Lichard's Throne
Minotaurs shall not pass! Many bandits and heroes alike try to lay they hands on Sir Lichard's family jewels but his evil magic is much too strong!
Liches are typically princes and kings, so they come from very rich families and tend to keep this tendency to accumulate treasures, but since becoming a lich kind of turns them into an "evil guy", they start attracting all kinds of morons heroes wanting to take these treasures away from the "evil" lich.
Most of these rogues are simply turned into undead minions by the powerful lich, but specially annoying ones might suffer a greater punishment. Behold the Level 99 Necromancer's favorite throne, a masterpiece of the putrification curse!
