Whereabouts is Malgen?
EDIT: found him... He is in kobold caves near wizzy port in on NW side of Icefall. Go in and take left fork inside caves and work around. He scowls, attempting to clear kobolds and recon him again.
UPDATE: Finished quest. Killed a couple wanderers first in little intersection just before Malgen's nook. VP and regular root worked. Cleared other kobolds around Malgen to get quest. Altho he scowled, he still didn't attack and gave the quest. All you have to do is head over to the wolves and kill a few mobs and then go back and hail Malgen to accept reward
If you don't have a pup up, and cast the familiar, you get a familiar that looks like our wolf pet, and a buff icon that lasts for like 539 min. But if you say Go Away, both the buff and the familiar go away.
However, if you have a pup up first before calling familiar, when you summon the Wolf familiar, you will get only the icon, and pup sticks around. Best of both worlds.
Regarding Dodge chances stacking:
1: Increase Chance to Dodge by 50%
1: Summon Familiar: CasterWolfFamiliar
8: Increase Mana by 6 per tick
9: Increase Chance to Dodge by 20%
Looks like they should stack
