Drain spells - ok, they were cool...
But:
Feather - in skyrim is a spell which increases your inventory strength..
Burden - now seriously.. Anyone ever used this stupid spell ? What the hell i need to cast burden onto enemy for ? I do not know if they have inventory (ofc they have none), how full is their inventory, etc..
Mark/Recall - Every dungeon is like a round-trip, you do not need to backtrack them.... Useless in skyrim..
Night eye - never used that one either, i don't want to hurt my eyes..
Water walking - Useless... Unless youre a jesus lol..
