This is a pretty simple floor, most of which is devoted to the path to the singular (but awesome) Treasure. To find the Ninja Garb, head through the hidden path on the east side of the starting area. Get used to noticing hidden paths in this dungeon, because there are quite a few, especially early on. Follow this path all the way around to the chest, which is guarded by two RedGiants. The Ninja Garb is absolutely fantastic Armor for Edge, and should not be missed.
There is another hidden path west of the starting area, leading to a teleporter that in turn leads to a hidden set of stairs. This path leads to the Sage Staff and eventually to the Murasame.
When you're done collecting Treasure, head south from the starting area to move on. You'll note that the enemies here are similar to those found on the first floor of Cave Bahamut. Unfortunately, you don't have FuSoYa's Spell list available, so you can't one-shot the tougher enemies until Rydia is fairly high level.
