Gunther Gloomtender

The Necropolis
If you try to talk to him while at level 4 or lower, he will reply:


 * Gunther Gloomtender: YA? YOUR MOTHER'S A HELLHOUND! What? Oh, just some friendly banter with the Silver Fools. Haha...oh don't you worry, we'll breach the gates of the Shadow Knight before they do.

If you are at level 5 or higher, however, he will reply:


 * Gunther Gloomtender: The Tomb of the Shadow Knight isn't going to clear itself out, y'know. What's the hold up?
 * You: What should I expect down there?
 * Gunther Gloomtender: The guardian sleeps in the center of the Knight's tomb. There are 4 annexes, each with an altar inside. Purify the altars and the Guardian will awaken.
 * You: Got it. (Bestow quest)
 * You: I need more time to gather my strength. (Walk away)

Talking to him after acquiring the quest, but before completion, will make him say:


 * Gunther Gloomtender: Why are you talking to me? GET DOWN THERE AND KILL THE MUMMY!

On completion of quest, he will congratulate you with the following:


 * Gunther Gloomtender: I'm flabbergasted! Gobsmacked, even! Ach, we were already dividing up your possessions.
 * You: Sorry to disapoint you, dwarf.

After completing the quest and taking the reward, if you talk to him again, he will reply:


 * Gunther Gloomtender: The mummy is dead, eh? Good riddance. Now let's go after that vampire.
