lol , i feel that will be a little greedy having 4 legend books in 1 run xD <| sep |> They ' re dirt cheap . Drain health spells temporarily lower the target ' s health by however many points , but return the health once the spell wears off like with a drain attribute spell . Still kills them if you drain all of their health at once though . Fire damage has a base cost of 5 , damage health costs 8 , absorb health also costs 8 . Drain health only costs 4 . Drain health is only a point lower than elemental damage , but elemental resistance is more common than magicka resist , and elemental immunity is also common . Those points also add up . 500 points of fire damage costs 125 , while it only costs 100 for drain health .
