Nigon is the second underground race.

No, it's not quite a temptation; the only thing that, in my opinion, should connect these two abilities is the formula used to calculate the duration, just to avoid reinventing the wheel. Of course, you could come up with something else, but I think it fits perfectly. Otherwise, it won't be an active ability, as Arandor said – 20% chance of application with melee attacks. Although, in principle, the duration could probably be increased... Illithids have a higher level, and it doesn't always trigger, plus it only works in melee combat, but again, it can happen any number of times in a battle... Anyway, I don't know; if you overcomplicate it, it will become overpowered, but if you leave it as it is, it will probably be less useful than the 1st tier upgrade. We definitely need to think about it. Nigon's favorite magic will definitely be Darkness (since they focus on mind magic, and all mind magic is Darkness), and I suggested making Chaos the second one (10%), and the rest like the other mages, at 8%. And make the race purely magical, with Knowledge as the primary stat to upgrade, then Spellpower, and only after that, Attack and Defense. But Vaishan suggested that Attack should be the primary stat to upgrade, and then Magic, which is a different order. And that Magic should be 50%, followed by Knowledge (around 30%). But maybe it will be overpowered with this setup, what do you think?
