>>33032972Yes you can get some powerful slimes rather easily in this game. This game has a "X/XY monsters" function in which you can fuse 4 low-rank monsters(F to E) to upgrade them to a X version of the monster, much more powerful than the original, and doing it another three times to then fuse them together will get you the XY version of the monster.
You can for instance tame 4 slimes at the beginning of the game, level them all up to lvl20, and fuse them together to get a slime X. You repeat the process three more times and you get a S rank slime that is insanely powerful for what it used to be.
