impact potions

Mechanically, an impact potion works much the same way as a conventional potion. It stores a three success magical effect in liquid (or sometimes a powder), but instead of the target of the spell drinking the potion, someone chucks the grenade at the target.   Typically the potion is kept in glass or ceramic container that is ideally fragile enough to break on contact with a hard surface but durable enough not to break accidentally in storage.   Impact potions have several risks. First, accidental breakage as alluded to before. But also, someone could throw a potion and have it not break when they want it too. Or the thrower can simply miss. Most impact potions have a relatively small radius of effect so throws have to generally be pretty close to the target.   Impact potions can be created by divine or arcane casters, but they are relatively unpopular in most divine circles.   Regardless of type, impact potions use the same basic creation mechanism of regular potions but they cost 20% more in base material cost and some of this cost is because aerodynamic easily throwable containers are harder to make.   While almost any magical effect theoretically be turned into an impact potion, the most common impact potions either store dispel magic or an invocation burst.  

Dispel Magic Grenade

    Impact potions made with Purification ●●● divine magic essentially do the exact same thing only they cost a lot more because it uses a base ●●● effect rather than base ●● though a Purification potions leave behind a more pleasant odor and can also kill germs and/or turn very weak undead.    

Invocation Grenades

    One thing inventive adventurers and soldiers often using wide radius invocation grenades, not as a weapon per se but as a trigger mechanism for booby traps based around highly flammable materials. They are ideal for triggering piles of alchemist's fire.
