once your in, just enter the portal that is near you and..
just take out either one of the 4 prock phantom s that are located at each corner
they are weaker than the actual thing you have dealt with recently
and pick up the blue stone and proceed to the gate asap
2nd floor
mazy but not hard to memorize
pepens in there deal over 1000 with their headbutts, so just eliminate them quickly
and the squirrels are able to deploy beam gun units until you got rid of the buggers
hound's shot gun do freeze, so just take them down quickly
and the big moth has freeze shot gun, so just becareful and the argargs does fire grenade shots with cycotes hd
find the blue stones(you only need 2) and find the blue gate
and you will notice there are 2 gates, for the other gate, just don't bother that for now and proceed to the blue gate
3rd floor
nothing, just get ready and move on
boss
a giant big moth
not hard really other than the fact its a bigger sized big moth ruler which freezes and regenerates hp over time, which you cant take your own sweet time
and it blew up.
you can actually get big mth lg 3
and finally the part to complete a big moth
but its not over yet
now you have beaten that route, you can now access the black gate.
for the black stones, you gotta kill the big moths as shown previously on the 2nd floor
3rd floor
go to the left tunnel first
you will see shine busters (they are your allies) fighting delgons and goliaths
eventually you will have to take down that for the black stones that are needed (you will deal with them 3 times)
don't forget to grab the purple stone on the way
and go onto the other tunnel
for the same enemies except for this
get rid of that asap and again proceed
4th floor
there are 3 portals
one sends you back to where you first came in (deep section)
and the other shown
boss
sweeper(you can call it gultred) zero
same as the original... with many rippers that you have met in the mission
just do the usual way you have be doing with
you can get a tradable version of its mini counterpart parts as a reward (not sure about bd so far)
and the other gate in the previous floor.
to actually access that, you have to talk to the npc that is beside it and exchange 15 ice and show pieces for a pass(expires in 7 days) and with that, you can now access it.
boss
..... really...? classic builds.... and they even used a collab robo body on it..
really hit hard and theres 4 of them
they too regenerate hp over time
however when one is left, it will be doing something which you gotta take it down quickly , but I don't know what its going to do since it was dead before it could do that..
but I recommending weakening them first before finishing them off (you have to be quick of course)
blew up too
you can get asg bses as a reward
and also new weapons
