In many of these earlier rooms of the final trials, your best bet is to be quick on your feet and to pick up as many arrows as possible. You’ll need every arrow you get in the later trials. All of these rooms have the thunder weather pattern, so avoid using metal weapons and shields, but do pick them up as you’ll need them later.
For now, pick up as many bones as you can get away with, as they are a great way to take down other boney bastards.
Floor 1 – Run straight for the metal weapon in front of you so that you can take down a couple of the enemies at the start. Throw this away as soon as lighting will strike it, or when you have a bone or wooden weapon.
