How do you lure monsters onto an altar when you are evil. for good and neutral i find i have to walk onto the altar to get monsters to go on them. altars rarely spawn in the middle of a room and generally either spawn right next to a wall or one square over. its pretty hard to lure a monster onto an altar if its against the wall and you can't stand on it cause you will get sacrificed.

also how do you drop items onto an evil altar without standing on it? Do you drop and kick?
is it safe to stand on the evil altar in Dwarftown or will someone offer you?
