Okay, so here's a bit of stats from the battle so far. We should update this after every post that is made, but this is just a practice battle, so it's not a big deal.

Eric took no damage from the Lurker as it was Provoked by Wren, but you don't have to edit this in your post now. By using Cherry Bomb, the Lurker is now Provoked by Aurelia and it will only attack her. "Provoke" is like your standard "Taunt" from World of Warcraft or any other game with "tanking" classes and skills.

The Lurker took no damage from Eric's Flash Freeze, as it is Immune to Water. However, it did receive the Slow status effect.

Cassie took no damage from the partial Hydro Blast, as the Lurker was Provoked by Aurelia. And I have no way of calculating 'area effect damage' or 'partial damage', but I might add it.

The Lurker's "Muddy Slime" was already exhausted with Wren's combat actions, but we didn't update the Combat Report, so there was no way for the rest of you to know. Most of the Lurker's spirits are exhausted or nearly so because of Eric's "Slow" condition.

Fun Fact: Cassie did the most damage with a single blow because of the "Might" boon on herself and the "Exposure" condition on the Lurker. Congrats!
