Bless (Dimension 20's Fantasy High variant)

You bless up to three creatures of your choice within range. Whenever a target makes an attack roll, a saving throw, or a skill check before the spell ends, the target can roll a d4 and add the number rolled to the roll.  If you (the player) read this sentence and therefore learn how your spells actually work, your characters can no longer cast this spell (although they can still cast the normal Bless spell if they would otherwise be able).
