16. On the next screen go down the first path. Open the chest to get an archer bandana. Go down and head right to pick up the stamina shoes. Now go left and head down until you reach secret room 5/41. Pick up the 3x mellow nectars. Head all the way back up and continue going right. Check the crystal by the water for another spirit of the pond ambush. When dead check behind it to get a blessed oak cane. Continue right. Open the chest to get a healing potion. Head south and next to the two ponds is a mithril dust. Head south first and open the chest to get an iron clutch.
THIS part is wrong.
In fact, the item is NOT(always) a blessed oak cane, but randomly picked from a list.
Iirc, the list includes Water bow, Ivory Shield, Crude Sword, Malachite Crown, Blessed Oak Cane, CRYSTAL CLAWS(holy, excellent vs humans and dragons claws for guanidia that raise mind among other things, not so good attack-wise, good for the trial), Water sword, and maybe one or two others that I forgot.
The Kayzer crab randomly drops Kayzer crab scales(good armor for guanidia)
Similarly, the ICE SWORD you mention, in the secret room behind the waterfall is randomly picked from a list, the list contains all elemental swords(fire sword, ice sword, earth sword, air sword, water sword, thunder sword).
If you check the water pool in front of the water fall where SARAH was standing(after the dragon fight), you'll find a green ooze.
