Ok, since the community is still discussing burning mechanisms, here’s my suggestion on this topic.
Every asset in Illuvium should be burnable for substance, with the rarity determining the amount of substance received. This should apply to every asset—I literally mean everything: from IZ blueprints to OW illuvials, ingots, essences, shards, and even Beyond illuvitars, accessories, cosmetic emotes, and battleboards.
I’d like us to first discuss if people like this idea, and then what we might envision doing with this substance. If I remember correctly, Aaron or Kieran mentioned previously that this could be used to fuel our faction’s spaceship. I’d love to hear more of the community's thoughts and ideas on this topic.
