Durvla

Durvla is a melee creature in Dungeon Siege II and Broken World.

Back to the bestiary

Template name: siege_bug_stats

Launched from catapults, the Durvlas curl up into a ball, protected from a hard landing by their solid shell. They attack with slashes from their razor-sharp claws. Where they come from is not known, but there are rumors that they are being bred by Dark Wizards for the Morden armies.

The chance is for one kill of this creature (level 33 / 58 / 79 in Mercenary / Veteran / Elite) with magic find at 0: the chance that its drop table rolls an item of this kind, times this item’s share of the items that can come out at that level. Items with the same name are added up. Creatures of the same kind that the Bestiary lists under other names share the same drop table at their own level. Computed from the game’s drop tables, not measured. A source rolls the entries of its drop table; an entry asks the game’s item table for one item of the right class inside a level window; every matching item is equally likely (the game picks a random row, there is no rarity weight). Chance is per kill or per opening, with magic find at 0.
