Zerthimon’s Focus

3-level Enchantment

You channel the energies of the mind into 3 focus die, which are d6s. As a reaction, when you or another creature makes an attack roll, ability check, or saving throw, you can expend and roll the focus die, adding it to the result. You must use your focus die before the DM declares whether the roll was a success or not.
At higher levels: When you cast this spell using a spell slot of 4th-level or higher, the amount of focus die you create with each casting of the spell increases by 1 per spell slot level expended above 3rd.
