concentration, 1 minute/mana
As an action, you manipulate time to hasten or slow creatures. Choose haste or slow as the spell’s effect.
Haste. A creature that you can touch or see within 10 meters is hasted 1 for the duration.
Slow. Up to two creatures that you can touch or see within 10 meters and within 5 meters of each other must make a Will saving throw.
On a failure, a creature is slowed 1 for the duration.
A creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.
Augment
You can target one additional creature with haste or two additional creatures with slow for each additional mana expended. The creatures must be within 5 meters of each other when you target them. You can choose to mix and match the effects by hasting one creature and slowing two creatures for example.
You can increase the hasted or slowed level by 1 for each additional mana expended.
