Survival Training Stage Guide
Stage 1 "Like Draws Like" Guide
- Watch out for explosions triggered when enemies are defeated
- Use AoE Battle Skills to eliminate multiple Lv40 enemies at once
- Lv15 enemies can be defeated with Basic Attacks alone
Both Lv15 enemies that can be easily defeated with Basic Attacks and Lv40 enemies with higher durability will appear.
Use Basic Attacks to deal with Lv15 enemies, and use AoE Battle Skills to clear multiple Lv40 enemies at once for better efficiency.

Stage 2 "Explosion Practice" Guide
- Industrial Explosives can be thrown without limit
- Throw bombs at enemy spawn locations
- Watch out for fast-moving dogs
This stage focuses on throwing bombs from high ground at enemies moving along a fixed path.
Keep throwing bombs at spawn points to clear most enemies. For fast-moving dogs, account for the delay between throwing and explosion and aim slightly ahead of their movement.
Stage 3 "Outlast the Bugs" Guide
- Prioritize defeating Acid Originium Slug α
- Take advantage of the enemy-gathering effect after defeating Acid Originium Slug α
If Acid Originium Slug α reaches the Lift Originium in the center, it will trigger a large explosion, so defeat it before that happens. Defeating it will also pull nearby enemies together.
Stage 4 "Coordinated Demolishing" Guide
- Similar to Stage 2
- Keep throwing bombs at enemy spawn locations
- Use damage floors created by defeated Indigenous Pincerbeasts
Just like Stage 2, continue throwing bombs at enemy spawn points. Defeating Indigenous Pincerbeasts (insect-like enemies carrying Originium) creates damage floors that help deal additional damage to other enemies.
Stage 5 "Bad Neighbor" Guide
- Hit Acid Originium Slug with the Axe Armorbeast's charge attack
- After the charge attack hits the slug, finish them with a Final Strike
Acid Originium Slugs are invincible when they first appear, so use the Axe Armorbeast's charge attack to break their invincibility. Once hit, they enter a Staggered state, making them easy to finish with a Final Strike.
Stage 6 "Castle Doctrine" Guide
- Defeat enemies using bombs
- Enemies will spawn from 2 locations
- Be careful not to miss any enemies
This stage also uses bombs, but the layout changes and enemies now spawn from two locations.
It's easier to miss enemies here, so keep an eye on alerts at the top of the screen when enemies approach the supplies.
Stage 7 "Feral Gall" Guide
- Build the Stagger Meter by baiting charge attacks into rocks
- Attack aggressively once the enemy is Staggered
Only one invincible Axe Armorbeast appears. Build up its Stagger Meter by directing its charge attacks into rocks, then go all-in once it becomes Staggered to defeat it.
Stage 8 "Final Assessment" Guide
- Hit the Axe Armorbeast's charge into the Acid Originium Slug twice
- First hit removes invincibility → Second hit defeats it - Clear within 2 minutes to earn a Trimmed Medal
Similar to Stage 5, use the Axe Armorbeast's charge to remove the Acid Originium Slug's invincibility.
This time, the slug has higher durability and cannot be defeated with just a finishing blow, so after removing invincibility, land another charge to secure the kill.
