• No monster respawns
• Pick any key you see, even if it's a blue key You will get pass Chakris anyway So if you don't pick up the key that dropped, it'll disappear and you might not find another one
• The Mutant Energy Ball is useless You seriously don't wanna spend 25m to craft a random Forcium piece
• You need to bring 1m alz with you in order to buy the epaulet required for the procedure of the dungeon
• I finish the dungeon with 10mins left (takes 40mins/50mins). If you're any slower, you'd still have the extra 10mins to do everything.

Walkthrough :

Q1: Click on the Hourglass in the middle of the firewall at the entrance to turn it off.

Q2: Click on the Lion Statue on the left after you've walked up the stairs.

On your way to Q3, there are 2 timed fire walls. I suggest when you die to go near it and buff yourself there and pass right away when the firewalls drop to save time. Also, don't stay too close to avoid getting hit by it.

Q3: Click on the Clock

I suggest clearing out the end of the wall and see if a key drops. The area before the shooting cannons hall will be safe if you clear it.
If a key does drop, proceed to Q4. You don't need to kill all of them.
If not, finish off the rest of the mobs.

Q4: Click on the Tomb

Use High Regeneration and Art of Force Control before going in.
Rush next to a fire cannon to avoid getting hit by the other 3.
As soon as possible, use the Lance Combo (2nd Action bar) on the firewall. With its casting speed and your vamp equips (and of course HP pots), you'll be able to survive.

On the next corridor, lure 4 Obidiants at a time and kill them all.

Q5: Before warping into Nesbite's room, use High Reneration.

In there, blink next to him from the bottom of the stair and cast BM2. He will move his ass to you by himself while you're casting BM2.
Use Art of Force Control and kill him until he dies.
*Don't worry about the Serpent thingy, or you could kill the one that will spawn next to you for fun. I don't ever die by the laser myself so it's no biggy.

Q6: Click on the Statue behind the Legacy Chest.

Lure all the first small cats to the 2 big red cats and kill them.
Lure all the next small cats and kill them.
Lure 5-6 Big Cats by passing through the first 2 and blink to the room where you get the 4 chests.
Kill the sufficient amount of big cats to satisfy the quest or if you haven't gotten a key yet, just kill them all.
Once you've gathered all the crystals, kill the Beetle Tomb near the end and pick up the quest item that will drop.

Q7 : Go back to the middle of the corridor, there will be a stone. Click on it and acquire the Purify Epaulet from the NPC and advance.

Q8 : In the room, click on the purple crystal on the right.

Instantly move next to the Fire Wall and start using combo. This will damage the Fire Wall while killing the quest monsters.
Finish off the Fire Wall while waiting for the next wave of mobs to spawn.
There will be 2 waves of small cats and 2 waves of big cats.
I suggest using High Regeneration instantly when the big cats spawn because they can be troublesome.
At the 4th/last wave, when you see that the fire wall on the other side shuts down, rush pass through it before it turns back on...
You should have around 3 SP Bars at this point.
...Blink next to the cats and start casting BM2.
Kill the cats until you see Chakris' shield wear off.
The time Chakris' shield goes back up, depends on how fast you kill his minions. You'll most likely only need to kill back his minions 1 time if everything goes well and twice if you have to Aura
You should be able to kill him this boss with BM2 but if you can't, extend with Aura.
Use Art of Force Control before using up Aura.

Q9 : After you've killed Chakris, extract the Purify Epaulet and click on the treasure box behind him. You will be teleported to another shooting cannons hall.

Use High Regeneration or you will die unless you're still in BM2+Aura mode.
Rush to the end of the hall and kill the firewall.
After that, go back to Chakris' room and dance to recover some SP Depending on your performance, you'll have 1/2 bars of SP at this point. You will need 3 SP + enough for a combo to finish the rest of the dungeon.
Don't think if you're dancing, you're wasting your time. Because you're actually waiting for the Golem room to fill up (All the mobs don't spawn at the start)

*Depending on the key you've got, you can go and do the side quests before dancing and get your 4 well earned chests.

After you've danced for around 5mins, the Golem room should be ready.
You can go in or dance until you've got 3SP Bars+ (by using High Regeneration to get pass the shooting cannons hall)
Use BM2 when you're in the room and try to go in the center and lure every mob and start killing.

After you've cleared the room and the door to the next part is opened. Go back to Chakris' room for a little break/dance if you don't have 2 SP Bars +.
When you're ready, use High Regeneration once again to get pass the shooting cannons hall and use BM2 before entering the room with Grogas.

Q10 :Click on the tomb, this will activate a timer that will make the fire wall blocking the access to the final boss drop for a second. Don't forget to be in BM2 before doing this.

Spam the Blink in order to get in the last room before the fire wall goes back up (you only have 1 second). Or else you'll have to kill the firewall to get in the room which is a big waste of time and you will most likely fail the Orca.
Kill Orca.
Use Amulet of Pain instead of Vamp.
Hold CoR+2/Vamp on your cursor and switch up every time you think it's ok.

Q11 : If you haven't done your key quest yet, don't click on the thing behind the boss yet.
