn't invisible, I was standing on the tiles she was on before she appeared there. I have no clue how any of these creatures died, or what even happened there, but it is interesting.

Tip: If you get multiple conical friendly mommo slimes and you don't want them destroying the level, then just aggro one of them. They will fight forever, because they are all immune to acid.

Hmm, interesting... I am not really up to date with the current meta, gotta try the armour of great health out again...

I think he means stuff like armor of great health, metal gloves & boots, maybe those disappearing valpurium items

Way too easy for IVAN. There is a reason why important enemies are immune to gas.

Throwing weapons, teleporting, buddies, traps, high dex, maybe high will (idk if it works that way, but it makes sense), praying to dulcius or zapping her. Use everything, be creative.
EDIT: Lots of weak buddies, for the call of a siren easily overwhelms a single strong entity, but many weak targets will make quick work of a siren.

Yep, mustard gas has its own separate type of damage as far as I know

Oh, so the earthquake destroys all mines on the lvl? Thanks for the tip, pretty cool strategy!

An enemy that can randomly destroy your character? Sound like IVAN. And if you get a good one, severe it and then put it back with an angel so it will permanently stay like that.

Long frogs?

Edit: Yay, I am a blink dog!
