There's a botonist ability that will give you an extra gatherimg attempt, I think you get it at lvl 30. It costs 300 GP per use though so you wont be usimg it every tree. I like using it on the tree that already gives me an extra attempt. Just dont use it right away, take a swing first otherwise it will waste the ability.
Are you sure this works? Every time I've tried using that ability on that same tree, it always says it did not add an additional attempt.
This is confusing considering there's an ability that only works after chain 4. I was always curious if you could use that ability on nodes other than the unspoiled ones.
Your resource node has to be partially depleted before it will work. This is the same as the mining version.
+1 attempt spots give you 1 extra harvest.
Harvest > Ageless Words > Harvest > Harvest > Harvest > Harvest > Brunt Force > Harvest
Chain 5 with 100% crit on the end.
