Without Fortress Guardian:
* Being the target of a succor incurs 1 round lag.
* Self-succoring incurs 1 round lag.

With Fortress Guardian:
* Self-Succoring lag is drastically increased (To normal succor lag when cast on someone else?)

Bug: An edge designed to reduce succor lag actually increases it in some cases.

* Self-succoring incurs 1 round lag.

Are you sure? Because it sure looks like 3 rounds on the caster (whether you're casting it on yourself or not) normally to me, and that seems in line with what I remember from my last pass at acolyte.
