You’re standing there, staring at a giant winged monstrosity while the timer ticks down in your peripheral vision. It's frustrating. The Throne and Liberty Demon Test—officially known as the 15th floor of Taedal's Tower featuring the boss Stealer of Light—is widely considered the first "real" skill check for solo players in NCSoft’s massive MMORPG. It’s not just a gear check. It’s a dance. If you miss one step, you’re dead, and you're back at the entrance wondering why your health bar disappeared in a single frame.
Taedal’s Tower is a solo secret dungeon. It’s designed to teach you mechanics you’ll later see in 6-man co-op dungeons. Honestly, the 15th floor is where most people hit a brick wall because it demands more than just spamming your highest DPS rotation. You have to watch the boss's hands. You have to time your blocks. Most importantly, you have to understand the light mechanic, or the "Demon Test" will end your run before you even get him to half health.
Why the Stealer of Light is Such a Pain
The boss is a Shadow Demon. He’s fast. He teleports. But the real reason everyone calls this the Throne and Liberty Demon Test is the specific series of trials he puts you through during the encounter. He doesn't just hit hard; he manipulates the environment. You aren't just fighting a mob; you're fighting the room itself.
There are three main phases to worry about. First, there’s the standard melee and ranged poke. He’ll teleport behind you. It’s annoying but manageable. Then comes the "Bowling Ball" phase, as some players call it. He summons energy spheres that track you. If they hit, you're stunned, and in this fight, a stun usually means a restart. Finally, there is the devastating wipe mechanic involving the pillars of light. This is the part that makes or breaks your run.
Most players fail because they get greedy. They see the boss at 30% health and think they can burn him down. Don't. This boss rewards patience and punishes ego. If you ignore a mechanic to land one extra Skill, he will punish you with a high-damage burst that ignores most of your mitigation.
Breaking Down the Mechanics
Let’s get into the nitty-gritty of the fight. The Stealer of Light has a very specific tell for his Fury Attack. When you see the purple circle closing in, you must block. In Throne and Liberty, perfect blocks restore stamina and can trigger powerful counter-effects depending on your weapon choice. If you’re running a Greatsword, a perfect block here is your best friend. If you’re using a Wand or Staff, you’d better have your timing down, or you’ll be chugging health potions like they’re water.
The Light Pillars
This is the "Test" part. The boss will move to the center. The arena will go dark. He starts channeling a massive AoE (Area of Effect) attack that will effectively one-shot most players who are at the appropriate level for this floor. To survive, you have to look for the circles of light on the floor.

Standing in the light is the only way to survive. But here's the kicker: the boss will try to knock you out of it.
- Priority One: Get to the light immediately.
- Priority Two: Keep your finger on the block button.
- Priority Three: Don't stop moving until you are centered in the beam.
Shadow Teleports
Occasionally, the demon will disappear. This isn't a glitch. He’s about to dive-bomb you from above or strike from behind. Watch your feet. A red indicator will appear briefly before he lands. This is a great time to use a mobility skill like the Dagger’s "Shadow Step" or simply dash out of the way. If you get hit, you'll be slowed, making the next mechanic much harder to dodge.
Gear and Consumables: Don't Go in Naked
Look, you can be the most skilled player in the world, but if your gear is still green-tier, you’re going to have a bad time. By the time you reach the Throne and Liberty Demon Test, you should have at least a mix of blue (Rare) gear, preferably enhanced to +6 or higher.
Damage is important, but survivability is king here. If you're struggling, swap out one of your offensive passives for something that boosts Max Health or Damage Reduction. Eating a "Rare Quality" meal before entering the tower can give you that extra 5% health or critical hit chance that makes the difference between a 1% wipe and a victory.
Specifically, look for food that grants "Boss Damage Reduction." It’s a stat people often overlook in favor of raw attack power, but in Taedal’s Tower, staying alive is literally your only job for the first four minutes of the fight.
Common Mistakes Everyone Makes
I’ve watched enough streams to see the same three mistakes over and over. First, players panic-roll. They use up all their stamina dodging basic attacks and have nothing left when the Fury Attack comes. Stop it. Walk away from basic attacks; save the dash for the red circles.

Second, people ignore the adds. Sometimes, smaller shadow creatures spawn. They don't do much damage individually, but they apply stacks of a debuff that increases the damage you take from the boss. If you see them, cleave them down quickly.
Third, and this is the big one, is failing the "Stun Check." The boss has a moment where he charges up a linear strike. If you don't sidestep this, you get stunned. If you get stunned right before he starts his wipe mechanic, you can't reach the light pillar in time. It’s a chain reaction of failure.
Strategy by Weapon Type
How you approach the Throne and Liberty Demon Test depends heavily on what you’re holding in your hands.
Longbow / Staff Users:
You have the advantage of range, but you're squishy. Use your binding skills to keep the boss at a distance as much as possible. When the light pillar phase starts, you have the easiest time because you can keep dpsing the boss while standing in the safe zone. Just don't forget to keep your shield (if using a Wand) up.
Sword and Shield / Greatsword Users:
You are a tank, but don't get cocky. You can soak a few hits, but the wipe mechanic will still kill you. Your goal is to use your high stagger values to interrupt the boss's smaller casts. Use "Stun" or "Shock" abilities to buy yourself breathing room.
Dagger / Crossbow Users:
You’re playing a high-risk, high-reward game. Your mobility is your best defense. Use your "Off-hand weapon" procs to melt his health bar during the windows where he’s stationary. Just be careful with your positioning; it's easy to accidentally dash into a hazard when you're focusing on your rotation.

The Path Forward After Floor 15
Once you beat the Stealer of Light, don't think you're done. The tower goes much higher. However, the 15th floor is the benchmark. If you can clear this, you have the mechanical foundation to handle the late-game dungeons like "Death's Abyss" or "Temple of Slaughter."
The rewards for clearing the Throne and Liberty Demon Test are worth the headache. You’ll get Growth Stones, valuable crafting materials, and a significant chunk of EXP. More importantly, you gain the confidence to handle high-pressure boss mechanics.
If you’re still stuck, take a break. Seriously. Go grind some open-world mobs, upgrade one piece of armor, and come back. Sometimes that extra 200 HP is all it takes to survive a missed block. The boss isn't going anywhere.
Actionable Steps for Success
To wrap this up and get you back into the game, follow these specific steps on your next attempt.
- Check your Stamina: Make sure you aren't entering the fight with a partially empty stamina bar. Wait for it to regen fully.
- Keybind your Health Potions: You should not be clicking these. They need to be on a key you can hit without looking, like 'Q' or a side mouse button.
- Watch the Purple Circle: This is your primary cue. Do not miss a block on the Fury Attack. A perfect block is a massive DPS window because it often staggers the boss.
- Prioritize the Pillar: The moment the screen starts to dim, stop attacking and look for the light. Position yourself early.
- Use a Defense Buff: If you are using a weapon with a defensive active skill (like the Shield's "Counter Barrier"), save it specifically for the phases where you find yourself out of position.
Beating the Stealer of Light is a rite of passage in Throne and Liberty. It’s the moment the game stops holding your hand and demands you play at a higher level. Once you see the "Victory" screen on Floor 15, you’ll know you’ve actually mastered the core combat of the game. Now get back in there and finish the test.
