Dungeon Bonuses and Radiation

Battlefield bonuses

Throughout the battlefield you can hold zones that improve your performance in dungeons. Some zones provide a Global Dungeon Boost, which applies to every room type: Battle, Gather, Craft, Explore and the Boss room.

You can also earn specialised bonuses that only apply to specific rooms. A Battle bonus applies to combat and Boss rooms, while an Exploring bonus only affects Explore rooms.

Permanent Dungeon Bonuses

Completing dungeon levels earns permanent Squadron Bonuses, based on the highest level cleared in each dungeon:

The bonus per level is not flat. Early levels are worth much more than later ones:

So clearing Level 5 gives 25%, Level 10 gives 45%, and Level 20 gives 75%.

Radiation

Every 5 rounds, in every room, players take a percentage of their max HP as Radiation damage. Each room type has a different intensity:

• Battle: 8% of max HP
• Gather, Craft and Explore: 5% of max HP
• Boss room: 10% of max HP

In normal dungeons the protection requirement only starts at Level 6, so radiation does no damage below that. In the Stellar Ruins special dungeon it applies from Level 1.

Mitigation

You can reduce this damage by upgrading your Radiation Protection for each specific room type. Each dungeon level raises the protection threshold needed to nullify the damage, and if your protection is lower than required you take proportional damage.

The protection required is:

• Normal dungeons: 12 * (Dungeon Level - 5), which is 0 up to Level 5
• Stellar Ruins: 10 * Dungeon Level

TL;DR:

• Radiation protection is per room type, so check all four.
• The first levels of each dungeon give the biggest permanent bonus, so spreading progress across the four dungeons beats pushing one of them deep.
