Aetheric Harmonizer

Weapon (Staff), Rare (Requires Attunement)
The Aetheric Harmonizer is an intricately crafted staff imbued with the power of the Aether, a mystical energy that flows through the universe. It resonates with a vibrant energy, emitting a faint hum as it channels the harmonious forces of the cosmos.
Magic Enhancement: The Aetheric Harmonizer grants a +1 bonus to spell attack rolls and increases the spell save DC of spells cast through it by 1.
Aetheric Channeling: While attuned to the Aetheric Harmonizer, you can use an action to channel the Aetheric energies within the staff. This grants you temporary access to a pool of Aetheric charges equal to your proficiency bonus (minimum of 1). These charges can be expended to enhance your spells or activate certain abilities granted by the staff.
Aetheric Amplification: As a bonus action, you can expend a number of Aetheric charges to enhance the power of your next spell. Each charge expended adds a bonus of +1 to the spell's damage or healing, up to a maximum of your proficiency bonus. The expended charges are consumed after the spell's effects are resolved.
Harmonic Resonance: Once per long rest, you can use your action to channel a surge of Aetheric energy into a target within 30 feet of you. The target must make a DC 15 Constitution saving throw or suffer disadvantage on all attack rolls and saving throws until the end of their next turn as their senses become overwhelmed by the harmonizing energy.
Aetheric Infusion: By spending 2 Aetheric charges as an action, you can infuse your next spell with an radiant effect. The infused spell deals an extra 1d6 damage of the chosen type. This ability can be used once per short rest.
The Aetheric Harmonizer is a potent tool for spellcasters, allowing them to tap into the harmonizing energies of the Aether to bolster their spells and bend the fabric of reality. However, its powers come with a delicate balance, and its true potential can only be unlocked by those who understand the intricate connections between magic and the Aether. Wielding the Aetheric Harmonizer brings both great responsibility and the opportunity for extraordinary feats of arcane prowess.
