Titan Challenge

The three Titans

The client ships three Titan bosses, rotated by the server between rounds. Each is a dedicated stage with a single boss wave — same 6-minute format, different barrage patterns (Arachne's arena adds a sandstorm).

The HP ladder

The boss framework (boss_property_levels) defines 20 boss levels. The server picks the level; each step roughly ×2–5s the previous HP pool. Level 1 is already 100 million — by level 20 the bar is 62.5 quadrillion. This is why the mode is a damage race, not a kill attempt.

Anatomy of one attempt

Every attack costs 5 Energy + Stargate Challenge Tickets (tickets reset daily and do not carry over; the per-day allowance is a server value). The fight itself is two phases:

Phase 1 · 60sNormal bullet-hell. The barrage is dodgeable — dodge-triggered bonuses (Phantom Dog, Howler) can proc here.

Phase 2 · 300s "Frenzy State"The Titan unleashes an undodgeable full-screen barrage until the countdown ends. You cannot avoid this damage — you out-heal and out-tank it. Dying costs DPS uptime, so survivability is throughput.

The in-game "Frenzy State: {timer}" banner is this phase-2 countdown (titan_challenge_time2 = 300). Each completed run also feeds ~95 Battle-Pass EXP (battlepass_Titan_convert_exp).

The season structure

A season is 12 rounds × 7 days = 84 days (the Titan Shop resets on the same 84-day clock). Active players are auto-enrolled each round:

DAY 100:00 UTC+8 — players are bucketed into 50-player groups by tier. Bronze → Legend, seven tiers.
DAY 1–7A fixed number of attacks per day. Total damage accumulates for the round — every attempt counts, there is no "best run only".
DAY 723:00 UTC+8 — a 1-hour final tally. The Titan can't be challenged; a run that ends inside the tally window scores zero.
RESETRankings promote/demote you, ranking rewards arrive by mail, next round begins. Deal 0 damage and you're unranked, unrewarded, and demoted one tier.

The last round of a season pays ranking rewards only — no tier rewards. Reaching Silver+ each season also pays a one-time tier reward (table right).

Tiers, promotion & season tier rewards

What it pays

Three separate faucets: a per-attempt damage milestone track, a weekly ranking payout inside your 50-player group, and the one-time season tier rewards above. Milestones pay Stars + Honor; rankings pay Stars + Titan Coins (the Titan Shop currency, an unnamed item in the loc table — item #67).

Maximizing damage — the full modifier stack

Ranked from "this decides the leaderboard" downward. The headline: the Titan has a rotating weakness worth ×1.5 damage, the matching gear set adds two more attack multipliers on top, and a surprising amount of permanent boss-damage % is sold inside this mode's own shop.

1 · Hit the weakness — 150% damage

Each round's Titan has a published weakness (the "Clue" panel in the lobby): "When the fighter transforms into the [featured] Robot, it can deal 150% damage to the Titan." Transforming requires equipping all five pieces of that round's featured gear set (fighter + maingun + winggun + missile + armor). The featured set rotates server-side (titan_weakness_param); check the clue before you build. This single flag is a ×1.5 on everything you do.

2 · The set itself is two more buffs

The transformation sets double-dip: 3 pieces = attack of all weapons +15%, and at 5 pieces you can transform mid-run, which raises the attack of all equipped gears by another +30%. So the featured-set pilot fights with +15% → transform → +30% gear attack → ×1.5 vs the Titan. The five sets are below; all are premium chest gear (see Gacha — Titan Chest, opened with Titan Keys).

The five transformation sets

Budget versions exist: SR fighters Starscream ("convert into Starscream Titan, winggun attack +20%") and Jetfire ("missile attack +20%") carry a built-in convert skill without needing a 5-piece set — weaker, but obtainable without the collab chests.

3 · Mech Spirits — permanent damage%, sold in the Titan Shop

The Mech Spirit collection (45 fusable units, internally intelligence) is the biggest source of always-on damage multipliers — and their shards are what the Titan Shop sells, making this mode self-reinforcing. The ones that matter for a Titan run, with values at skill level 1 → max:

Reading the table: "Saturation Fire" (damage while enemy HP is above 60%) is effectively a permanent buff here — you will never push a Titan below 60%. The plain-R spirit Fireball is the only direct "damage vs Boss" stat in the game and costs pocket change in this shop. The survivability rows are phase-2 throughput: you can't dodge the Frenzy barrage, you can only out-mitigate it.

4 · Pilots that scale with the mode

Three SR Pilots' accumulate skills feed on Titan participation itself — they get permanently stronger every week you show up (full mechanics on the Pilots page):

5 · The in-run draft

Titan stages draw from the standard roguelite draft pool (group 107 — same weapon-advance/special cards as the campaign, no titan-exclusive cards). Six minutes is long enough to assemble a full build: prioritize maingun/winggun/missile advance cards for your strongest weapon line, then specials. The full draft system is on the Combat page.

6 · Uptime is a multiplier

Phase 2 is 5 of your 6 minutes and it is undodgeable by design. Deaths and near-death downtime cut directly into total damage. Stack HP/defense, healing enhancement, and "final damage decrease" (Aqua Spirit, Berserk Dragon) — and note Lancelot's crit-damage-reduction stacks exist precisely for this fight.

7 · The permanent attack stack (where to actually spend)

Everything that raises your attack sheet raises Titan damage — the fight uses the normal damage pipeline (attribute formulas) with the weakness ×1.5 on top. The checklist, in rough order of impact per resource:

Discipline beats heroics: damage is cumulative per round and tickets don't bank — a missed day is damage you can never recover. Burn every attempt, every day, even with a weak roster: milestones pay per attempt, participation feeds the three Titan Pilots, and 0-damage rounds demote you.

