Bjorn and Bastigor sit at the top of Feybreak Tower as the game’s toughest faction duo, and their Hard Mode version turns an already tanky fight into a race against a five-minute timer. The winning approach leans on a Fire-and-poison Pal that heals itself while a launcher does the heavy lifting.
Quick answer: Bring a level 80 Felbat with Life Steal Lv. 5, set it to defensive so it keeps applying poison and burn, buff with Mammorest Curry, then fire a Drone Launcher and Multi Guided Missile Launcher at Bjorn on Bastigor’s back. Poison plus burn plus the launchers clears the fight in a little over two minutes.
What you need before the fight
Hard Mode Towers only open after you defeat all eight faction leaders in Normal Mode, from Zoe through Auri. Zenara is not required to unlock them. You can start Hard Mode even with story objectives still open, since the only gate is clearing each boss once.
Feybreak Tower sits on the southwestern edge of the map near Frozen Coral Hill, around coordinates -1294, -1669. The approach is freezing, so equip cold-resistant gear such as Cold Resistant Hexolite Armor along with an Advanced Shield and Hexolite Helmet to survive the ice attacks.
Push both your character and your carry Pal to level 80 and condense that Pal to four stars for the extra stats. Do not bring Ice-type Pals. The arena is already cold, and summoning one drops the temperature further, which starts damaging you.
Hard Mode changes to Bjorn and Bastigor
Hard Mode raises the level, adds allies, shortens the clock, and gives the boss new attacks. Bastigor is still an Ice-type that is weak to Fire, and Bjorn still rides on its back, where a hit counts as a critical.
| Aspect | Normal Mode | Hard Mode |
|---|---|---|
| Boss level | 60 | 80 |
| Time limit | 10 minutes | 5 minutes |
| Allies | None | Level 70 allies that cannot be caught |
| Attacks | Standard kit | New AoE and tracking attacks that can one-shot |
| First-clear reward | 5 Ancient Technology Points | Bjorn Hat, Training Crystal, schematic chance |
The normal boss already has around 509,000 HP, and the Hard Mode version scales well past that. The level 70 allies that spawn at the start hit hard on their own, so invest in your own defenses rather than relying on Pals to soak everything.
The Felbat life-steal build that cleared it
The core of the strategy is a level 80 Felbat carrying Life Steal Lv. 5 as its Partner Skill, which restores 9% of the damage it deals back as health. Paired with survival passives, it stays alive through the fight and keeps stacking status damage without any input from you.
| Slot | Setup |
|---|---|
| Partner Skill | Life Steal Lv. 5 (9% of damage dealt as health) |
| Active Skills | Poison Fog, Fire Ball, Flame Funnel |
| Passive Skills | Diamond Body, Immortality, Legend, Serenity |
Poison Fog stacks poison while Fire Ball and Flame Funnel apply burn, and Fire is Bastigor’s weakness. The Immortality and Diamond Body passives keep Felbat standing while it ticks damage, and Life Steal continuously tops it off. Setting the Pal to defensive keeps it focused on applying those effects instead of chasing the boss into danger.
Weapons, accessories, and food
Your own damage comes from two launchers. The Legendary Drone Launcher deploys drones that fire passively, and the Rare Multi Guided Missile Launcher throws out guided missiles that track the boss. Together they let you deal damage even while you are focused on staying alive.
| Item | Type | Note |
|---|---|---|
| Drone Launcher | Legendary | Attack 240, deploys passive drones |
| Multi Guided Missile Launcher | Rare | Attack 7375, guided missiles |
| Dogen Emblem | Epic | Accessory |
| Silvegis Emblem | Epic | Accessory |
| Warsect Terra’s Belt | Epic | Accessory |
| Attack Pendant | Rare | Accessory |
| Mammorest Curry | Epic | Attack buff for you and Felbat |
Eat the Mammorest Curry before you engage so both you and Felbat start the fight with boosted attack. Bring Advanced Recovery Meds and Revival Potions as backup in case the opening allies catch you out.
How to fight Bjorn and Bastigor
Bastigor’s dangerous moves are the ones that freeze you in place, such as Lord Of Ice and Jumping Cold Smash. Watch the ground markings and sprint clear before they detonate, since being frozen usually means eating the follow-up hit.
Rewards and how to confirm the clear
You know the fight is won when the BOSS ELIMINATED notification appears. Check your inventory for the Bjorn Hat, which is guaranteed on your first clear, along with a Training Crystal for leveling Pals.
Hard Mode also has a 10% chance to drop the Legendary Lightweight Ancient Armor schematic. Craft it at a Workbench or Assembly Line while the schematic sits in your inventory.
Why the fight fails
- Running out the five-minute timer before the boss falls, usually from too little damage output.
- Getting one-shot by the level 70 opening allies or the new Hard Mode AoE attacks.
- Bringing an Ice-type Pal, which drops the arena temperature and damages you.
- Getting frozen against a wall or the arena edge, leaving no room to dodge the follow-up.
Once the build is set up, most of the fight runs on its own. Keep the poison and burn stacks live, punish Bjorn on Bastigor’s back, and the clock stops mattering long before it runs out.
