Fastest way to kill zakum?

5 Bowmasters with Max SE, and 25 Heroes with perfect Lunchboxes (ExtremeBeast-like) and godly Shields.

Honestly I think 25 Heroes with 5 Buccs using perfect 2hs with SI would do better damage. SE is pretty poor for melee classes, and with SI making up the speed gap, Lunchbox loses its appeal.

On the other hand, due to 1h GM scrolls, it might be easier to get 25 perfect lunchboxes. But then again, you can 30% 2h weapons. Wouldn't want to do that to lunchboxes.
