Fire Crystals / Forging is stupid.
It's like impossible to get heat level 10 for tier 5 weapons, I quit.
1. Super low-chance of working
2. Takes too many heat crystals
3. A lot of people find it annoying you have to grind just to GET ONE OF THE BONUS FEATURES (heat)
Heat should be free, like in classic SK
What I mean:
Hoarding heat crystals to get level 10 4 star weapons is annoying AF.
It's a stupid concept all-to-gether, heat was originally a bonus feature.
NOW YOU HAVE TO PAY FOR IT.
