I just soloed him the other night Thf/Dnc. Had Fajiin boots on so was ready to run on each meteor. I'm taru so the meteor if landed can kill me. I had alot of mdt gear on and twilight neck on just incase he did thunderbolt which he did once and did around 900 damage. Did get kill though.
nah.
you dont need to run.
behemoth can be stunned easily.
would be more worried about that dragon before that floor.
That mfer sometimes one shot even with skirmish gear...
edit: good necro
