Vanity weapons looks great, would look even better with a glow(a suggestion for next designs), I must congratulate you on the design of the staff, it's not a stick this time.
Leaderboards rewards are fine(although some prefer vanity sets over aura or vanity weapons, the recent designs of some of them are better than past lb vanity sets), aura looks really nice, so does the badge and banner, the wisp seems kinda simple looking when compared to frostfire or venom veil, but still is something.
Vendor is not as full of token sales as I would like, but it is an improvement compared to previous events.
Boss dropping level 81 myth art is nice, could be even better if it drop myth 86 too.
The guaranteed will have to be replaced very soon, star beast is getting pretty cheap and even cheaper than kraken weapon/armor.
New artifact is also great, 50% luck, however, I can't say the same (unless a rework of luck stats is planned).
The vanity from locked has a theme too repetitive, it looks like a recolor imo.
