I notice that everyone has jumped on the Tower, but we aren't coordinating at all. The tower is the same for everyone withing the guild so we should share our finding of which floor has the boss key so we can get through the tower as fast as possible. I shared the video above as an example, but we can do whatever Dren wants (he's the boss).
So basically I use my hammer to fill the rest of the team, if I'm stuck there I use Azura to blow up the blues instead. As 40 Titan I'm trying to keep barrier up to eat the skull hits while I charge and fire up Draakulis. He gets big and if things go poorly and my hero dies, I quickly summon a giant using hyndia as a shield. Fortunately Draak is attacking everything with true dmg and getting huge in the event I lose all my shields.
