This wrench can be used to merge spell effects on the go; as an action, you can touch the item and imbue one of your prepared artificer spells in it, spending a spell slot of the appropriate level. Once at least two spells have been have been placed it it, you can use an action or bonus action to activate the wrench, combining the spells effects and casting it as a single spell.

When combining spells, you can choose only one property of each spell to merge with the other. For example, if you were to combine fireball with chromatic orb, you could combine the damage of fireball with the damage type shifting of chromatic orb, meaning you can switch its damage type. You can combine two sets of damage only if they are of the same type. If you combine dispel magic or counterspell with other spells, they take effect first. You can combine activation types of spells, for example changing fireball into a reaction casting with absorb elements. If any of the spells have a different attack than another (one has save, one has hit), then you may pick which is used.

You can place a number of spells into the wrench up to your intelligence modifier. You may only cast spells from the wrench a number of times equal to your proficiency bonus per day.
