Choice Specs

Boosts Sp.Atk, but allows one move. (Hold)

Choice Specs is the special attacker's version of Choice Band, boosting Special Attack by 50% at the cost of being locked into one move. On the right Pokémon, this turns already powerful special attacks into absolute nukes.

This item will work best on if your Pokemon has high Special Attack and STAB on a move. Love this item since it helps them get through another Pokémon that would otherwise take hits comfortably. Just remember that being predictable can get punished hard, so you should try switching out when you need to reset the move!
