Everyone must soak this ability to split the damage and prevent the boss from pulling the raid off the platform.
Players targeted by her Spinneret's Strands must move away from the raid as they now deal damage and tether all players nearby.
Players now deal damage around them when they spawn adds, so they should spread out and other players must avoid them.
Mythic Changes
New ability: Rasha'nan spits lines of explosive webs. Players hit take heavy damage and are trapped in a cocoon.
3 players now launch waves (instead of 2).
Players targeted by Spinneret's Strand explode 4s after becoming tethered, killing nearby players. Don't get dragged back into the raid.
At least 4 players must soak Web Reave or she throws everyone off the platform.
If the boss casts Acidic Eruption, the raid takes 50% extra damage from that ability until the end of the fight. This stacks. Don't let her cast it more than once.
