Plenty - potion - entiary is an achievement that requires the player to make an extreme ranging potion from scratch and drink it within the Ranging Guild.
Each step needs to be completed within the area. Bring the ingredients for a super ranging potion (ingredients can be brought in from outside the area), make it inside the Ranging Guild, add the grenwall spikes, and finally drink 1 dose. The achievement will be updated in the achievement as steps are completed. Boosts can be used but must remain when drinking the potion.
