Kecleon with 4 Plus Powers, an Expert Belt, and 4 Cherrims on the bench, and 4 special darks attached. Kecleon rolls 3 heads against an active Dialga Palkia Legend for (10 base+60 for heads+40 Cherrims +20 Belt+ 40 Sp Dark + 40 Plus Powers)x4 weakness = 840 damage. Did I do anything wrong?

I managed quite easily to deal 720 damage without weakness with Magnezone Prime, Lost Burning all my energies (14) while Belted. Last shot of the game. It usually deals 300~500.
