load up your toolbox with staples before you set of on your journey;this dungeon will tear up your supplies like no other. 99 floors and endless sludge traps and sticky traps will ruin your items one by one. lots of pp zero traps as well. if you're going bring plenty of reviver seeds,cleanse orbs and max elixirs.

i would suggestto bring:
cleanse orb
dive HM
escape orb
huge apples
max elixirs
persim band
petrify orb
reviver seeds
