Tressym stalk and pounce on prey, scratching and biting much as normal cats do, but with the added ability of flight, which makes them far more deadly to birds (and insects) of all sorts. They do not, however, seem to attack nestlings or despoil eggs. In battle, they are cunning - scratching at the eyes of opponents, for example, and learning danger quickly, so that a tressym that sees a wand fired by a wizard knows about the danger of sticks of wood held by humans for the rest of its life.

A tressym recieves a +8 racial bonus on Balance checks and a +4 racial bonus on Hide and Move Silently checks. It uses it Dexterity modifier for Climb checks.

*In areas of tall grass or trees in leaf, the tressym's Hide bonus rises to +8.
