Von Leon quick question

What are the phrases on the Boss notification that we need to look out for? i.e when Damage Reflect happens etc.

Those really don't tell you any other then who he is going to teleport to as for damage reflect look a his animation it's really obvious.

When he turns purple, he's using DR.
you can see it coming a mile away.
The notifications just tell you when he teles to someone/debuffs you/summons mobs.
