Six pieces of gear worn by your Chief. Each pair boosts one troop type’s attack and defense.

**TL;DR:** Raise all six pieces **within one quality tier of each other** so the set bonuses stay on, prioritise your main troop type, and save upgrades for SvS.

## Key facts

- **Unlocks:** Furnace 22
- **Pieces:** 6 (2 per troop type)
- **Qualities:** Green → Blue → Purple → Gold → Red
- **Set bonuses:** 3 pieces: defense · 6 pieces: attack

## Pieces by troop type

| Troop type | Pieces |
| --- | --- |
| Infantry | Jacket + Pants |
| Lancer | Helmet + Watch |
| Marksman | Ring + Cane |

Note: Each piece adds Attack and Defense for its troop type. Your charms sit in these same pieces.

## Stats by quality (per piece)

| Quality | Attack & Defense | Extra |
| --- | --- | --- |
| Green | +9.35% |  |
| Blue | +17.00% |  |
| Purple | +34.00% |  |
| Gold | +56.78% |  |
| Red | +89.25% | +40 troop deployment capacity |
| Red T6 ★★★ (max) | +255.00% | +1,780 troop deployment capacity |

Note: Base values per one community wiki (WoS Tools). Each quality also has star levels, and Red has sub-tiers T1–T6.

## Set bonuses

- **3 pieces** of the same quality add **defense** for all troop types. **6 pieces** add **attack** for all troop types.
- The bonuses grow with quality, and mixing tiers loses them, so keep every piece **within one tier** of the others.
- In practice: bring all six to the next quality before pushing any single piece further.

## Materials

| Material | Needed for | Where it comes from |
| --- | --- | --- |
| Hardened Alloy | Every tier | Polar Terrors (Lv.3+), beasts (Lv.22+), [Crazy Joe](https://wos.sheet.guide/guides/battles/crazy-joe.md), the [Alliance Championship](https://wos.sheet.guide/guides/battles/alliance-championship.md) shop (1 Badge each) |
| Polishing Solution | Every tier | Crazy Joe, the Alliance Championship shop (100 Badges each) |
| Design Plans | From Blue ★★ | Crazy Joe, limited events, event stores, packs |
| Lunar Amber | Red tier only | Limited events, special content, material exchange |

Note: Maxing all six pieces to Red T6 ★★★ takes about 25.9M Hardened Alloy, 272K Polishing Solution, 48K Design Plans and 6,000 Lunar Amber (per WoS Tools).

## Upgrade strategy

- Prioritise the pair for the troop type you lean on. One guide suggests **Infantry first**, then Marksman, then Lancer.
- Stockpile materials and upgrade in batches during [SvS](https://wos.sheet.guide/guides/events/state-vs-state.md) prep, where each Chief Gear score point is worth points on Power Boost day.
- Crazy Joe and the Alliance Championship are your steady sources, so show up for both every week.
