From D&D Wiki
|Casting time:||1 bonus action|
|Components:||V, S, M (A morsel of sugary food)|
|Duration:||Concentration, up to 1 minute|
Invented by the Tabaxi Wizard Nyan Kajan, this spell allows the caster to move at almost exactly the speed of light for a short time. Rainbow-colored lightning wreaths the form of the caster as they appear to blur and shake before vanishing from their immense speed, the only sign that they're still around being occasional flashes of bright light in their path.
Until the spell ends, you have a movement speed of 160,000,000 feet, you gain a +5 bonus to AC, automatically succeed on Dexterity saving throws, are invisible, don't provoke opportunity attacks as a result of entering or leaving a creature's space, and you gain two additional actions on each of your turns. The actions can be used only to take the Attack (one weapon attack only), Disengage, Hide, or Use an Object action. Until the spell ends, you cannot dash and all of your movement speeds cannot be raised in any way. Using your sheer momentum from this spell, you can move across liquid surfaces as if they were solid ground (This provides no protection from the harm those surfaces can cause if moving across obviously dangerous terrain, such as lava), and can run up walls and even on ceilings. If at any point you are forced to stop moving (Besides using all of your movement), such as by your movement speed being reduced to 0 feet, the spell ends.
When the spell ends, you can't move or take actions until after your next turn, as a wave of lethargy sweeps over you. You also gain 1 point of Exhaustion from this draining backlash.
DM Note: The movement speed given above is about 97% the speed of light assuming the character's movement is across 6 seconds (The whole turn). Anything travelling that fast could move around the entire Earth 7 and a half times in one second. A player should reasonably never run out of movement speed, but while outright giving the spell unlimited movement speed would have made things simpler, it would also be much faster than the speed of light, as that would make everything they do instantaneous. Given the Time Stop spell exists, that would make this spell redundant. In practice, actually tracking how much movement a player has spent while using this spell is hopefully unrequired.
