Mass Crystal Consumption  

We trigger the event, and soft tank tormax in his corner near the crystal. Have rangers, enchanters, SK's and monks start to move the shards to the opposite side of the crystal as Tormax. Line them up so you can count them, there are a maximum of 12 that can spawn at one time. When you have made sure there are 12 up, go ahead and continue the event as normal. when yelinak spawns, drag him over to the crystals.

He will give an emote after eating each one.
"[Sat Nov 14 17:40:18 2020] Lord Yelinak's concentration is broken by the crystal shard, and his rain of ice spell is interrupted.
[Sat Nov 14 17:40:18 2020] A disruption shard died."

Make sure you count the emotes so that 12 are eaten during Yelinak's first phase.

After killing yelinak the first time, hold tormax and allow 12 more shards of disruption to spawn. They don't take very long, two seem to spawn every 30-45 seconds.
When you have 12 up, go ahead and dps the crystal down to spawn Dain + 4 coldain + Yelinak. Off tank Yelinak, full burn on the dain and his coldain. After they are dead, pull yelinak over the shards to make sure he eats the last 12. Double check emotes, more will spawn once he starts to eat them so you can force a few extras if you are unsure. One you have 24+ emotes, finish the event as normal.
