My first experience with Destrega was on a Offical Playstation Underground Demo Disc. I spent countless months playing it to hell and back. I never found the official game in the wild, I did eventually play it via emulation and completed the story. Which is a lot longer than you'd think. It has a unique battle system, with really likeable characters and attitudes. Mixing up the spells and seeing the results was always exciting.
The advance techniques such as a powered guard, and .... i don't even know what its called, but you'd charge your magic then jump, which allowed you to shoot off all magics in a frenzy.
Its such a fun game. I'd love for this to be saved by the GOG Preservation Program.
