While I craft Minor Sigils of Impact, Fraility, Elemental Slaying, and Luck there are two tiers one beginning which takes an ingot of bronze and some higher which take an ingot of iron and steel and also use higher tier activators. Problem is that both tiers make exactly the same item with the exact same stat bonuses, thus the higher tier made items do not offer any upgrade on the lower tier made items. This seems like a bug. Is it and can this be fixed some how?
