Edge Of Eternity

Can't miss this and I happened to get this just exploring off further from Wurldzend off the Kaladaan Coast, having to battle a winged drone beastie (didn't get the name and don't think it's in the bestiary unless it simply falls under, 'Archelite Drone').

Actually an easy battle really even at difficulty 10 with Daryon level 28 with a Crystal Blade maxed at 17 and Selene also at level 28 and a Worldspine Staff at level 18.

Just basic attacks from the rear with Daryon and defense breaker if you have this, keeping out of it's attack radius and using Selene's thunder rift magic attack to hit the emp beacons. Doing so stuns the enemy for a short time so you can land repeated attacks. Didn't even get hit once by doing this and easily got all the objective requirements for this one, one of which is to use all three beacons.
