There is only one copy of TM66 Payback in Platinum, and you’ll get it from a black belt NPC standing on Route 215.
He can be found on a mountain cliff located about halfway between Solaceon Town and Veilstone City. He will give you the TM for free if you speak to him.
Payback is a Dark-type physical move that inflicts damage on the target Pokémon. If the user moves after the target, the move’s attack power is doubled (from a base power of 50 to a base power of 100).
TM66 Payback Location (Step-by-Step)
The NPC that provides TM66 is found about halfway between Solaceon Town and Veilstone City, on Route 215. You can access this area once you’ve defeated Gym Leader Fantina in Hearthome City and are therefore able to reach Solaceon Town.
From Solaceon Town, head north through the exit and out onto Route 210.
If you’ve already defeated the trainers in this area, you can save time by using your Bicycle in fourth gear and riding up the muddy slope, bypassing wild Pokémon battles in the tall grass.
Eventually if you keep going north, you will arrive at a building called the Cafe Cabin. In front of this cabin is a path heading eastward. Follow this path to the east.
Soon after starting east, the Route will change from 210 to 215.
Stay moving in this direction until you come to a bridge running north and south, and then climb the stairs and cross the bridge to the north.
Descend the stairs down to the left on the opposite side of the bridge, then turn east and pass under the bridge you just crossed.
Follow this path as it curves southward.
Climb up the two sets of stairs you come across, and you will see a black belt NPC standing at a cliff’s edge.
Speak to him and he will hand over TM66 Payback for free.
Payback Details + Uses
Payback is a damage-inflicting, Dark-type physical move.
|Payback Move Details|
|PP||10 (max. 16)|
While Payback has a low base power, its damage is doubled if the user unleashes it after the target Pokémon has already used a move, or if the target Pokémon’s trainer uses an item or switches the Pokémon out.
Tip: Pairing Payback with a Lagging Tail or a Full Incense held item will slow the user down, potentially making the move more consistently effective.
