ELHEXA CodexEpic Battle 2026 Q4 — Invasion of the Stars
The fourth epic battle arrives from beyond the stars. Vexa Ra-Syn, Weapon Zero — a living weapon that erased her own world — has locked her sensors onto ELHEXA. Beside her stands her creator, Tyren Or-Vek, the Genesis Directive, shielding the weapon he cannot bring himself to destroy. Fight the Invasion of the Stars, earn Celestial Starshards, and recruit both twins as playable adventurers.

How to Access
A Battle Unlike Any Before — Two Bosses, One Target
For the first time, you face two bosses on one field — and the rules of victory change with them. Watch the identity marks above their HP bars:
Vexa carries the Victory Mark — defeat her and the battle is won on the spot, no matter what else still stands. She is the invasion’s firepower: a phase-shift railgun, an antimatter blade that tramples the whole line, and a will of iron that shrugs off stun, sleep, silence, and paralysis alike. Damage-over-time still burns her, and she can fall — twice, if her wards are up — before she stays down.
Tyren fights beside her as a full boss — but he never attacks. He heals, shields, and empowers Vexa relentlessly, and his defensive walls make him monstrously hard to put down. You do not need to kill him — but every second he acts, Vexa gets harder to kill. Stun him, sleep him, strip his blessings, or burn him down first: all four are real strategies.
Both twins are god-type beings — the long-dormant god-slaying skills finally awaken. Godslayer Crossbow and Dragon God Reaver deal massively increased damage to them.
Their blessings are not untouchable either: most of what Tyren grants can be dispelled — or outright stolen. And when Tyren falls, nearly everything he granted collapses with him — all but the lethal-blow ward, which lingers once cast.
Battle Stages
Seven stages of ascending fury, each costing 100 energy (the ZERO and PRIME showdowns cost almost none). Repeatable stages drop Celestial Starshards every clear — 5 up to 50 per run as the level climbs.
| Stage | Repeatable | Notes |
|---|---|---|
| I – V (Lv.10 → Lv.200) | Yes | The invasion grows with you — Starshard drops climb from 5 to 50 per clear. |
| ZERO (Lv.200+) | First clear only | The twins at full force. First clear grants the Twin Star Sigil — instantly exchangeable for one UR twin. |
| PRIME (Lv.200++) | First clear only | The true invasion. First clear grants the Twins’ Platinum Trophy — proof you beat the strongest fight in ELHEXA. |
| ZERO / PRIME Rematch | Yes | For glory, not spoils — refight the showdowns anytime after clearing them. |
The Twins’ Arsenal
Know what is coming. The invasion’s core techniques, straight from the battlefield:
| Skill | Carrier | What it does |
|---|---|---|
| Phase-Shift Railgun | Vexa | A piercing railgun burst down a whole line, leaving targets burning. |
| Antimatter Crimson Blade | Vexa | Sweeps ALL allies with Trample Damage — it ignores evasion, invincibility, and resistance. Wounded allies take extra. |
| Triple Shot | Vexa | Relentless volleys at your back line, almost without pause. |
| Iron Will | Vexa | Full immunity to stun, sleep, silence, and paralysis. Damage-over-time is unaffected — it remains your steadiest source of pressure. |
| Perseverance in Peril | Vexa | Survives a fatal blow, then turns briefly invincible. Expect to kill her more than once. |
| Defense Stances I–III | Tyren | Layered team-wide damage reduction as the twins’ health falls — stacking to a near-impenetrable wall. Dispellable, stealable. |
| Eye of the Sun / Well of the Full Moon | Tyren | Sweeping combat and magic empowerments for both twins. Dispellable, stealable. |
| Healing Circle / Final Redemption / City of Clouds | Tyren | Heals, heal-over-time, barriers — and a team-wide ward that lets both twins survive lethal blows. |
