Pokémon Mystery Dungeon: Explorers of Time Tips

Easy way to beat ALL the legends
If you have trouble defeating a legend use this:

1: Have A LOT of reviver seeds (the half bag or more)
2: Have 6-8 sleep seeds
3: Be sure to have a long distance attack

Then go to the Boss and when the boss is in a line in front of you do this:

1: Use you long distance attack
2: When it is in front of you throw a sleep seed
3: Then use you strongest attack
4: When it wake up throw another sleep seed

It worked for me.
