Touch of The Void

You touch a creature and that creature is gifted as much of the grand powers of the multiverse as this spell allows. For the duration, that creature gains the following effects:

• The creature's walking speed is increased by an amount equal to half of its walking speed, rounded up.
• The creature gains a +3 bonus to its armor class.
• The creature has advantage on all ability checks and saving throws except for Constitution saving throws made to maintain concentration, on which the creature instead suffers a -2 penalty.
• Any time the creature deals damage with a spell or attack, it can add an amount of additional damage equal to half of the base damage dealt, rounded up.
• The creature cannot be damaged until the start of its next turn.

When the spell ends, the creature is given 2 levels of exhaustion.
