Athachs charge into melee combat unless their opponents are out of reach, in which case they throw rocks. They sometimes try to overrun armored opponents to reach unarmored opponents in back ranks. With its first few melee attacks, an athach tends to flail about indiscriminately. After a few rounds, it concentrates on foes that have been hitting it most often and uses its bite on whoever has dealt it the most damage.

Poison (Ex) Injury, Fortitude DC 22, initial damage 1d6 Strength, secondary damage 2d6 Strength. The save DC is Constitution-based.

Characters with ranks in Knowledge (Nature) can learn more about athachs. When a character makes a successful skill check, the following lore is revealed, including the information from lower DCs.

Knowledge (Nature)
18This huge, portly giant-like creature is in fact an athach, identifiable by its third arm and its unbelievable stench. This result reveals all aberration traits.
23As well as being superb melee combatants, athachs can hurl rocks as skillfully as most giants, and have a nasty poisonous bite that can drain the strength of its victims. Athachs speak a crude dialect of giant.
28Though having no sense of personal hygene, athachs do have a love for the finery of gems, crystals and jewellery – a passion only matched by their love of food and violence. Though fearful of most giantkin, athachs hate hill giants with a passion and will usually attack them on sight.
