Well it was towards the end of the night and our strat was pretty weak. With 45 minutes we almost mastered the first phase, but got destroyed on the transition. I'm going to outline what I think we could have done better in the first phase, and some ideas on the second. I'd love some more input and ideas on this before we head back in there.
Phase 1 venom and tornado positioning:
We had players dropping venom in the place I had literally just said not to drop it. Turn down your music and pay attention to the strat changes. It took 3 attempts to have a clear spot. We have higher expectations then that.
We need to keep a clear area for the knockback - that much was right. When we did have a clean wall the ground was covered in green. This mechanic is described perfectly by icy-veins:
In Heroic mode, if the tornadoes come in contact with Venomous Pools, they will disperse them by throwing poison at the raid for several seconds, dealing high damage that is difficult to avoid. This happens even with tornadoes and Venomous Pools on a different platform than the one the raid is currently standing on.
So here is my new positioning for that phase:
We put ALL the venom on the one side. Tornadoes on the edge of the platform on the other side. The feathers spawn right near the edge.
