Noticed since last patch casting requirements (Skill)for teched and unteched spells are now the same. Skill requirements seem to be 10 times the lvl requirements for any spell teched or not. I am not sure if this is supposed to be the case now, though it wasn't in the past. It does sort of makes sense though , in that a teched sword or armour does not need extra skill to use so why would a spell.
