The when selecting the species ASI for Scourgeborne it doesn't apply to the character stats. They appear as +0 when selected.

Using the "Weapon Aptitude" of the Grim Hollow human, I can't see the Scythe as an option.

 Could be because you already chose background stats? I don't think DDB lets you choose both at once.

The Weapon Mastery for the Scythe is still not showing up.

The maiden of bones spell isn't tagged as belonging to the Circle of Symbiosis spellist. Come to think of it, that is true of all the osteomancy spells in the Circle of Symbiosis spellist.

Weapon Mastery (Steinhart’s) feat does not exist to be added, so there is currently no way to gain weapon mastery for any of the new weapons.

 It exists. It's just bugged.

Is there any word on if the subclasses and things like the scythe being a ranged weapon will be fixed? This is the first book I’ve purchased on D&D Beyond in years, and as somebody who bought the full Steinhardt’s Guide and enjoyed it, I’m really disappointed with how this has been implemented with seemingly no care at all.

 It would hep if these was SOME system to show that moderators have seen & devs had logged these things.

When activating the Wickerbone Behemoth from the Circle of Symbiosis it doesn't change your AC or make affected by the Barkskin spell, at least not that I could see.

Turns out its just Barkskin being bad :/

The Scythe is set up as a Martial Ranged Weapon when it should be a Martial Melee Weapon.

Barkskin On D&Dbeyond never has you have always had to alter your ac manually so I wouldn't expect it to be any different

Damn, didn't know, another hoop to jump through, thanks Beyond :/

The Scythe is set as Ranged weapon and mess all the DND beyond math lol, appreciate a fix on that, Thank you.

Really happy to see that the Scythe has been updated to be listed as a melee weapon rather than a ranged one :)

Would kindly like to ask again about the new Rogue subclass, to have the Sanctified Champion ability added to the weapon of our choice. Fiddling around with the stats for the weapon seems a bit weird when the ability exist for Warlocks. 

Whenever you finish a Short Rest, you can perform a ritual on a melee weapon you are proficient with that deals Piercing or Slashing damage, sanctifying it. It becomes your sanctified blade, and you can only have one such blade at a time. The blade has the Finesse property for you, and attacks made with it against Aberrations, Fiends, and Undead ignore Resistance to damage.

This might already be known, but I picked Circle of Symbiosis and on the Features & Traits page on my character, I get an option on the Wickerbone Behemoth Feat to change into the Behemoth, however nothing happens when I pick the only option there, Wickerbone Behemoth. I'm thinking its supposed to work sort of like rage? Because I already have the Shillelagh as bonus action. 

Edit: I was wrong, it added STR & WIS attacks to the character sheet, but they end up under "Other" on the Actions page. They should perhaps be moved up to the other attacks that takes 1 action to perform. 

Scythe has been removed from the weapon mastery options
