since now, i havent seen any valid use for those spell
disguise :
go into the dungeon in the beginning after i convince the haflelin to leave, disguise myself, talk to the doorman , succeed in making him belief im the halfelin, go in, HE PROTECC HE ATTACK.
try to freed sazza while in disguise, got caught 'cause i was dumb and forgot about the hidden cave, everyone attack me on sight
disguise myself as a gith to steal to ritual statue, druid : KILL EVERYONE.
since im not that far in the story, avoid specific answer please, but does it only have ''specific,some time used''
read mind:
sincerly, i only seen the action to use it once, it was against donnie .. not the most usefull use. but at lest ive been able to use it once. the other time that could have been usefull was overcome with the ilithid choice.
thought about them :
is it because im still too early in the game?
wont it be a good idea , if the spell is prepare , to have a cutscene right before you engage dialogue giving you the choice that you may need it?
