The category rules for 100% says that "All Permanent Fully Upgraded Armor" should be acquired. Since all armor is permanent, this would theoretically include all the upgradable armor sets in the game. However, in an actual speedrun, only the fully upgraded Zora set, Cap/Tunic/Trousers of the Wild, and Champion's Tunic are required (I'm guessing this is because they are linked to quests). It is for this reason I propose that the phrase "All Permanent Fully Upgraded Armor" should be removed from the category rules.
My second question is a random yet simple one - are runners required to activate the horse revival fountain in a 100% run? It is not mentioned anywhere in the rules so I'm assuming not, but I don't want to watch an entire speedrun just to make sure.
Thank you, ~Sibby
