The Edge of the Last Moment

At fifth level by invoking the will of the Great Clock you are able to create a 300 x 300 ft relm for the duration of the spell "ground is mostly flat, and reflective, with occasional lines streaming through it, the sky shows a mess of gears, the atmosphere has an stale feel to it, as little nodes occasionally rise up from the ground, and a giant clock looms over the entire domain, seen from everywhere, counting down the milliseconds at a painfully slow speed" 

At sixth level you gain control of the flow of time in this realm may be chosen when cast :

-Accelerated -- all Characters gain +10 ft movement speed as the thunderous ticking speeds up 

-Perfect Timing -- Creatures cannot gain advantage or disadvantage from environmental effects.

-Delayed -- all characters lose -10 ft movements speed as the subtle whur of gears slow

At seventh level You may create:

Giant gears
Rotating platforms
Massive pendulums
Escapements
Clock towers
Brass bridges
Moving walls
Orreries
Staircases that rotate every round

The battlefield itself becomes a gigantic clockwork mechanism. These features cannot create enclosed structures or trap creatures, and should not provide more than half cover.

At Eighth level  the spell loses the concentration effect and the duration becomes 1 hour. You may now bring Your spell modifier +2 creatures hostile or friendly so long as unwilling creatures fail a dc 15 charisma saving throw. Every round you may rotate, raise, or lower one clockwork feature available at level 7 without using an action.

At Nineth Level  within the next 24 hours you may, as a reaction, cause a recorded moment to repeat eg.Repeat a sword strike, Repeat a spoken sentence, or Repeat a spell of 5th level or lower that targeted only yourself after the spell ends .
