To clear Chapter 12 Stage 7 of the Frost Fortress campaign in Armada: Warships Legends, you must defeat the Ghost Fleet flagship, Super Warship Hela. Success requires turning off full auto-combat to manually direct burst damage, deploying heavily armored frontliners to absorb concentrated artillery, and eliminating flanking escorts before burning Hela down during her final phase.
Boss Mechanics: Super Warship Hela
Hela relies on reinforced armor and high-caliber salvos to wear down your fleet through sustained attrition. Auto-firing skills indiscriminately will waste your heavy ordinance on her damage-reduction windows or low-value screening ships.
| Boss Mechanic | Incoming Threat | Tactical Response |
|---|---|---|
| Main Battery Barrage | High kinetic and explosive damage aimed at primary targets | Absorb using vanguard battleships equipped with defensive shielding |
| Long-Range Torpedo Volley | Broad-lane burst damage targeting fleet formations | Maintain formation discipline and intercept using screen positioning |
| Ghost Escort Ships | Sustained flanking chip damage that redirects auto-targeting | Clear immediately with secondary batteries or light airstrikes |
| Overdrive Phase | Increased attack speed and higher damage output at low health | Focus all manual flagship and carrier burst skills directly on Hela |
Fleet Composition and Role Distribution
Surviving Stage 12-7 requires balancing high single-target penetration with defensive sustain. Pure offensive fleets will collapse under Hela's opening salvos before dealing decisive damage.
- Frontline Vanguard (Battleships / Armored Cruisers): Equip maximum hull enhancements and damage-reduction modules. These ships must absorb Hela's primary battery fire and block torpedo spreads from reaching fragile support hulls.
- Midline Support (Repair and Defense Buffers): Bring dedicated support vessels capable of active fleet repair. Natural hull regeneration cannot keep pace with the incoming damage, making manual repair pulses essential for keeping your vanguard alive.
- Backline Strike (Heavy Carriers / Torpedo Warships): Dedicate rear slots to single-target burst damage. Prioritize armor penetration and critical strike chance over wide-area spread attacks, ensuring all damage connects with Hela's armored hull.
Step-by-Step Battle Strategy
Execute the encounter manually using the following tactical sequence:
- Eliminate Initial Escorts: Clear the Ghost Fleet support ships flanking Hela as soon as the battle starts. Use secondary guns and light airstrikes to remove them quickly so your capital ships do not waste targeted attacks on minor targets.
- Hold Tight Formation: Prevent fast destroyers or light cruisers from rushing ahead into Hela's primary firing arc, where isolated ships take lethal spike damage.
- Pre-cast Defense Buffs: Trigger fleet-wide defense shields right before Hela unleashes her first coordinated battery and torpedo barrage to protect your repair ships.
- Unload Coordinated Burst Salvos: Once Hela's opening defensive cycle lapses and the screen is clear, fire your carrier strikes, torpedo salvos, and flagship abilities simultaneously.
- Burn Hela in Overdrive: When Hela reaches her critical health threshold, her skill cooldowns accelerate. Ignore any late-spawning escort distractions and direct all remaining manual attacks straight into Hela to finish the fight before fleet attrition overwhelms your frontline.
