Blessing and Enhancement
Blessing enhances equipment levels with crystals, increasing weapon damage or armor and helmet HP, with failure risk at higher upgrade attempts.
Source basis
The blessing page says weapons, helmets, and armor can be enhanced with crystals from Cave of Crystal, and failed enhancement still consumes gold and crystals.

Wiki notes
Failure risk
The source notes that an enhancement attempt can fail. When it fails, the item does not gain the level, but the gold and crystals are still spent.
Higher levels cost more resources, so it is better to enhance intentionally instead of burning materials after every run.
- Check the displayed success percentage.
- Keep reserve gold before pushing high levels.
- Prioritize the piece that solves your current bottleneck.
What to do in game
Enhance weapons first when damage is the limiting factor.
Enhance helmet or armor when survival is blocking clears.
Stop before expensive attempts if you cannot afford several failures.
