do take up the quests which required you to take out mobs in there
which you get dark green pieces as rewards( for crafting and exchanging for the dungeon warp)
and also the quests resets daily
and completing all quests will net you 18 dark green pieces total
and as always, all you need is kill, and pick up key stones from the enemies to open the gates
floor 1
larger pigs with rapid firing rifle
floor 2
larger wootrees and pigs
and manimos..
this damtree will summon regular damtrees(does not drop anything)
floor 3
large bats
floor 4
giant centipedes
you have to enter the gates shown
and go to a certain spot to trigger a big black damtree to spawn, take it out
in order for it to drop the gate key(4 total)
but I recommend you to take out all centipedes to make it easier
floor 5
nothing, just get ready and proceed
floor 6
entlos
however, you only inflict very little damage onto it unless you gotten the buff from those magic orbs
touch it to gain the aura
blue aura to inflict damage onto it
and red aura to protect yourself from its special move
this is when you have to get the red aura
you cant avoid that attack regardless how far you are unless your having the red aura buff
(and it hurts really bad)
and it simply retreats
(and it also hints there might be another expansion in the future)
