We plan on opening up the mod's server to the public for you all to receive news about it asap. But for now I can disclose that TR Cain will feature a unique weapon.

I am not a dev of the mod but I can say that Tarnished Cain is like a meele character

Tarnished Apollyon should have an item that has a similar effect to Stitches, because he looks like he couldn't move.

tarnished the lost: no tablecloth, no holy card, no extra lives, you start with a special item that allows you to summon a grass tentacle that deals damage to enemies. His birthright, when stabbing him with the tentacle, will leave him with a debuff called "weed bud" that will release thorns in all directions when he dies
