Considering offers on this item (wiki hasn't seen one for sale since 2012).
This is a fun toy, as the proc does not harm the user (and obviously pbaoe has no limit to targets hit by this).
Supposedly the quest will be re-enabled in Velious - in the mean time this is an amazing toy for PLing an alt 30+, holding some sick AoE agro as a tank, factioning on greens as a non-aoe class etc.).
Unsure on what I would sell it for (if I see an offer I can't refuse, then I'll have to let it go).
