Beasts you capture and raise at the Beast Cage. Each has an active skill you trigger when it helps most.

**TL;DR:** Level pets in the order the game unlocks them, fire the right skill before the right moment (Hyena before construction, Lion and Tiger before fights), and save Wild Marks for SvS.

## Key facts

- **Unlocks:** Furnace 18, around server day 55
- **Building:** Beast Cage
- **New pets:** Every few months of server age
- **Skills stack:** Yes (official help center)

## When pets arrive

| ~Server day | Pets |
| --- | --- |
| 55 (Furnace 18) | Cave Hyena, Arctic Wolf, Musk Ox |
| 90 | Giant Tapir, Titan Roc |
| 140 | Giant Elk, Snow Leopard |
| 200 | Cave Lion, Snow Ape |
| 280 | Iron Rhino, Saber-tooth Tiger |
| 370 | Mammoth |
| Later | Frost Gorilla, Frostscale Chameleon |

Note: Per a community server timeline. You also need the previous pet in the chain at a set level (Lv.15 or Lv.30) before the next can be captured.

## Active skills

| Pet | Skill effect |
| --- | --- |
| Cave Hyena | Construction speed +5–15% (5 minutes) |
| Arctic Wolf | Restores Chief Stamina |
| Musk Ox | Speeds up gathering (instantly finishes a resource tile) |
| Giant Tapir | Finds pet food |
| Titan Roc | Reduces enemy troop health |
| Giant Elk | Finds items, including Charm Designs |
| Snow Leopard | Faster marches, lower enemy lethality |
| Cave Lion | Troop attack +2.5–10% (2 hours) |
| Snow Ape | Deployment capacity +3,000–15,000 (2 hours) |
| Iron Rhino | Rally capacity boost (2 hours) |
| Saber-tooth Tiger | Troop lethality up to +10% (2 hours) |
| Mammoth | Troop defense up to +10% (2 hours) |

Note: From community guides; effects scale with pet level and the numbers may change with updates. Different pet skills can be active at the same time.

## Leveling & refinement

- Level pets with **pet food**. Every 10 levels a pet needs an **advancement**, which costs extra materials: Taming Manuals from Lv.10, Energizing Potions from Lv.30 and Strengthening Serums from Lv.50.
- Higher-rarity pets have higher level caps, up to Lv.100 for the top pets (per one wiki).
- **Refinement** uses Common or Advanced Wild Marks to roll extra stats. A roll can come out worse, so keep the old stats if it does.
- One wiki lists pet adventures at 10 Chief Stamina and 4 hours each, for random rewards.

## When to fire which skill

- **Cave Hyena** right before starting a big build, especially on SvS City Construction day.
- **Musk Ox** on gathering-scoring days.
- **Cave Lion**, **Saber-tooth Tiger** and **Mammoth** right before a rally, garrison fight or Bear Hunt.
- **Snow Ape** and **Iron Rhino** for rally leaders who want bigger marches.
- On [SvS](https://wos.sheet.guide/guides/events/state-vs-state.md) Beast Slay and Power Boost days, Wild Marks and pet advancements score well (an Advanced Wild Mark is worth 15,000 points), so save them.
