I don't know the answer. If you know, Tell me, please

it's to mark where to moles dug, it has no meaning in the game just ignore it

First there is nothing in it but when you reach Shadra (the dark planet) go back to nova
and there will be a ladder on the x spot on king's road. Enter it and you will be in
Glissini Caves. It's a training place which is kinda hard. You go down a veeerryy long
ladder which is annoying. Then there's a ladder but a thing a bloking it. Click on it and
its a monster.

There are Clockwork Goats x2, and Ant Noble x2 at level 61.
Use Celestial Swap to power everyone up except Lassi. Sorbet's Absolute Zero should do
around 2100 damage on the Ant Nobles. Be Quick or the will summon another Ant. Chai's
Spellstrike Briar Patch should kill the Clockwork Goats.

Once you kill them go down the ladder and you will find another monster. You should train
here in these Caves. But I don't recommend going in these caves yet. Train at Cromagar
Caves until youre at Level 59. Go back to King's Road and find the X.

Every 5 ladders there is a boss battle. On the 5th floor and 15th floor there are items
for Light and Dark symbols. On the 20th floor there is a boss battle called Umbra. It
fights like Shadra's second form, but harder. If you defeat it, it drops... A putty pea?!

Hmmm... at the end there is something that hepls you defeat Macademeus on Puffoon. You
should be at least 90-99 leveled to defeat him.
Make everyone powered up, and have Pico and Mokka defend.
IQ up Chai and have him use Catcus Crush often and vigoursly.
Everyone else should just heal and IQ UP Chai
again. Pretty easy now, isn't it? You get the Warrior's Nose once you won (What does it
do?)

you can defeat him at some point?
