ToME: the Tales of Maj'Eyal

I really enjoy the game and starting my own mod/addon
So i'm making an addon that include new race of Tree/Ents and a flower race of same caliber

I dont really know how to disable them from learning or acquiring magic/vim related talent tree
but still allow the use of arcane object at the same time

also how do you add damage resistance and water breathing

any help or guide recommendation

if you add
descriptor_choices =
{
class =
{
Defiler = "disallow",
},
it will forbid the player from picking up corrupted classes.
not entirely sure if it could prevent you from getting them elsewhere.

and remember about the tab button.

edit
i managed to block the player from picking any mage class, but the arcane blade still has hiss spells.
so this wont prevent you from picking skills from elsewhere.
