1 Minimum Requirements for D10
D10 is locked behind level 71. The dungeon scales to your level but has a hard floor on enemy stats — you'll struggle without meeting these benchmarks:
| Stat | Minimum | Recommended |
|---|---|---|
| Level | 71 | 75+ |
| HP | 800 | 1,200+ |
| ATK (weapon + STR) | 180 | 220+ |
| DEF | 120 | 160+ |
| Healing Items | 5× | 10× Major Potion |
If you're below the recommended values, complete D8–D9 for gear upgrades first. The D10 boss Phase 2 transition (at 50% HP) hits for approximately 300–400 damage — you need enough HP buffer to survive it without dying immediately.
2 Gear & Preparation Checklist
Before entering D10, verify every item on this list:
- Weapon: Rare+ quality, level 70+ (Eclipse Greatsword ideal, Crypt Executioner Axe is minimum). Ensure it's repaired at the Blacksmith.
- Armor set: Full 6-piece is recommended — the 6-piece bonus provides +8% DEF which matters for Phase 3.
- Runes: Socket all items. Priority runes: Endurance (HP), Fortification (DEF), Precision (crit). For lifesteal builds, Blood Rune on weapon is mandatory.
- Potions: 10× Major HP Potion (craft or buy — 150 gold each at the Alchemist). Do not enter with fewer than 5.
- Skills: Ensure your 3 active skill groups are set correctly (see best builds section). Wrong skills = failed run.
- Repair: All gear must be at 100% durability. Gear degrades in D10 faster than any other dungeon.
COOLDOWN NOTE
D10 has a 12-hour cooldown after entry (win or lose). Don't rush in underprepared — a failed run locks you out for half a day.
3 Floors 1–9: General Strategy
D10 has 9 regular floors before the boss room. The monsters here are level-scaled to your character and fall into three categories:
- Floors 1–3: Cursed Soldiers — high DEF, low damage. Use skills that bypass DEF (magic damage or % HP attacks). Don't waste potions here.
- Floors 4–6: Shadow Wraiths — low DEF but high crit chance. They can burst for 150–200 damage in a single critical hit. Keep HP above 400 at all times from floor 4 onwards.
- Floors 7–9: Void Guardians — elite enemies with all-stat scaling. Expect to use 2–3 potions across these 3 floors if your stats are at minimum thresholds. This is where underprepared characters fail.
The dungeon room preview (added in the March 2026 update) lets you see the next room's enemy type before entering. Use this — if floor 8 shows a Void Guardian with higher-than-normal HP, use a potion preemptively before entering rather than mid-fight.
4 Boss Phase Breakdown: Abyssal Warlord
The Abyssal Warlord has approximately 4,200–5,000 HP (scales to player level) and fights in 3 distinct phases triggered by HP thresholds.
PHASE 1 — 100% to 50% HP
Standard Combat
The Warlord fights normally: standard melee attacks, occasional Block (+30% DEF for 1 round), and a "Shadow Cleave" attack every 5 rounds that deals 1.5× normal damage.
Strategy: Burn through this phase efficiently. Use your highest-damage skills. Conserve potions — only heal if you drop below 50% HP. The goal is reaching Phase 2 with as many resources as possible.
PHASE 2 — 50% HP (Transition)
Void Surge — Instant Spike Damage
When the Warlord hits exactly 50% HP, he triggers "Void Surge" — an immediate 300–400 damage attack that ignores DEF. This is the #1 kill point for unprepared players.
Strategy: Before the boss reaches 50% HP, ensure you have at least 500 HP. If you're tracking HP carefully, use a potion proactively when the boss is at ~55% HP to ensure you survive the transition hit. After Void Surge, the Warlord gains +25% STR and attacks 20% faster.
PHASE 3 — 25% HP (Transition)
Eclipse Rage — Maximum Threat
At 25% HP, the Warlord enters Eclipse Rage: +62.5% STR (total since Phase 1), -30% DEF. He hits extremely hard but becomes easier to damage. A second instant spike ("Eclipse Crush") for ~200 damage triggers at the phase start.
Strategy: This is a DPS race. Burst everything — use all remaining skills, healing items if needed. The Warlord's -30% DEF means your attacks deal 30% more damage. Lifesteal builds shine here because incoming damage is high but so is your output. Do NOT let him linger — the longer Phase 3 runs, the more damage you take total.
CRITICAL WARNING
The Void Surge (Phase 2 transition) is instant and cannot be dodged — it happens before your action in that round. Plan your HP buffer accordingly. Players with <400 HP at the 50% threshold almost always die here.
5 Best Builds for D10
| Build | Phase Performance | Difficulty | Notes |
|---|---|---|---|
| Vampire DEX Lifesteal | Excellent (P1–P3) | Easy | Lifesteal negates high Phase 3 damage — best for beginners |
| Werewolf STR Burst | P1 fast, P3 risky | Medium | Clears quickly but low HP buffer for Phase 2 transition |
| Hybrid Tank (DEF focus) | Very safe | Easy | Slow clear but near-zero death risk at recommended stats |
| Vampire STR Burst | P1 fastest, P3 risky | Hard | High reward (fastest clear for leaderboard) but execution-heavy |
6 D10 Loot Table
D10 has the best loot table in the game. Every successful clear guarantees a Rare+ item, with a 15% chance of Legendary and 35% chance of Epic:
| Item | Rarity | Drop Rate |
|---|---|---|
| Eclipse Greatsword | Legendary | 4% |
| Nightmare Reaper Scythe | Legendary | 3% |
| Abyssal Plate Set (any piece) | Legendary | 8% total |
| Voidblade | Epic | 10% |
| Shadowstep Claws | Epic | 8% |
| Warlord's Sigil (Accessory) | Epic | 17% |
| Rare weapon (random) | Rare | 20% |
| Rare armor (random) | Rare | 30% |
Additionally, every D10 clear awards 250–350 Dungeon Tokens regardless of loot. These are used at the Endgame Vendor for direct purchase of specific Legendary items (Eclipse Greatsword costs 8,000 tokens).
7 Common Mistakes & How to Avoid Them
- Entering underpowered. If you're at minimum stats (not recommended), you'll likely fail Phase 2. Farm D9 for 2–3 more weeks of gear first.
- Not pre-potting before Phase 2. Track the boss HP. When it hits ~55%, use a Major Potion. The Void Surge will hit you from full HP and leave you survivable.
- Wrong skill loadout. D10 requires sustained DPS across many rounds. Skills with long cooldowns (5+ rounds) are less effective than moderate cooldown skills used repeatedly. Set up your groups correctly before entering.
- Ignoring gear durability. Gear breaks faster in D10. Enter at 100% — broken gear loses 20–40% of its stats. Repair costs at the in-dungeon repair (10 gold per item) are worth it on floors 7–9.
- Saving potions "for later." Use potions when needed. If you have 8 potions and die to save them, you wasted the run. Floors 7–9 and Phase 2 are the right times to use them liberally.
