Emissary of Time [H]

You draw the flow of infinite timelines to move through your body, briefly suffusing yourself with temporal energy and becoming an Emissary of Time for the duration.

At the start of each of your turns you can choose to emit one of the two following auras in a 30ft radius, changing between the auras ends the previous effect on creatures instantly;

• Aura of Expediency : All creatures of your choice within the aura become affected by the Haste, however they are not affected by the wave of lethargy when they are no longer under the effects of the spell.
• Aura of Lethargy : All creatures of your choice that start their turn within the aura or enter the aura for the first time on a turn must make a Wisdom saving throw or become affected by the Slow. On a success a creature is immune to this aura for 24 hours.

If an affected creature leaves your aura, all effects end on them at the end of their next turn.

As an action you can briefly manifest a blade of compressed time, making a melee spell attack against a creature. On a hit the target takes 3d10 force damage, and takes an additional 3d10 force damage at the start of their next turn.

Additionally, when a creature makes an attack roll against you, you can use your reaction to force them to reroll and the new roll must be used.
