The orbs are awesome. You can combine them with jewelry that have empty orb spaces. It literally will say [empty orb space]. You can up you HP, attack power, movement speed etc. Its really handy in the dungeons. You could also try making some blanc cards with the scraps and print some that will help with attack power or ones that make your pet helpfull in the dungeons. You probably already did but maybe i mentioned something that helps. I havent had lag in that area in the game and i havent had problems witht the sardines or the blue frog, so I assume the developer indeed fixed some of the problems.
