Molag Bal (Quest)

With the Hero at level 17 and a Lion Pelt in the inventory, they can approach the shrine. The Hero must corrupt a man to kill them in order to be rewarded by Molag Bal.

Walkthrough
Activate the shrine by giving the lion pelt to Molag Bal. He will tell the Hero to corrupt a man named Melus Petilius. In order to do this, they must make him attack them with the Cursed Mace that Molag Bal provides. He lives at the settlement of Brindle Home.

Head over to the settlement and talk to any villager with a disposition of 60 or more and they will tell the story about Petilius. He moved to a cabin to the southwest of town and he visits his wife's grave daily. One can't get him to attack in his home, but at his wife's grave he is easily angered.

Petilius heads to the grave at 10:00 a.m. so follow him there. It is a short distance from the house he lives in now. When he begins praying at the grave, let them drop the Cursed Mace nearby, then beat him with their fists.

He will start talking and say it was a misstake that they hit him. They must now die and then he grabs the mace. Allow him to beat until death, don't hit him after the first hit as he has a low health and can easily die. When he has hit the Hero to a very low health, they'll then reappear at Molag Bal's shrine and he'll award them with the Mace of Molag Bal.

Trivia

 * Since this quest begins at level 17, it may take a long time to die. If the Blackwood Ring of Silence has been optained, the ring has a deadly Fire Damage enchantment that will quickly deplete all health. One can also go to a nearby large stone and jump down to deplete the health before going back and start the fight.
 * Melus Petilius has a very low health and adding a damage health potion on the mace to harm the Hero is also an option to make it easier to be killed.
 * An alternative to beating him with the fists one can cast the spell turn undead and it will still get him to attack but wont cause him damage.
 * After the quest one can return to the grave and talk to him (or just kill him) and he will give the Cursed Mace back.
 * Should one happen to kill Melus before starting the quest, he will not respawn, making it impossible for him to kill the Hero and impossible to complete the quest.

Bugs

 * There's a particular bug that occurs here occasionally. Once killed by Melus, one may be transported back to the shrine and find the Hero invisible and without any more attribute boosts.
 * A quick fix is to load a save from somewhere before Melus at the grave. Next, go to the grave, just like one should. Drop the mace. Hit Melus Petilius with their hands or whatever low level attack gets his attention. Now, wait for him to say his peace, pick up the weapon, then let him attack once. At this point, open the console using the tilde (~) and type player.setstage damolagbal 60, hit enter and then click on Melus and type stopcombat, hit enter again, then tilde (~) to return from console. One should have gotten a journal entry saying that Melus killed them and were transported back to the shrine. Melus should also not be attacking. From here, just get back to the shrine, click on it, and all should be well. Eventually they aren't invisible anymore, and one may have missed that their attribute boosts disappeared, making a reload anything but a "quick fix." One can, however, use the console command player.addspell spellID in conjunction with this list.
 * On occasion Melus will not pick up the mace and attack hand to hand (a little hard to notice with Melus if he is invisible). If this happens, simply yield, pick up the mace and place it in front of him again (making sure it is on the grave), before attacking him again.
 * On the simply pause, select options then select game play and raise the game difficulty to the highest level. Then, once one have unequipped all of the armor, he will "kill" the Hero very quickly.
