OSOGOF seems like the obvious way out with Plantera (if she enrages for a few seconds it's not the end of the world) but imo it constitutes as cheesing, and any form of cheese destroys the point of bosses for me.For plantera, just fly around her in a circle during her first phase and you're set. The seeds travel quite slowly so they're easy to dodge if you maintain a kind of rhythm. Second phase might merit the building of an OSOGOF tunnel (ohoh god oh
) that stretches up to the surface from deep below, because flying around her becomes so much harder.
As for circling I already do that but this woman is a magician, she's not even fast she just appears out of thin air above me. Well no, out of humid, very thick air, this is a jungle
