Yeah I've seen Kamen Rider Ryuki so that gives me a better sense for the abilities. Still not particularly clear on the beast summon though. Like, okay, it's weaker than your character with his armor on but what does it do, what are its abilities, its traits, how does it attack and whatnot? Contracted mirror monsters had a style to them, summoning Dragreder gave you a mechanized chinese dragon that spat fireballs, it definitely wasn't the same as summoning Destwilder and getting a humanoid with a tiger motif doing hit and runs with its claws.
