"100% chance to unlock after reaching level 100 without taking any damage" is stated to be the requirement for unlocking Necro. And although it is possible to reduce taken damage to 0 by combing nulldmg potions with certain augments and uniforms, taking 0 damage from an attack still ruins the run.

The by far fastest way to reach level 100 is through the cathedral. Experience gain there is leagues ahead of anywhere else in the game at any challenge level. Running through it at challenge level 0 using the gear detailed below it took me around 12 minutes to reach level 100 without taking any damage and unlocking Necro.

Before beginning you need a character with good piercing damage, to have beaten the Galactic Fleet storyline and unlocked the cathedral.

The weapon we will be using is the vitality scaling Sage's Staff aquired by combining a max level Thornwall with an Omega prism in mech city.

The shield we will be using is the 4th Age Shield which can be aquired at the creation machine in the cathedral using Chaos Emblems.

As for rings we will be using the Roehn Ring which can also be aquired from the creation machine only this time using Star emblems.

The final piece of equipment is the Catastrophia armor set which drops from the ultra boss Catastrophia in the Deep Jungle. And while 300 000 hp seems intimidating Catastrophia is actually multi segmented and can easily be subdued by a piercing weapon with good range. Just remember to bring null dmg potions and anti-poison/monster trainer uniform. Each set piece gives a ridiculous 200 vitality at max level.


In the end your gear should look somewhat like this

We will be using 30 ExpBoost+, 30 ProjectileRange+, 10 MoveSpeed+, 10 DashSpeed+, 5 JumpHeight+ and finally 5 CritRate+.

The Halo augment is necessary as it provides the needed mobility to reliably get through the cathedral without getting hit, but everything else in character creation is up to your discretion.

This is my recommended setup

With all the gear decently leveled and a new character in place you are ready.

First of all you should NOT be running challenge level 3. At challenge level 3 all monster gain a flat +1500 hp and +160 xp drop. The 160 xp is negligible but an additional 1500 hp is a major risk.

First order of business is to kill all Cthu's on sight. These are the only real danger while using the Halo.

Just head towards the exit and keep spamming the attack button. With the help of ProjectileRange+ your attacks should stay on screen long enough to instantly kill any enemies appearing.

The only things to keep in mind is the rocks and to go slowly when you move up or down to avoid aggroing too many enemies.

With your ExpBoost+ gear mods each guardian gives 5000 xp while both Cthu's and Experiment's give 1250 xp.


After around 10 minutes of running the cathedral you should reach level 100 hopefully without taking damage.

Good Luck

There is a bug in the current Roguelands version where stats are not gained properly when you level up multiple times at once. This obviously sucks as we now have the perfect speed levelling gear. Luckily this along with a bunch of other bugs can be fixed by downloading the Unofficial Roguelands Patch mod.
