Time Stone

The Time Stone is one of the six Infinity Stones, the remnant of a singularity that predates the universe.

Passive
Infinity Stone: This artifact is one of six Infinity Stones. When the artifact is picked up, the user must succeed on a DC 20 Willpower save. The effect is different for each Stone. The user can also automatically succeed this roll if they have a Willpower of 28 or higher.

Power Immune: The artifact is immune to all effects and powers not cast by the wielder. This doesn't extend immunity to the wielder. It cannot be broken, transported (seperately from the wielder), or altered by an opponent.
 * Infinity Stone (Time): On a fail, they are under the effects of the Timelessness spell.

Active
Infinity Spells: The Time Stone allows for the user to use one of these spells once per turn at the highest level. The Stone must be in an acceptable container.

In addition, you gain these abilities:

Choose Destiny: You may roll with advantage on an attack, throw, or check, and see the counteraction of each time up to your Charisma modifier. You may choose which path to take.

Teleport Through Time: You may go backwards and forwards into the past or future in a single location. You gain 1d4 +2 turns to do what you wish before being sent back to the time before. The DM may determine the effects of your actions.

Time Loop: Preemptively setting up to 1d4 conditions, you activate the Time Stone. If the conditions are met, time resets to the point in time where you first started the loop, resetting Player Levels, Equipment, and all other things. You can end the loop as a bonus action.
