if your talking about dragonfable, then talk to Artix in doomwood and click quests, click save moonridge (you might have to do another quest to unlock it) and then click fight waves of the undead ect... once you've killed a wave, you will get a undead slayer badge for training paladin, necromancer or death knight (death knight being the best)
You can use them to train paladin armour.(just go and see artix and 'become a paladin'.)
well, simple. go to zorbak with some undead slayer badges and give them to him. told ya! simple as that!

you must do the necropolis storyline and have 10 undead slayer badges to unlock it. same goes for paladin and death knight.
you have to buy a doom weapon and then you go to artix and click purify doom weapon and he will give you a destiny version of whatever doom weapon you have for ten undead slayer badges. to upgrade to higher level click upgrade destiny weapon(you need ten more undead slayer badges, but that's it). artix is in doomwood by Valencia. (need to be done all artix quests except for last (and be at least level 8) to get destiny weagon upgraded or doom weapon purified) i am level 24 so i have the best upgrade of the destiny weapon :)
