It's good to see Lumian moving forward. Not only with his potion digestion, but also with the sealed artifacts and Inevitably boons. Our guy is getting stronger and stronger. Thanks for the chapter!
Lumian might digest the pyromaniac potion in few more days who knows, Poor Franca it took her almost 6 years to become seq 6. I believe a battle with padre or the wraith using his Pyromaniac abilities, he could digest the potion.
