## Furnace & City

The Furnace gates almost everything: building levels, troop tiers and new features.

**TL;DR:** Push the Furnace first. Build only the prerequisites its next level asks for, plus the Research Center and troop camps.

### At a glance

- **Furnace** first. Check what its next level requires and build that.
- Then the **Research Center** and your **troop camps**.
- Use your **second queue** for prerequisites, camps and the Embassy.
- After **Furnace 30**, Fire Crystals take over. Bank them from events beforehand.

## Heroes

Gold-tier (Mythic) heroes release in generations as your state ages. Each generation adds an Infantry, Lancer and Marksman hero.

**TL;DR:** Pick **one main hero per troop type** and invest deeply. Spreading shards across many heroes is the most common early mistake.

### Core rules

- One main Mythic per troop type: Infantry Lancer Marksman.
- Build **Jeronimo** early. He’s the usual rally captain for years.
- Joining a rally? Put **Jessie** (or Jasser) in the first slot.
- Save shards when a new generation is close.

## Troops & Formations

Infantry stand in front, Lancers in the middle, Marksmen in the back.

**TL;DR:** Infantry beats Lancers, Lancers beat Marksmen, Marksmen beat Infantry. A 50/20/30 mix is the usual PvP starting point; adjust for the event.

### Counter triangle

- Infantry beats Lancer
- Lancer beats Marksman
- Marksman beats Infantry

### Starting ratios (Inf / Lan / MM)

| Situation | Ratio |
| --- | --- |
| PvP / rallies | 50 / 20 / 30 |
| Bear Hunt (later gens) | 10 / 10 / 80 |
| Garrison | 50%+ Infantry |

## Research

Three main trees: Growth, Economy and Battle.

**TL;DR:** Early: **Growth** (construction and research speed). Add **Economy** when resources are your bottleneck, and push **Battle** once PvP and rallies matter.

### At a glance

- Early: **construction & research speed** in Growth.
- Economy when resources hold you back; **Battle** once you’re fighting.
- Never let the queue sit idle; save research speedups for event days.

## Chief Gear, Charms & Pets

Long-term stat systems that separate whales from everyone else, but F2P can build them too.

**TL;DR:** Raise Chief Gear **evenly**: set bonuses need 3 or 6 pieces of the same quality. Spread charms evenly. Pick pets for the skill you’ll use most.

### At a glance

- **Chief Gear** (Furnace 22): raise pieces evenly for the 3- and 6-piece set bonuses.
- **Charms** (Furnace 25): spread upgrades evenly. Early levels are cheap.
- **Pets** (Furnace 18): level one at a time, picked for the skill you use most.

## Events

Events are where most rewards come from. Know which ones to save for, and which ones stack.

**TL;DR:** Stack effort: use speedups and resources only when **two events score the same action at once**.

### Growth events

| Event | When | Tip |
| --- | --- | --- |
| [SvS](https://wos.sheet.guide/guides/events/state-vs-state.md) | ~4 weeks | Save speedups for prep days; shield on battle day. |
| [King of Icefield](https://wos.sheet.guide/guides/events/king-of-icefield.md) | ~2 weeks after SvS | Only the day’s theme scores. Opens after your first SvS. |
| [Hall of Chiefs](https://wos.sheet.guide/guides/events/hall-of-chiefs.md) | Young states | One theme per day; later replaced by King of Icefield. |

## Alliance Battles

Recurring alliance events. Most are about coordination and attendance more than raw power. Each one has its own in-depth page.

**TL;DR:** Register on time, show up, follow your rally leads, and remember that **Foundry Battle troops recover afterwards**, so fight hard there.

### Must-knows

| Event | When | Remember |
| --- | --- | --- |
| [Bear Hunt](https://wos.sheet.guide/guides/battles/bear-hunt.md) | About every 2 days | **Jessie** in slot 1, Marksman-heavy, join every rally. |

| [Fortress & Stronghold](https://wos.sheet.guide/guides/battles/fortress-battles.md) | Fridays | Hold a building 30 min to take it. Fortresses pay better. |
| [Canyon Clash](https://wos.sheet.guide/guides/battles/canyon-clash.md) | Monthly (Thursday) | Fuel is everything. Don’t waste it. |
| [Sunfire Castle](https://wos.sheet.guide/guides/battles/sunfire-castle.md) | During SvS | Hold 2.5 hours straight to win; contest the turrets. |
