Here's my SMN script I spent the better part of an evening working on with help from the IRC. Hope you can make use of it. It optimizes gear for BPs, Elemental Siphon, and auto-cancel script for sneak/shadows/stoneskin.
V2 - Added code to swap to the assigned light staff for “Cur*” and then it will swap back to your last equipped staff (based on what summon you have out/had out last).
V3 - Added code to equip sacrifice torque and other gear for physical only blood pacts.
V4 - Edited a bit of the siphon stuff as it wasn't working when weather was weak to day.
