Pokémon Mystery Dungeon: Explorers of Time Tips

Putting on a status effect like hail works well, as the Keckleons will all get hurt even before you steal from it. Also, if you use a fixed-damage attack, it works better because normal strong attacks are like 2HP.

The best combo is Mindreader+sheer cold though, but never use a one-room orb if you do that. Surrouding Kecleon start surrounding you = Dead Pokémon!
