Omega Infergon Boss Guide - Russet Highlands

The armoured dragon of Russet Highlands

Omega Infergon is the Omega boss of Russet Highlands — one of the three quest-gated weekly challenges documented in the launch build (the world bosses overview covers the whole system). Its base creature, Infergon (NO.067), is a Fire-element DPS with 505 total attributes and ATK 125 per the official companion wiki; the Omega encounter is the boss-scale version of that kit.

Unlocking the fight

Omega bosses have no spawn timer — the encounter activates only after you complete its unlock condition (per community documentation of the launch build’s map data, quest names from beta tooltips):

The kit you are fighting

The boss script is not yet documented on the live build; the official Aniilog page for Infergon lists the kit it is built from, and three mechanics stand out tactically:

• Projectile reflection — Gale Charge reflects incoming flying projectile attacks mid-charge. Ranged teams get their own damage back; plan melee or non-projectile damage.
• Fire Debuff stacking — Lava Breath and its aerial breath (Hot Breath, power 168) each apply 8 stacks of Fire Debuff, and its trait adds +30% damage against targets holding 5+ stacks. Sustained fights snowball against you — burst it down.
• Charge-and-shield — Fiery Charge grants a shield worth 5% max HP on hit, and both charges dive out of flight.

Team preparation

• Elements: Fire defender — bring Water or Earth damage (1.6x), and expect Fire, Grass, and Ice to be resisted (0.625x). The full grid is in the type chart.
• BREAK coverage: its BREAK stat is modest (50) on the base creature — shields, not the health bar, are usually the Omega gate; the Twine guide’s BREAK forms list launch-verified options like Inferlupa (BREAK 108).
• Ranged caution: between projectile reflection and charge pressure, a melee-physical or homing-free composition handles this fight better than a pure sniper team.

Rewards

Omega first clears are positioned as the weekly-limited payoff of the tier, with richer boxes at higher documentation levels — specific drop tables are being documented from the live servers and land here with the page’s last-verified date. The full tier structure and the other two Omegas (Omega Sherro, Omega Tuckin) are one click away in the overview.
