Side by side comparison of Sol's Fafnir on block and Fafnir Roman Canceled on block, as well as Regular Gunflame vs Gunflame FRC.
Paraphrased from The Fighting Game Glossary ([ Ссылка ]):
"[Roman Cancel is] A universal and game-defining mechanic in the Guilty Gear series that lets players cancel a wide variety of moves and return to a neutral state. Players can use this for many offensive strategies, including to extend combos, to apply pressure, or to make certain moves safe. Roman cancels usually cost 50% of your Tension, and are often shortened to "RC"."
"...FRCs only cost 25% of your Tension gauge instead of the normal 50%, making them a very economical and powerful use of meter. ...FRCs can't be performed on just any old move. It's only possible on a small subset of moves (often on projectiles), and the timing is notoriously tight, often just a couple frames of leeway during a very specific part of the move's animation. But when you get used to the precision needed, you can generate some pretty effective pressure at a very low meter cost. "
