Get rid of spell writing failure.

What archaic rule is this?
Maybe under the beady glare of a die-hard dungeon master this could be enforced. But with quick save/quick load in a computer game I find this feature annoying.
I'm sure there are some who go along with this rule, but I'd bet my granny they're in the minority.
Low intelligence mages get penalised with a spells-per-level cap.

Also - believe this to be bugged. Even with 100% spell learning many spells still fail to write.
