Alas, Josh, he has a point. After all, the rules for Sustained Spells only count if the spell itself does not specifically give rules as to its use which supersede the basic rules.

Sustained Effect: Creatures affected must remain outside of

Pushing Through: Normally, an effected entity will do all it
can to stay away from the offending priest, but sometimes
blood lust, rage, or pure hatred will allow it to overcome its
fear. To attack, the Undead must succeed in a Mettle: Perseverance

Okay, re-reading this effect and it does look like Devin has a point here:
1) Only those within a 10' Radius of the initial casting are affected by the spell. Those who are affected are pushed to the edge and cannot enter (even to attack).
2) All creatures outside of the 10' radius are completely unaffected, and can enter the 'bubble' as they please.
3) Those creatures that are affected can reenter the 'bubble' by making a Mettle: Perseverence (Re) roll against the caster.
4) If the creatures FAIL their roll, they can continue to try to enter on subsequent turns.
As such, this ability is FAR more weak than I previously thought it was. This isn't necessarily a bad thing (I'd rather a spell end up being LESS powerful than MORE powerful), but it means I'll have to rethink how to use this spell.
And I'm like Josh in that the speed of trying to break through is the speed of the action they were trying to do when they attempted to break through. If they were doing a basic movement, it is 4 ticks. If they have reach and are trying to attack, it is the speed of the attack.
