How do you beat Darkrai?

Okay best thing to do as much as you may not want to is leave the dungeon. Level up your Pokemon and get some items. You want to bring a lot of reviver seeds and healing items. Also bring seeds like sleep and stun seeds. If you can put him to sleep on stun him that gives you a better chance of getting attacks in. Hope this helps.

Use gummis to make your Pokemon have the non sleeper IQ then when you battle darkrai use a quick seed then swap places with cresselia. If you have a water type Pokemon teach it blizzard so when you. Swap places just use blizzard and most of darkrai moves are associated with sleep and non sleeper will allow you not to fall asleep, so there for you win

I agree just leave the dungeon,level up your Pokemon and bring lots of reviver seeds,sleep seeds and x eye seeds

Darkai has non sleeper I think but how to defeat just defeat tell me your Pokemon in awnsers and moves and level and ill tell you the best moves for it and ill make a wonder mail for it ok like use moves like earth power discharge earthquig and thosse moves to get them dead
