While holding the tool, it grants a +1 bonus to your Xirast spell attack rolls and saving throw DCs, and you can use it as a spellcasting focus for your class features.
Additionally, as an action, you can learn a cantrip you don’t know from any class’s spell list. For 8 hours, you can cast that cantrip, and it counts as an Xirast cantrip for you. Once you use this ability, you can’t use it again until the next dawn.
Your All-Purpose Tool’s bonus improves as you level: +2 at 11th level and +3 at 16th level.
You can use this feature a number of times equal to your Intelligence modifier (minimum of once). You regain all expended uses when you finish a long rest.
