# Endurance Battles
> Survive monster attacks by actively writing. Earn up to a 4× reward multiplier with the Supremacy bonus system.
Endurance Battles flip the script. Instead of attacking a monster with words, *you* are the one being attacked. Your goal is to **survive by writing continuously until the timer runs out**.
Endurance battles are a great way to "warm up" for the day. Because they challenge you to write continuously, there's not much time to overthink.
> **Where to find it:** Left sidebar → **Adventure** → [**Monsters**](/adventure/adventure-world/monsters) tab (use the **Endurance** filter) [Open in 4TW ↗](https://app.4thewords.com/adventure/monsters)
They appear alongside regular monsters in your adventure areas. Use the **Endurance** filter in the monster list to find them. They're marked with an **Endurance** badge on their card.
Open any document and write normally. Your [Defense stat](/character-and-gear/items-and-spells/battle-items-and-stats) determines your starting defense pool. The higher your Defense, the more hits you can take.
The monster attacks at regular intervals, draining your defense each time. Write continuously to recharge your defense and keep it high. If your defense hits zero, you lose.
The Supremacy system tracks how long you stay in good shape. If your defense stays at 75% or above, your Supremacy builds up each second, and the higher your Supremacy at the end, the better your reward multiplier:
| Supremacy % | Reward Multiplier |
| ----------- | ----------------- |
| 0–32% | 1× |
| 33–65% | 2× |
| 66–90% | 3× |
| 91%+ | 4× |
When the timer hits zero and you're still standing, you win!
Your **Defense stat** is what matters for Endurance Battles, not Attack. Equip gear that boosts your Defense before jumping in.
