Haste

Ranged spell
Daily
Target: 
You or one nearby ally
Effect: 

On the target's next turn (not this one, if you cast it on yourself), the target gains an additional standard action.

In addition, at the start of each of the target's turns this battle, if the escalation die is even, roll a d20 and add the escalation die; on a 16+, the target gains an additional standard action that turn.

9th Level Spell: 
The roll for additional standard actions is now 11+ instead of 16+.
