I thought this over for a really long time, and i couldn’t think of any, one class that is perfect for this dungeon. So to help you make a decision for yourself, I will tell you the Strengths and weaknesses of different weapon types.
This is personally my favorite weapon type, in UDL it makes fighting Septavis much quicker, and many of the minions are dead in one hit. But Sword users have a major disadvantage against traps, and they are crippled when they enter a room full of slimes, they just can’t really do anything at all against slimes.
All staff users do really good damage for the range that they have, their abilities all affect large areas as well which can help against anything in the UDL, and every time I go through an UDL with a wizard he gets the loot when he only did 200 damage total. Their only problem is that they have low defense, but it shouldn't be a problem if you can avoid projectiles.
A ninja is slightly good for an Undead Lair, as you can outrace even Lair Reapers using your shuriken if you backpedal. The actual use of the shuriken could be used on Septavius, those pesky slimes, the Lair Constructs, or maybe the lair specters. His katana slicing action should be good on the lair ghosts, bands of afterlife dwellers, and maybe even the mini-slimes if you have the defense/recklessness to do so. Do watch out for their low defense though.
Wands are great because they can shoot enemies that aren’t even on there screen, which is great for fighting slimes, and great for baiting other minions to their doom. Any priest though can easily be crippled by quiet shots.
Dagger users have just barely enough range to destroy traps, their damage is better then a ninja, and their abilities are good for damaging someone without taking a hit, rogues and assassins are able to do loads of damage to Septavis without getting hit. Tricksters are good at distracting enemies which is useful to0. Their disadvantages are that they have to regain mp a lot as they rely on it to fight, as well as the fact they don't pierce unless you have the Bone Dagger, which doesn't do particularly good damage.
I love bow users if they have a T8 or above bow, as this can allow them to shoot every enemy in a room at once, their abilities are great for damage dealing and slowing enemies down as well. Their disadvantage is that their bow does very little damage to the boss compared to the minions, and that if you have a T7 bow or below your going to hate fighting in UDL.
In godlands, the Ghost Gods you fight have a chance to drop a Undead Lair, just keep killing Ghost Gods until you find one.
First of all, UDLs are a guaranteed source of wisdom pots, secondly the minions in the dungeon have a higher chance then the gods of the realm to drop T8 weapons and armors, as well as T4 abilities. If you are building a character from nothing this is where you might want to go. There is also a very slight possibility that you could find a Doom Bow from the boss.
Depending on what is awaiting inside of each room, you will have to deal with a different but equally deadly monster group inside. Here are the parts of the dungeon that cause many problems for people. Listed from easiest to hardest.
In every room you enter, along with the other monsters that dwell within, there can be 0~2 traps tiles on the floor. You can destroy a trap before it fires at you, but it can be hard to notice a trap while fighting hordes of enemies. Traps explode when someone gets in a proximity of 5 spaces from it. (If you’re a sword user, you can not destroy a trap, you can only set it off) If you have low defense, traps can do a whopping 80+ damage per bullet, so they are not to be ignored. There are also 2 different types of traps, usually 1 of each per room. There is the the explosion trap that shoots like a wizard bomb, and the shotgun trap that shoots like an archers bow, aimed at whoever set it off.
These brutes are slow moving, big, easy to hit targets that due high damage shots that are also easy to dodge. Though they are not to be underestimated, they also shoot out a shoot that does no damage, but will inflict confuse on a player, which makes them a much deadlier foe. Their confusion shot is much harder to dodge, and if you get confused you could run into there other shots, or even worse, into unexplored rooms on complete accident. Try to use corners as cover when fighting them and you should be safe.
Now for Ghosts, they do not chase you, they do not quiet you, slow you, confuse you or anything else. Ghosts are only deadly to those who are unfamiliar with them. Ghosts can do as much damage as a Ghost God, but while they are dealing this massive amount of damage with there shots, they are also shooting bombs at you, much like a Medusa. Those who are have fought these ghost before, know that the very best way to fight a room of Ghosts is to charge in Leeroy Jenkins style and circle the room to avoid getting multi-bombed by every ghost in the room. Try and kill either the White Ghosts first (because they do the most damage), or kill the Black Ghosts first (because they have the least amount of health).
These guys are just the most annoying thing for priests. Lair Vampires will slow you and/or quiet you with their attacks, they also do about 45 damage each. Now this wouldn’t be so bad, but if you get hit by one slow, you are definitely about to get hit with a quiet, then you will be hobbling away from an angry crowd of vampires, and they seem to have very high dexterity. The best way to kill vampires, is to try and lure them out of a room one at a time, otherwise you will easily be overwhelmed.
The most hated enemy in the entire dungeon, slimes. Slimes are basically a 5 foot high speed bump, they have a range of 9, deal huge amounts of damage, and when you kill them, some smaller ones pop back in there place. If your a priest or a sorcerer you can attack slimes that aren’t on your screen by just shooting in there general direction, if you aren’t, i suggest you use every ability you got. When fighting the slimes, make sure if you kill a big one, you try and kill the little ones that come out instantly afterwards before you have to run back and regain some health. If you are a sword user though, I highly suggest you get a finger ready on your nexus key and try to rush to the next room, if you clear the next room out great, if not, hope you got to nexus.
When you first enter the dungeon, be mindful of how many different directions you can already go, if you have more then one direction to go it is very important that you clear one of the rooms out immediately, and hope that it is just skeletons in there. You need to make sure you have a safe room to run to at all times. If you infuriate 2 mobs with one person, your going to have a bad time, M’kay. Now as you are moving through the dungeon, make sure to kill of side rooms you don’t plan on exploring further, this is just to make sure that while you are running away from a vampire mob, you are not stabbed in the back. Say you are going through the dungeon and you plan to move further down, but there is also an unexplored side path, you should clear the side path first, if the side path goes further, you don’t need to explore it further, you just need that first room cleared of enemies, then you can continue to head down. There are NO treasure rooms in UDL so you need not explore past the main boss. Once you have made it to the boss room, make sure there are no enemies behind you, extra enemies during the boss fight can be really bad, so clear out any side rooms around you before entering the boss room. When you enter the boss room, walk around the wall to make sure there aren’t any extra rooms that you might need to clear out. Once you have circled the whole boss room, and cleared out all extra rooms, you are ready for the boss.
Once you are ready to fight the boss, go up and hit him once, then leave the room, he will then start his spin phase attack, this phase will deal 75 damage to anyone, as it is armor piercing, per bullet. The spin phase can be hard to dodge to some, so just start the fight and wait for his explosion phase to start. As soon as Septavis is done with the Spin phase, he will start his explosion phase, which is just a slow moving 360 degree attack which does 150 damage per bullet, this is a really good phase to get some damage in if you are a range class. As soon as Septavius is done exploding he will go into the quiet phase, this is a phase where he is constantly shooting out quiet bullets that are almost impossible to dodge. They deal 40 damage each to those with low defense. During his quiet phase I suggest you circle him and get some hits in, because during this phase he likes to move towards you and shoot a shotgun of confusion bullets at you, if you circle him, you will only get hit by the quiet shots. After the quite phase is over he will move into his spawning phase, during this phase he will spawn minions, while shooting another shotgun at you, you should circle Septavius and shoot at him while ignoring his minions, this is a really good phase to get damage in, once he starts flashing green use any abilities you have on him. If he still isn’t dead he will start to repeat the phases you have already gone through. If he is almost dead then after the spawning phase, he will move through is various phases for a second each, until he goes back to his spawning phase, letting you kill him much quicker.
A quick way to call this out is to say "UDL"
Good luck with Septavius, I hope this helped you find your own Doombow.
