- Evolution (aka Evolution Synthesis) lets you power up flower knights to new forms. The second level of evolution is called Blooming.
- Equipment Synthesis lets you level up or evolve Equipment.
- Refining lets you change items into other items. It is technically not a form of synthesis because it does not fuse multiple things together, but the usage flow for refinement is very similar.
