Protection from Evil, 10' Radius: A Protection from Evil spell which extends to include a circle around the Magic-User and also lasts for 12 rather than 6 turns.These two spells are upgrades of the lower-level spells to "area effect" centered on a particular target (Magic-User or creature/object turned invisible. I'm thinking of upgrading these to the aforementioned 30-foot diameter, even though that improves the spells a bit (15-foot radius, compared to 10-foot radius.)
Invisibility, 10' Radius: An Invisibility spell with an extended projection but otherwise no different from the former spell.
Protection from Normal Missiles: The recipient of this charm becomes impervious to normal missiles. This implies only those missiles projected by normal (not above normal) men and/or weapons. Duration: 12 turns. Range: 3".This spell is less powerful than one would assume just based on the name alone. There's an exemption for "above-normal men", presumably heroes and above, but no level cut-off is given. Since it's a 3rd level spell, we could just say that normal missiles fired or thrown by PCs or NPCs of 3rd level or lower are ineffective.
