When would the berry activate?

Question

Linoone @ Salac Berry
Ability: Gluttony
EVs: 252 Atk / 128 HP / 128 Speed
Nature: Jolly

Belly Drum
Strength / Double Edge
Seed Bomb / Double Edge
Shadow Claw

point of the set is to belly drum up on a switch, then sweep up with Strength, Seed Bomb, and Shadow Claw.

My question asking " how low do I have to get my health, before my berry activates with gluttony? " -- ( note: using Strength because I use this linoone in-game for stuff sometimes.

Answer 1

Gluttony makes the berry activate when your HP is Half so right after using Belly drum. Though if you are going to use it competitively I would recommend having your STAB move Extreme-speed(If you can get one or this is PO) but if you can not get it Return is your best bet.
