ToME: the Tales of Maj'Eyal

Enemies that can get classes (adventurers, rares, random uniques) often get talents that are completely useless to them, such as a skeleton warrior/berserker getting Rapid Shot while wielding a two-handed weapon.

One way of preventing this would be to mark certain talent trees (in the birth file) as "player-only", or something similar. This would make them slightly stronger, as they would not waste talent points on ones that they can never use.

Most (all?) random bosses do not actually use talent points, but, instead just get max talent level for all of their talents. Talents (but not trees) can have the field .no_npc_use set to true to make them effectively unavailable to npcs.
