Will Hatir Ascendant & Skroll Reborn be available with keys later or only in the forge ?
Dont think, a boss unit will ever appear in the chests. If they do i really fear the chance to get it

These will be the same as the other craftable mythics with their own special recipe (Xantenos, Zuul, Enraged Kurandara, Leonis Tower …). They will never be in chests, but they’re in the soulforge permanently, so you have time to save up / decide when and and if you want them
