Really hope it turns out well for you, Cream. I know that situation, it's not a good one, but I'd wager you'd be much better off out of there.
In the meantime, Team Triboar, specifically [MENTION=6801242]GreenKarl[/MENTION], recommend we stay really far away from the Magmin and just keep sniping them with ranged attacks. If Uric can withdraw, I'll have Darathra do the same and Koldan can hit them with a Hail of Thorns to try and just keep wearing them down.
I do not relish the idea of having these things continuously exploding in our faces. Does anyone else have some ranged options, especially some CC Spells? Entangle or anything?
