Innate invis vs undead? Useless in every way... I think the only mobs it worked vs was against green mobs. The only reason I got it was so I could move freely in Ahkeva, but everything there could see me. I made a post about this a long time ago and I think the response was just it would be overpowering to make it cast a higher level spell the then level 8 or whatever it is. Well, just my two cents... things may have changed... but if it can not even be the same power as the Enchanter ancient invis it should be changed.
