By the way, I've recently discovered the changes that SR makes to Protection from (Normal) Missile, and the spell now seems very overpowered to me. A 3rd level spell giving complete immunity to all missile weapons in the game? Even high powered stuff like Gesen's Bow and Firetooth? Heck, it even blocks arrows fired by the Fallen Solar and Ascension's Illasera. Seriously, that's way too much.
Couldn't you make the spell scale somehow? For example, it might be more balanced if it granted immunity to normal missiles at level 5, +1 missiles at level 10, +2 missiles at level 15 and +3 missiles at level 20. The +4 and +5 missiles would only be blocked by higher level spells like Mantle and such.
