The real thrill lies in the ‘synthesis and levelling up’ aspect: You gradually level up low-tier gear， then with a single tap， you fuse it into a high-tier item， causing the stats to skyrocket – the sense of progression is quite tangible. Especially when you’ve been stuck on a level for ages and suddenly fuse a high-tier weapon， allowing you to breeze through the next level； that moment is truly cathartic. However， there are a few issues. It’s great fun early on， but later on you hit a bit of a ‘stat wall’. If you’re unlucky or get stuck in the fusion process， it’s easy to get trapped in a cycle of grinding for materials.
