Kalath heads into a convenient shop to buy some stuff.
Sells sword for 1 yen
Sells Phoenix Feather Charm for 1 yen
Kalath purchases Mantle of Shadow and Flame, an enchanted cloak that greatly enhances his abilities (+5 Phoenix, +5 Shadowy, +5 Volcano) for 60 yen. Kalath ends up still having 15.5 yen.
With that done, Kalath decides that he might as well check out what the southeast pillar looks like... after all, he's seen the other three, might as well see the fourth!
Kalath heads south and turns east before reaching the House of Tutul.
