My player's are having the same issue with backgrounds and origin feats. This previously worked correctly.

If I choose the Cultist background and fill out the spells, it does not appear on the main character sheet.

I posted this on the legends of avantris discord server 

Hey quick question on beyond the experiment background when you choose natural armor.... I made a level 1 barbarian with no armor on. He has an ac of 30.... dex +3 con +4.... is this correct or is it an error on beyond?..... this is a response from the legends of avantris discord server (not an official response from the group.) 

this was the best response I got

"I think what has happened is that because you are a barbarian with the Experiment background, it gives you the barbarian Unarmored Defense (10) plus your Dex modifier (+3) and then, because you chose the Experiment background, that has given you another 17 for Natural Armor: 13 + your Con modifier (+4) = 17. Instead of just replacing your barbarian's AC with the Altered AC, it has added it instead."

I am  in full agreement with the reply

has anyone else seen this before or know what's going on? 

Sinner Hex Slinger has a resource box now thank you guys so much!

There's other subclasses with issues similar but this is really nice and shows promise thank you guys!

Is there any word on when or if the Grim Harbinger’s Grim will get its stat block on the character sheet like the beast master.
