Battletron

You need to leave 5 "mines" up or he'll re-summon the others into a full circle again.

Any spell or ability that passes through, or near enough to, a "mine" will cause a detonation that inflicts ~90k (pre-squish).
You cannot just stand in the middle on the boss and think you're going to avoid the mechanic.

Ideally you'd destroy 2 of the "mines" directly next to each other, leaving 5 remaining, and use that window to circle him and slowly chip away at his health. However, presently, at 9.6M (pre-squish) it will take sometime and most people who manage to survive the "mines" are still running into the enrage timer.

Just a side note... aren't "mines" under ground typically? I feel like orbs would be a better suited word for these "floating balls." :D

Sounds wrong, very wrong....
