Bahlak, the Sky Seer's tornado is terrible design, especially for melee.

Chaos is my favorite for warrior (as opposed to Sekhema).

For a 10-room inscribed ultimatum, you will alway fight all 3 bosses (chimera, bleed bird, tornado bird).

I haven't died on my warrior yet to the tornado, BUT it is dicey because it drains health pretty fast. I usually run the 10-room ultimatums after I get to 2500 life and have unbuffed armour of at least 15k.

I think the tornado needs a few simple changes:

1. Make it despawn earlier -- the boss should not be comming back into the arena while the tornado is still present. The map version of this boss is worse than the trial version where the map boss will attack you from inside the damn tornado and you can't do anything about it as a melee character.

2. Reduce the size of the tornado -- it occupies about 25% of the arena area. That's an estimate obviously (tornado is a circle inside an arena that is a circle). It leaves some room to move around the edges, but there are also little tornados moving around too.

3. Tone down the damage a little bit. I think the damage is not the worst offender. If points 1 and 2 are addressed, then players have more agency to avoid the damage. At that point, the current damage is probably fine. However if no other changes are made, the damage needs to be reduced by 40-50%.
