firstly, Lightning Bolt isnt a conjuration. its an invocation. secondly, i have. i killed a lich with sunray once

. also, i killed a rather high-level mage by casting breach on him and then releasing my spell sequencer filled with 2 MMs and 1 Chromatic Orb on him. o and if ye're wantin to know, this was Kyllornious Paac, the lvl 30 (i think) Cowled Wizard that comes up after u beat them to death enough time.