Strategy — the best loadout against each Titan

Everything below is crunched from the game's unit tables (batch_factory and the ent_prop stage configs) and cross-verified — no guessing. The headline: the Titans have no elemental resistances and zero defense (the def field is 0 on all 47,129 unit rows in the game), so "best equipment" isn't about counters — it's about which of your damage lines legally apply to each boss, and how many hitboxes you can touch at once.

Atlas

SINGLE TARGET

BranchesAerial + Boss (unitBranches [1,3])

Hitboxes1 main + a half-HP part (same ATK) + a negligible third

Stackevery vs-aerial line on top of the boss lines: Legion Tech #26 vs aerial +30%, plus all universal boss lines below

BuildPure single-target focus. Multi-hit spread is wasted here — concentrate maingun/missile output and burn stacks on the one body.

Arachne

14 HITBOXES

BranchesGround/Sea + Boss (unitBranches [2,3])

Hitboxes14 part-units, each with the FULL HP pool (ent_prop9 ids 211101–14) — and she hits 1.2× harder than Atlas

Stackvs-ground/sea lines: Legion Tech #25 vs ground & sea +30% — the cheapest damage ladder in Legion Tech — plus the boss lines

BuildPiercing / AoE / multi-hit + DoT spread. Anything that hits or ticks per-target can pay out up to ×14 here. Bring more mitigation for phase 2.

Kraken

SERVER-SIDE

BranchesGround/Sea + Boss (batch_factory 301003)

HitboxesUnknown — Kraken ships no client-side stat rows or asset bundle; its numbers arrive by hot-update

Stacksame paper profile as Arachne: vs-ground/sea +30% + boss lines apply

Buildrun the Arachne damage-line package; treat body-count and barrage as unknowns until you've seen the fight.

The universal damage stack, in order

These apply to every Titan, biggest lever first — each is a separate multiplier bucket on the same hit:

Weakness transformation

×1.50

Boss lines (Legion #29)

+30%

Branch line (#25/#26)

+30%

Fireball spirit (vs Boss)

+24.3%

Camp Top tech (boss dmg)

+13.5%

Drone "Overload Strike"

+10.5%

Values at max investment, from guild_tech, camp_tech_lv, intelligence and drone_passive_library (L7 recast). Dragon Emperor's +77% while enemy HP > 60% is effectively permanent here too.

Why drones — the verified triple-dip

The attack formulas inject the summed attack of all three deployed drones at 100% into maingun, winggun AND missile simultaneously (drone_conf atk_ratios [0,1,1,1] → the atk#drone1–3 terms in every weapon algo). No other system triple-counts. Three endgame drones ≈ 66,500 attack added to every weapon line at once (Lv200 base 5,040 × ★35 +340% ≈ 22,200 each). And drones are deliberately PvE-strength: their outgoing damage ratio is 1.0 in PvE vs 0.025 in PvP (drone_base atk_out_ratio).

Why burn — the verified DoT

Burn-drone actives apply Burning: 70% damage per second per stack, max 6 stacks (drone_skill 9071+, battle_buff 90712: 1s tick, 5s duration). Three burn drones on ~3s cycles hold a stationary Titan near the cap — ≈420%/s of sustained tick damage before amplifiers. Then the burn-only web stacks on top: Sagittarius +25% burning damage taken per stack (to +150%), drone recast Burning Boost +14%, Magic Armor +23.2% / Stargazer +19.4% burnUp spirits, Star Envoy's 3-burn-drone proc, and burnUp lines on chips and sentinels. Electric's best is Draco's ×3.7 self-amplified burst — real, but with no sustained channel it loses to burn on a 6-minute stationary boss. The 6-minute format is the ideal DoT target.

What's verified, what's refuted, what's server-side

CONFIRMEDZero defense & no elemental resistances on any enemy; the branch profiles above; the drone triple-dip and PvE ratio; the 70%/s ×6 burn mechanics; Arachne's 14 full-HP parts (each worth full damage credit — no exclusion flag exists). REFUTED"Pick Physical Resistance vs Atlas / Energy Resistance vs Arachne" — the units' elementType is a body/skin classification; all Titans deal composite type-3 damage. No phys/energy matchup rule exists in the client. Don't chase elemental counters. UNKNOWNWhether all 14 Arachne parts are exposed simultaneously and hold independent burn stacks (engine-side — if true, burn drones are dramatically better vs her); any server-side def/burn-resist tuning; exact per-weapon emitter rates. Flagged rather than guessed.

The Titan Shop

Paid in Titan Coins from rankings and tier rewards; stock resets every 84 days — one full season, so budget across the whole season, not per week. The big-ticket items are Pilot Training Guides and Mech Spirit shards (including the exact spirits that boost this mode). Entries the client can't resolve are server-rotated chests.

The Transformers twin: Resist Unicron

The collab event Resist Unicron (internally emperor / boss_combat) is the same machine re-skinned: 50-player groups, weakness parameter, damage milestones — but a 5-tier ladder (Warrior → Pinnacle) paying Cybertron Medals and Leader Tokens, with the "Lord of Cybertron" avatar frame at the top. If you learn the Titan Challenge, you already know how to play it.

Fair-play enforcement

The server sanity-checks scores: the config carries a damage_checking threshold of 10¹³, damage submitted during the tally window is voided (error 9005), and confirmed manipulation voids the whole round's damage:

"Due to your cheating behavior during Titan Challenge, this damage is invalid. Your damage dealt in this round … has also been annulled. The use of accelerators, plug-ins, or third-party tools to manipulate game data is strictly prohibited."
