All non-human monsters have infravision (see Darkness). Unless specified in a monster’s description, this allows monsters to see in the dark up to 60′.

Monsters do not have a rated INT score like characters do. In cases where an INT score is needed (e.g. charm monster), the referee should decide whether a monster has low (up to 8), average (9–12), or high (13 or more) intelligence. This is sometimes clear from the monster’s description, but if unsure the referee may roll 3d6.

20% of intelligent monsters speak Common (see Languages), unless the monster description states otherwise. Many intelligent monster species also have their own tongue.
