Legendary raid · 2M base HP
Ancient Dragon — the 2 million HP legendary
The capstone alliance raid. Weak to Assault, scaled by the same formula every other boss uses. Here's the actual HP at your alliance, the three comps that beat it, and the reasons people lose.
TL;DR
The TitanSaga Ancient Dragon guide in one paragraph — 2M base HP, Assault weakness, Legendary difficulty. At a level-10 alliance with 10 active members you're fighting 5M HP. Bring max-ATK comps; skip Defend-oriented sets. The 4× reward floor over Iron Colossus is real but only matters if you actually clear — a failed Ancient Dragon attempt loses to a successful Iron Colossus on every metric.
Actual HP at your alliance scale
The server applies 2,000,000 × (1 + level × 0.15) × max(members / 10, 0.5) at spawn time. Pre-computed values:
| Alliance level | 5 members | 10 members | 20 members |
|---|---|---|---|
| L1 | 1.1M | 2.3M | 4.6M |
| L5 | 1.8M | 3.5M | 7.0M |
| L10 | 2.5M | 5.0M | 10.0M |
| L15 | 3.3M | 6.5M | 13.0M |
| L20 | 4.0M | 8.0M | 16.0M |
| L30 | 5.5M | 11.0M | 22.0M |
Member count uses your alliance's member roster (not active attackers) divided by 10, clamped to a 0.5× floor. So 5 members and 1 member both fight the same HP — the formula doesn't punish micro-alliances further than half scaling.
Comp recommendations
Assault weakness means damage output matters more than evasion or sustain. Three comp archetypes consistently clear Ancient Dragon when the alliance level supports them. Pick whichever your roster builds out closest.
Burn-stack DPS
- 2× Striker archetypes wearing Charity (rarity 5 Virtue)
- 1× Healer for sustain through the phase 2 windup
- Sword or Bow starters as filler if Strikers are scarce
The Charity essence's 20% burn application plus +22% damage-vs-burning loop is exactly what an Assault-weakness boss eats. Stacking two Strikers means you almost certainly have the dragon burning by action 3.
Joy-opener burst
- 1× Caster wearing Joy (guaranteed first strike + 30% gauge)
- 2× high-ATK members of your choice
- 1× CC member (Surge for STUN or Rime for FREEZE)
Joy's guaranteed-first-strike-plus-gauge opening means you land an ability before the dragon's phase 2 setup completes. Pairs well with CC to extend the window. Higher ceiling than burn-stack, but more dependent on having a level-Iron+ Joy.
Curse-spread comp
- 1× Caster wearing Faith (CURSE + spread)
- 2× Strikers piling on cursed damage
- 1× Healer keeping the Caster alive long enough to seed CURSE
Less effective than burn against pure single-target (which Ancient Dragon is) but the +20% damage-vs-cursed amp still pulls weight. Best if Faith is your highest-rank Virtue and you don't have Charity or Joy at scale yet.
Common reasons you lose
- Bringing a Defend or Outmaneuver comp. Ancient Dragon is weak to Assault. A defensive comp will survive every phase and lose on the timer anyway because you can't dent the HP bar fast enough.
- Spawning before your alliance has the level. At alliance level 1-3 the HP is technically lower than Void Behemoth's base, but the comp depth that Ancient Dragon punishes is the same. Save the spawn for L5+.
- Burning both weekly spawns on Ancient Dragon. If you fail the first attempt, the second has the same spawn cost and probably the same outcome. Better to drop to Void Behemoth or Titan Guardian for the second spawn and bank a guaranteed clear.
- Not coordinating attack windows. Two weekly spawns and the boss lapses on timer — uncoordinated attacks waste the window. Schedule a 24-hour push and have committed members in.
When to skip Ancient Dragon
Honest answer: when you're not going to win it. The math on rewards looks tempting (4× Iron Colossus) but a failed Legendary attempt yields 0.7× of nothing, while a successful Iron Colossus clear yields 1.3× × 50,000 gold = 65,000 gold reliably. Cycle back to Ancient Dragon when:
- ·You have at least one member with a rank-Iron+ Charity or Joy
- ·Your alliance can field 6+ attackers in the spawn window
- ·You've cleared Void Behemoth once at your current alliance level (good signal)
The "right" time to push Legendary is a deliberate decision, not a streak chase. The reward gap survives until next week's spawn cap; it'll still be there.
FAQ
What is Ancient Dragon's actual HP at my alliance level?
Apply the formula: 2,000,000 × (1 + alliance_level × 0.15) × max(member_count / 10, 0.5). A level-10 alliance with 10 active members fights 5M HP. A level-1 alliance with 5 members fights 1.15M HP. The picker in-game shows the same number — trust it.
Why is the weakness 'Assault' and what does that mean?
Assault is one of three combat approaches a boss can be weak to (alongside Outmaneuver and Defend). Ancient Dragon takes more damage from comps that prioritize raw damage output over evasion or sustain. Practical read: bring your highest-ATK members, not your safest ones.
What's the reward for clearing Ancient Dragon?
200,000 gold, 400 gems, and 2,000 essence dust at the neutral 1.0× multiplier — multiplied by 1.3 on a win and 0.7 on a loss. That's 260,000 gold, 520 gems, 2,600 essence dust on a clean kill. Four times the Iron Colossus payout for roughly the same alliance time investment if you can actually clear it.
Should we even try Ancient Dragon at low alliance level?
Honestly, no. A level-3 alliance fights 1.45M HP per the formula — technically lower than Void Behemoth's 1.5M base, but the Assault weakness gating still applies and a sub-level-5 alliance probably can't put enough committed damage into the window. Use your two weekly spawns on bosses you'll actually finish.
Does Ancient Dragon have a phase progression?
Yes — phase preferences [2, 1, 0] per the server template, meaning the boss prefers phase 2 (typically the most aggressive) before cycling down. Phase data is server-authoritative and lives on the bosses reference; the actual mechanics shift slightly between patches, so trust the in-game tooltip over a static description.
