Assassin Abilities - Remove Concentration Check

[RedGiant]

Assassin invisibility, darkness, ghostly visage seem to be treated just as spells, meaning they require the associated concentration check to use in combat. I'm aware of some of the lore here, but as a QoL NwN thing, could they be treated like abilities and/or instant actions?

Rationale: In PnP, Assassins are almost like Rangers and Paladins in their spell-casting ability: they are martial-caster hybrids, they possess a similar sized spell list, but have an even faster progression (4/4/4/4 by lvl 10). In NwN, we only get three spells from what should otherwise be a list. So who in their right mind is going to spend the precious skill points and/or feats required to be a good caster, when your spell list is only three?

Thanks!

It's a good point.

Approved.
