New crafted items for Treasures of the Riftborne
You need to Enter Mistas to get to the bad guys. Honesty gate to get there.
There are 2 sets of walls blocking the entry. There are some NPCs there.
You use the bombs in the barrel of explosives to destroy the first wall, fight some spawn, use bombs to knock down the second wall, fight some spawn.
Move to the catapult staging area, (in the pic Below) Use the Siege Kits to load the catapults and you fire them. The one who fires gets a handful of rubble.
Once you destroy the wall at the city entry, you go into Mistas and fight.
After the city is clear, you destroy the exit wall with the Bombs to access the main bosses in Ankh Dungeon.
Here are the menus for crafting the items needed for the Siege. That black ball is what the catapults shoot, it shouldn't be there now.

Here are the two new craft able items.
The Elixer lasts 1 hour and does 200% damage to the special event mobs.

Focus on what you can do, not what you can't.

Rubble is also in hidden chests I was told.
Death by Rainbow Unicorn!
There was a server migration that happened after the last event. I think the team is confident that the new servers will not be having any problems.
But this is just my guesstimate.
You can use your Rogue to get them instead.
I hope that they will make void fragments available after this event. It will be awesome if crafters can craft couple semi legendary items with ingredients that are hard to come by like in the old days. Maybe they can add void fragments to some of the peerless bosses in the game. It would add some life to now abandoned peerless bosses. It would be like adding new content to the game without adding new content.
Just my $0.02.
