Storm of Magic is out now, and it appears that in the magic cards there is an attribute listed that I am not aware of, Bloodgruel. With a new codex coming this fall, (October) it seems likely that something could slip out in Storm of Magic.
So here it is, I will consider this a rumor, until we have more on what is in the codex. Take with salt
not so much a rumour as a confirmation, on looking through the new storm of magic cards i noticed that the lore of the great maw had the spell attribute of Bloodgruel no as im sure everyone knows we currently dont have the any attributes (even though it could simply be done via errata)
Heres hoping for some gnobler casters as well i want fraggle magic
