From T1 recruits to T12 Exalted: what unlocks each tier, how promotion works, and how much each tier is worth in events.

**TL;DR:** Raise each camp separately to unlock tiers, **promote** old troops instead of retraining (you only pay the difference), and time big training batches to land on event days.

## Key facts

- **Tiers:** T1 – T12
- **T10:** Camp level 30
- **T11 Helios:** War Academy (FC5)
- **T12 Exalted:** War Academy FC10

## How each tier unlocks

| Tier | Unlock | Notes |
| --- | --- | --- |
| T1 – T4 | Early camp levels | Each camp (Infantry, Lancer, Marksman) is upgraded separately. |
| T5 | Camp 13 | Troop promotion also opens here. |
| T7 | Camp 19 | A troop passive skill unlocks at T7. |
| T8 | Camp 22 |  |
| T9 | Camp 26 | Needs Furnace 26+, since no building can exceed the Furnace. |
| T10 | Camp 30 |  |
| FC1 – FC10 | Camp Fire Crystal levels (after Furnace 30) | Troops upgrade automatically as the camp’s FC level rises. Passive skills at FC3, FC5, FC8 and FC10. |
| T11 Helios | [War Academy](https://wos.sheet.guide/guides/furnace.md) research | Needs FC5 and Furnace 30. Researched separately per troop type with Fire Crystal Shards. |
| T12 Exalted | War Academy FC10 + Exalted research | Needs that troop type’s T11 Helios unlocked first. Added April 2026. |

Note: The camp levels for T5–T10 come from one community guide (Infantry Camp); verify in-game. The War Academy appears around server day 220.

## Promotion

- Promoting a troop to a higher tier costs only the **difference** between the two tiers, in both resources and time. Your old investment isn’t wasted.
- Promote your low tiers as soon as you unlock a new one, rather than keeping a mixed army.
- On SvS Hero Development day, **promotion scores better than training** new troops, so save promotions for it.

## Event points per troop trained

| Tier | Hall of Chiefs | SvS | King of Icefield |
| --- | --- | --- | --- |
| T6 | 595 | 18 | 11 |
| T7 | 830 | 25 | 16 |
| T8 | 1,130 | 35 | 23 |
| T9 | 1,485 | 45 | 30 |
| T10 | 1,960 | 60 | 39 |
| T11 | 2,520 | 75 | 49 |
| T12 | 2,957 | 94 | 57 |

Note: From one community wiki (WoS Tools). Lower tiers score far less (T1 is 90 / 3 / 1).

## Helios and T12 research

- Helios research has separate **Infantry, Lancer and Marksman** paths. Progress in one doesn’t unlock the others.
- It’s paid in **Fire Crystal Shards**. One tracker lists an exchange rate of 13 shards per 10 Fire Crystals with a 2,600-per-day personal cap.
- Exalted (T12) research adds **+3%** to a stat per level, plus a track for **+600 deployment capacity** per level.
- **Molten** research needs War Academy FC10 and only strengthens T12 troops further. It’s the slowest part of the tree.
