Maybe the fact that this particular axe is a reward from a DAWNGUARD QUEST that you cannot access from the Volkihar side.
Anyway regarding the axe itself the kill count is supposed to reset but it appears to be bugged and it simply keeps going higher and higher.
Is it really supposed to? that hardly makes sense because you would at most get like 10 kills per area. though i would have thought it would have capped out at some point.
yes...you can get it vamp side just kill them what makes you think you woundt be able too....
Its a quest specific thing. thats like saying dawnguard people can get the vampire amulets and rings.
How can you tell how strong it is? Does the damage rating actually go up? i only have 32 kills so far.
The 32 kills = 32 sun damage.
