Repeatedly went oom, cast invisibility, conjured a lot of refreshments, opened portals and visited Dalaran, but best staff refuses to speak to a Frost mage. Went Arcane and he reacted to the first portal I opened.
I assume the same goes for Priest knife waifu and Warlock skull thing.
I’m switching my mage to frost this expansion but all the time I was arcane I mogged that ugly staff (never got the cool mage tower appearance) just because I enjoyed his chatter so much.
