Alchemist 

Requires: 40 Medicine

Alchemy is a different way to cast Spells, requiring you to prepare Spells during rests. You can spend your intent to make potions, which can be imbued with any Spells you know. You gain a second set of charades equal to your medicine modifier soly to use in the creation of potions. You regain these charades durning safe/unsafe rests if you want an unused potion to last past a rest you must respend the charades. While brewing these potions you can use runes on them, these rune effects linger when the potion is used. To use a potion is an action, anyone can use them.

Coating: A coating potion lets you apply the effects of a potion to a weapon to add the Spell’s damage to its attack for one action.

Throwing: Throwing potions can be thrown, either at a target or on the ground; they cause the effect of the spell to spread out if it doesn't already have an AOE of 3 spaces around where it was thrown.

Drinking: Drinking potions can either cause the person that drank it to have the effect of the spell, or to be able to cast that spell once until they rest. 

When you use a spell that causes an effect on a target and not just damage, the target must do an Arcana save to prevent suffering from the effect. They can choose to fail this. The save is based on your nature score.
