This is one for all those who wish to play evil, black mages with no respect for life (dundundunnnn)
How about a banishment spell? a very rare spell against characters without a need of a duel, that banishes the target to a very deep, dan, dark place in the Death Realm?
It would be incredibly hard to get the required glyphs (yes multiple!) a they would be scattered throughout the far reachers of the world (maybe the final key one in the DR itself, very apropriate). Possibly it would also require a strange, rarte material componant that needed to be made by the caster, enhanted and bound to the caser (think a similar process as the forging of the one ring. no this is not a rip-off, just an example of the time, effort and magical energy required to construct the catylist). To get some of the special parts for the material componant, the player would have to go out on very hard quests, but when he finaly found them, and made the material componant, found the glyphs, he could cast (insert suitably evil, malicious banishment-style name here)!
Theres a slight catch. After al lthat effort, there\'s a 15% chance it backfires. On you. You banish yourself. Thats right.
Why? you might ask? to allow players to roleplay genuinley evil characters. It\'s no point being an agent of darkness if you have to go up and ask a player\'s permision to cleve him in two!
Extension: after a sucessfull banishing, the caster could collect part of the banised player\'s soul. This could be assosiated to another quest requiring the player to do a favour for death, and collect a certin number of souls, or be punished for his evil deeds. (Death want\'s in on the evil action). And the slaying of sutch an evil character in an honorable duel could be used as a roleplay device. a very good one.
