Man, this dungeon's hazard is really easy for me to deal with. *playing Bravely Default* If you step in the purple flowers, your party gets silenced, right? Here's how I don't care:

My party:
Tiz, Thief with Knuckle Lore and Misc. secondary skill set. No spells, doesn't matter. Red Cap for extra damage
Anges, White Mage two-handing the pope stick. I mean Sage's Staff. With a Red Cap, she can DPS with physical attacks.
Edea, Spell Fencer, Red Cap equipped. She's the tank, and can still do damage without spell enhancement.
Ringabel, Black Mage, silence immune.

This dungeon's a chump.
