I'm not sure if divine locations do. Have been doing hunter and div whenever those spots popped up in the resource dungeon and their pillars are as clean as they were when I planted them
It consumes BXP lol
Smouldering lamps count towards XP for harmony pillars, so if anyone wants to buy the Meilyr title ...
Anything that consumes BXP counts as harmony pillar progress.
I can confirm they do, did divine yews for woodcutting pillars and rocktails for fishing pillars and both worked.
