Cosmic Nova
As a last resort, the wielder can unleash the full power of the Zenith Catalyst in a devastating explosion. All creatures within a 100-foot radius must make a DC 40 Dexterity saving throw, taking 600d20 force damage on a failed save, or half as much on a successful one. The Zenith Catalyst is destroyed and if the user some how survives the explosion point blank, they will get something imbued into their body
The Zenith Catalyst
An artifact of immense power and mystery, believed to be a relic from an ancient civilization that reached the pinnacle of magical and technological advancement. The item is a key component in harnessing cosmic energies, allowing the wielder to tap into forces beyond the material plane
Cosmic Channeling: While attuned to the Zenith Catalyst, the wielder gains the ability to channel cosmic energies. They can cast the spell Gate once per day without expending a spell slot. Additionally, they can use the Wish spell once, but after doing so, they lose attunement to the artifact, and the Catalyst becomes inert for 100 years.
Astral Projection: The Zenith Catalyst allows the wielder to project themselves or a willing creature into the Astral Plane. The projection lasts up to 8 hours or until the wielder chooses to end it. While projecting, the wielder can interact with creatures and objects in the Astral Plane but remains tethered to their physical body.
Stellar Manifestation: The wielder can use the Catalyst to create a temporary construct or guardian from stardust and cosmic energy. This celestial being has the stats of a Planetar and obeys the wielder's commands for 1 hour. This ability can be used once per long rest.
Energy Convergence: The Zenith Catalyst can absorb and store magical energy. It can store up to 5 spell levels of energy. The wielder can expend this stored energy to cast a spell they know without using a spell slot, or they can release it in a burst of pure energy, dealing 10d10 force damage to all creatures within a 20-foot radius
Celestial Guidance: The Catalyst provides glimpses of possible futures and celestial alignments. The wielder gains a +2 bonus to all Intelligence, Wisdom, and Charisma saving throws. Once per day, they can reroll a failed saving throw, ability check, or attack roll.
Temporal Stasis: The Zenith Catalyst can manipulate time on a small scale. The wielder can cast the Time Stop spell once per long rest. Additionally, they can use a bonus action to slow time for an instant, allowing them to take an extra action on their turn. This ability can be used once per short or long rest.
Interstellar Communication: The Zenith Catalyst allows the wielder to communicate across vast distances. They can cast Sending at will, and once per long rest, they can cast Plane Shift to travel to a specific location they have previously visited.
Quantum Entanglement: The Zenith Catalyst can bind two objects or creatures together on a quantum level. The wielder can choose two willing creatures, and for the next hour, any damage or healing one creature takes is shared with the other. This ability can be used once per long rest.
