Question

If a Pokémon with Technician we t last and used Payback, would it have a power of 100, or 150?

Answer 1

100, not 150. Technician only boosts moves that have a base power of 60 or less, and Payback's base power doubles if the Pokemon is hit on the same turn of using Payback.

If the Pokemon using Paypack isn't hit, then Technician boost will apply: 50 x 1.5 = 75.
