Go south from the portal. Then go west to see a chest. Make your way to
it for some Genji Gloves. Head back to the portal, and continue north from
there. At the top of 3F, go all the way west, then all the way south, then
all the way east. Go down the small set of steps into a small corridor. Go
west. You might think it'sa dead-end, but you can walk through the wall.
This should save you some steps. Go southwest to find the portal to 4F.
There are four doors north of the portal. Go through the one all the way
on the right. This'll take you to 5F. Go through the first three doorway
thingys. Once you go through the third, continue ALL the waynorth. Once
you can't go anymore, go ALL the way east. You should go through the wall,
into a corridor. Go ALL the way north, then west to find the way out, and
reach the chest with the Wyvern Lance. Beware, it's guarded by a Black
Dragon. Just blast it with a decent leveled TOAD or TELEPORT. Watch out forit's FLARE though. Head south from the chest, through the little doorway
thingy. Head north at the next doorway thingy, all the way to the top of
5F. From there go west. Don't stop going west. You should be able to walk
through two walls before a pillar gets in your way. Go south a couple steps,
then DIRECTLY west, to find asecret passage to a small room with a chest.
Before you grab the chest, and the Wild Rose, heal up the party. We could
have a fight on our hands.

|TOUGH FIGHT: Lucifer ||----------------------------------------------------------------------------|
| HP:10000 MP:540 | |
| ATK:160 HIT%: 9-100% | |
| DEF:190 EVA%: 1-80% M.DEF: 8-70% | |
|WEAKNESSES: none | |
| STRENGTHS: FIRE, ICE, BOLT | |
| ABSORBS: none | |
==============================================================================
| Cast BLINK ASAP.Lucifer's attack has the drain property, so you'll |
|really want to avoid his attacks. He has a few tricky spells also, so cast |
|BARRIER if you have a low M.DEF. From here, there are a couple of ways to |
|end the fight. Since you have the Wild Rose, you can use it as an item to |
|cast BERSERK 16 on the entire party.A VERY useful feature. This will |
|allow your fighters to attack through Lucifer's high DEF. Spells like |
|FLARE, HOLY, and even ULTIMA damage him. Once you have your defenses |
|buffed, this fight should be easy, as the Wild Rose will give you all the |
|offense you'll need. For a quick win, try a decentleveled(lvl. 9 or so) |
|TELEPORT or TOAD, I told you it was godly. With Lucifer outta the way, and |
|the Wild Rose in your possession, head back to 4F. |

Back on 4F, walk around to the next door to the left. This will...
