Errors and Mistakes

[Viladin]

Maybe I just don't understand the spell, but I feel there is an error somewhere in this spell.

Temporal Abstraction
Chronomancy
Level: Time Mage 9
Casting Time: 5 rounds
Range: Personal
Targets: You
Duration: Instantaneous

This spell concentrates time, releasing it in a single burst in the round the caster finishes casting the spell. Following the completion of this spell, the caster receives his normal action for that round (plus any additional actions the character may be receiving from haste spells etc.) In addition, the caster receives 1d10 bonus partial actions that he may use either before, or after, his normal actions that round.

What is a partial action? I'm assuming there is either a clarification that didn't get made, or something was incorrectly worded. It just seems strange, mostly because I've never heard of partial actions, and haste doesn't grant additional actions.

It just needs clarification. You gain 1d10 additional actions, standard/move/swift. Partial being that you can choose one of these as your additional action.
