Jack Simth said:Probably a matter of the formula used for calculating bonus spells: For a given spell level, the number of bonus spells is (about) (4 + Key Ability Modifier - Spell Level)/4 (round down). You'd be getting a bonus spell with a 0 modifier.

Well, you can always prepare them as 1st-level spells...duhtroll said:...How to get more of them short of "extra slot" feat?
