Arcanalash

Level 3: Controlled Chaos: The wearer gains a +1 bonus to spell attack rolls.

Level 5: Spell Amplification: When casting a spell that deals damage, you can choose to amplify the damage. Add an additional 1d10 of the same type of damage to the spell's effect. Once used, this feature cannot be used again until you finish a short or long rest.

Level 7: Focused Beam: As an action, you can expend a spell slot to unleash a focused arcane beam. The beam is a ranged spell attack with a range of 60 feet that deals force damage equal to 2d6 + the spell slot level used.

Level 10: Overload You can push the Arcanalash to its limits. As a bonus action, you can roll a d20:

Level 13: Arcane Barrier: As a reaction when you take damage, you can use the Arcanalash to create a protective barrier of force. You gain temporary hit points equal to 3d10 + your Intelligence modifier. Once used, this ability cannot be used again until you complete a long rest.

Level 15: Arcane Detonation: Once per long rest, as an action, you can channel all the glove’s energy into a devastating explosion. All creatures in a 30-foot radius must make a Dexterity saving throw (DC = your spell save DC) or take 6d10 force damage, or half as much on a success.

Level 17: Chain Reaction: When you cast a spell that deals damage to a single target, you can use the Arcanalash to chain the effect to up to two additional targets within 30 feet of the original target. Each additional target takes half the damage dealt to the primary target. You can use this feature once per long rest.

Level 20: Infinite Potential: The Arcanalash no longer requires you to roll for Overload. Instead, you can use Overload at will, and the bonus damage increases to 4d10. Additionally, when using Focused Beam, you can target two creatures instead of one.
