Yes it is, ahahah. I love fusing items trying to get cool names.
It sounds difficult to balance everything, about min mana and stuff. Congrats for your commitment! I root for you! :D And thank you for always listening and taking in consideration the players' feedbacks, it's really nice ^^
I had a question: Is it possible to fuse more items into one monster, if you use two different types of Forge Spark? A normal one and a corrupted one? Or 1 fused item is the max for a monster?
