MQ2Cast - This is a plugin form of Spell_Routines.inc, and far, far superior. It can, among other things, memorize and cast spells, recast them, and, with the use of MQ2CastTimer, monitor the estimated duration on long term spells like DoTs...
and it should be /bct BARDLIE //casting 1750 gem12
EDIT: actually just tried that with the number and didn't get any result, putting the spell name in quotes, ie. "spirit of wolf" does work correctly. And also, if you are running mq2twist, you may run into a conflict where the bard doesn't stop current twist to execute that command
