Cracking open the PHB and taking a gander at some of the Paladin spells not yet used, I would like to submit the following suggestions for critiquing and hopeful inspiration to the powers that be.
- Spell Level Clr 1, Pal 1
- Bless a flask (up to 1 pint) of water, turning it into holy water (deals 2d4 damage to undead or evil outsiders), at the cost of 25 gp.
- DDO Suggestion
- Trapmaking and the Flame Arrow spell totally set the groundwork for this. Instead of the normal Spell Component, you need a Crude Vial; it gets consumed on the casting. When the spell is cast, you get a stack of 10 Holy Water grenades. They do 2d6 Good damage to Undead or Evil Outsiders, Reflex equal to the spell's DC for half. No minimum level to use, they expire when you leave the instance.
If we want to throw a little "Trap the Soul" into the formula, we could have the Bless Water spell open up a sub-menu, creating Impure, Pure, and Concentrated holy water grenades. Impure requires a Crude Vial and emulates the stats of a Weak grenade, Pure requires a Simple Vial and emulates the stats and ML of an Average grenade, and Concentrated would use an Unadorned Vial and emulate the stats and ML of a Deadly grenade.
