you will find the 2 npcs for instant deep entry and dungeon warp outside the dungeon easily
which uses purple pieces
however, as usual, you will have to go through the normal dungeon first.
as usual, pick up the quests from all npcs and they will reset daily
floor 1
take out the enemies for the stones, however, you will notice multiple gates
with different colored lights at each gate
also to note, the blocky in the dungeon does drop its own bd part
which is rather convenient than hunting it in under gernia
along with the fact the enemies drop parts of mt gacha bots like psycho fomula, snailbot, more weapons etc
and not to mention, you only get to go through 1 gate which leads you to the next floor.
floor 2
multiple octopuses you have faced as bosses from the original dungeon
and 1 oddball from the bunch which varies from the colour gate you've went to
and that odd one out drops the stone to the next floor.
(yellow got blocked by the railgun unfortunately)
red
green
not to mention theres 4 gates ,but you only get to go through one with the respective colour you've picked from the previous floor
floor 3
enter the gate and you will see
purple moles and hatigrams with wild beast hd2
and if you go to somehow the middle, a grandum will spawn and it drops the key to the next floor
once its dead
and the moles do drop mole am2
floor 4
you can ignore the enemies and pick which gate you want
which as has the usual red, blue, yellow and green lights
and you can only pick one gate,
once in, theres 2 gates for you to choose
which is a purple lighted gate
boss
either 4 colour gate
its the enemies you have faced in the 2nd floor
together this time.
and the boss you have to take down varies on which colour you've went to
and your primary target is that shown boss(not the blue one I went for, unless you too went through the blue lighted gate)
rather easy really.
and the purple lighted gate?
2 bosses
one which you will face with on titan cavity (normal) which consists 2
and the other on a sudden mission in a certain map in venev
and in red dragon emergency missions
if you have already faced both of them before as mentioned above
your good to go, focus on one boss first, although the small fry are there to annoy the hell out of you. and they respawn after being killed
still trying to do more of the dungeon so far
