It’s Week 2 of Halloween! Here’s what’s new.

[Cinco]

A bracelet like this giving bonus movement speed would be great too

There are so many ways to get speed (multipliers and stacking speed bonuses) it didn't seem necessary... or even desirable. That said, the team has a bit of time before tomorrow's update and could put together a suite of these Bracelets that offer a small stacking speed bonus. No promises at this point but we will discuss!

The elixir can be used in any map? Or just the event map?

Halloween Farmer's Elixir is only relevant in the Spooky Woods zone (the primary Halloween combat area) and does not have any effect on bosses outside of this area. It doesn't affect Oligarch or Boogie since they have their own thing going on with unique 'bag' loot and their event points. So you'll probably wind up having to make a choice here... which is always fun :-)

Mb, forgot to ask, this does not stack mean 1st jewel of this type per item or 1st jewel in entire set?

If you socket multiple Mentis Morti Death Shards you'll get the damage bonus from all of them but you'll only get the Critical Hit Damage from one (1) of them. Sorry if that was not clear. I'll rewrite that part of the OP to be more precise.

What level is the Death Shard?

Like the Paracelsus Stone, the Mentis Morti Death Shard is Level 1.

Is the new jewel lost when replaced or removed?

Death Shards are lost when you replace them.

Will this hero flame update tomorrow in game? Right now still shows with haste instead of crit damage? Ty

The updated stats for Flame (and Neigher) will be updated in-game tomorrow.

Best wishes!
