Beast is the rune word 'BerTirUmMalLum' for axes, scepters, or hammers in Diablo II: Lord of Destruction. Beast is a rune word typical for characters who use their basic attack as their damage output. With bear form, increased health and defense is always a bonus, on top of the Fanaticism aura. It is commonly also used for Necromancers who depend on their minions.
