Magically enchanted Splash Weapons.

[Vagabond?]

Can you make magical Splash Weapons, like you would enchanted ammo? Such as a +1 Alchemists Acid, or a +1 flaming alchemist acid?

[MerlinCross]

Huh... I don't think you can?

Personally I wouldn't stop you if you wanted to do it in my own game but only limit it to +1 bonuses.

[Fuzzy-Wuzzy]

You'd have to be able to make masterwork acid first, which I don't think you can.

[Vagabond?]

Gotcha- So that's a no. But could you, for example, cast Magic Weapon on an Alchemists Acid?

Alchemical weapons ARE weapons (that every1 is considered proficient with).
So magic weapon spell should work as the only weapon it is stated not to work with is natural one(which use magic fang spell instead).

also you can use stuff like arcane strike feat, since they work with any weapon, so alchemical weapons should work as well.

FYI I don't think alchemical weapons count as ammo, so spells that enchant 1 weapon or 50 ammunition would enchant 1 alchemical weapon.

Check out the Dimensional Acid Pit (and variants).

These are one shot magic items that affect an area.
