When you join someone else’s rally or reinforce a garrison, one hero skill of yours can boost the whole group. Picking the right one is one of the cheapest power gains in the game.

**TL;DR:** Put **Jessie** (or Jasser/Jeronimo) first when joining attacks, **Patrick** or **Sergey** first when reinforcing, and level that hero’s **first expedition skill**, not their stars.

## Key facts

- **Slot that counts:** Your first march slot
- **Skill that counts:** First expedition skill
- **Best attack buff:** +25% damage (max level)
- **Garrison picks:** Patrick, Sergey

## The rules

When you **join** a rally, only the hero in your **first march slot** contributes, and only their **first expedition skill**. Your second and third heroes add nothing.

Only a few joiner skills apply per rally, and **higher skill levels get priority**. One guide puts the limit at four.

One guide claims joiner skills don’t apply at all; most guides and players disagree. Compare battle reports if you’re unsure.

## Attack joiners

| Hero | Rarity · class | First expedition skill | At max level |
| --- | --- | --- | --- |
| **Jessie** | Epic · Lancer | Stand of Arms | +25% damage dealt by all troops |
| **Jasser** | Epic · Marksman | Tactical Genius | +25% damage dealt |
| **Jeronimo** | Gen 1 Mythic · Infantry | Lone Wolf | +25% damage dealt |
| **Seo-yoon** | Epic · Marksman | — | +25% troop attack |

Note: One guide treats “damage dealt” and “attack” as separate modifiers, so Seo-yoon can stack alongside a damage joiner in the same rally.

## Garrison joiners

| Hero | Rarity · class | First expedition skill | At max level |
| --- | --- | --- | --- |
| **Patrick** | Epic · Lancer | Super Nutrients | +25% troop health |
| **Sergey** | Epic · Infantry | Defenders’ Edge | −20% damage taken (4% at level 1) |

Note: One guide says Patrick’s skills also add attack; others list health only. Some later-generation heroes have defensive first skills too, so compare exact skills before replacing these two.

## Where it matters

- [Bear Hunt](https://wos.sheet.guide/guides/battles/bear-hunt.md): join every rally with an attack joiner first. It’s the clearest win.
- [Sunfire Castle](https://wos.sheet.guide/guides/battles/sunfire-castle.md), [Fortress Battles](https://wos.sheet.guide/guides/battles/fortress-battles.md) and [Foundry](https://wos.sheet.guide/guides/battles/foundry-battle.md): attack joiners for rallies, garrison joiners for reinforcing held buildings.
- Reinforcing a teammate’s city or the alliance HQ: lead with Patrick or Sergey.

## Building a joiner

- **Jessie** is usually the easiest to max, so most players start with her.
- Spend **expedition skill manuals** on the joiner’s first skill. A maxed first skill beats extra stars.
- Before you join, check who’s in your first slot: an attack joiner for rallies, a garrison joiner for reinforcing.
