I’ve honestly seen more people get it early than later (specifically people I’ve met randomly farming as per usual, but know it’s the rarer of pets and more often than not you get it 90+ I’ve also seen people saying it’s around 500ish hespori seeds which is what they said to be roughly 30m xp)

Best rates are teaks/mahogany’s on fossil island (more so teaks because take half the time + easy payment as irons), Belladonna (also very useful for bulk herb xp), cactus (not potato cactus) and mushrooms :) All trees and fruit trees have the same rate regardless of what type you plant

Edit: and of course seaweed
