I got hold of a walk-through on the net a long time back. I was new at RPG then so I used it... for some time. There were many mentions of the Minor Spell Sequencer. But I never came across anything of the sort. It was described as a thing which would make the character using it to go through a set of spells without stopping. So you press one button and 3 or 4 spells are cast one after the other. It'd be really cool if it were actually there. But is it...?

Long story short, yes.

Read the following site for more information. Under the General Spell Info section, under Triggers.
