Universal Reset

You appear to be accelerating, and so is the world around you (Organic matter unaffected). Until the spell ends, your speed is doubled, you gain a +2 bonus to AC, have advantage on Dexterity saving throws, and gain an additional action on each of its turns. That action can be used only to take the Attack (one weapon attack only), Dash, Disengage, Hide, or Use an Object action.

The longer this spell is in effect, the faster time will move. For each round, all effects of this spell are doubled. (+2 becomes +4, then +8, etc. 2x speed becomes 4x speed, etc. You get the picture.)

After 5 rounds, 1 day has passed. After 10 rounds, 1 year has passed.

Once this spell has been cast, it cannot be stopped until the caster is dead. If the caster survives for 20 rounds, the universe is remade, with all PCs starting from the beginning of the campaign.

"Glory to god! We have reached Heaven!!!"
