from bulbapedia...Been having issues with Trevenant's Harvest ability not activating when expected so thought I'd better check my understanding of the triggering of the ability.
This is what's happening - Bestow is used, Harvest hasn't yet been skill swapped as I want to retain the berry on Trev and it's been more than 3 turns with no activation. I also have manual sun set before Bestow is used so Harvest should be 100%.
If a Harvest Trevenant uses Bestow to transfer a Leppa berry to the first pokemon in an SOS chain, should Harvest then activate on the Trev or is berry consumption the only trigger?
Since the berry is transferred and not used, this is why you didnt restore it.Harvest can recover Berries consumed by Fling and Natural Gift; however, Harvest cannot recover Berries transferred to another Pokémon, Berries destroyed by Incinerate, Berries knocked off with Knock Off, or Berries eaten with Bug Bite or Pluck. Harvest cannot restore a Berry if it is collected by a Pokémon with Pickup. I
