You cannot actually do it in vanilla Oblivion, but often when an enemy lands on one, it gives that effect. (though the spike doesn't actually go through them it sticks to their skeleton or something.) Just try pinning bandits to doors with arrows inside wilderness houses, hitting people with magic weapons so they go flying into things, etc. all can be done in vanilla Oblivion. It's one of the fortunate things about its physics system. where can I get vanilla oblivion?? I really want it vanilla oblivion is unmodded oblivion FAIL :wallbash:
