Strategic Analysis

Tactical Identity

The Siege Onager is the **game-ending splash weapon**. Few things survive its impact, making it the ultimate counter to massed armies.

Tactical Playbook

Army Wiper

One Siege Onager shot can kill 10+ Arbalests. The psychological pressure alone forces enemies to spread formations inefficiently.

Cut Trees Strategically

Use attack-ground to open paths through forests. Create flanking routes or deny enemy escape paths.

Defensive Anchor

A Siege Onager behind your wall acts as area denial. Enemies cannot mass units to attack without getting obliterated.

Critical Point

**Extreme friendly fire risk**. At 75 damage with huge splash, one misclick kills your own units. Use attack-ground commands and position your army carefully.

Understanding The Stats

The Siege Onager is rare and expensive but unmatched in area destruction. A game-changer when available.

Devastating Attack

75 Attack

One-shots most units in the blast radius. Grouped archers evaporate.

Massive Splash

0.75 Blast Radius

Largest splash in the game. Covers more area than any other siege.

Expensive Upgrade

1450F 1000G

Very costly but worth it. Changes the dynamic of late-game fights.

Limited Access

13 Civs Only

Rare upgrade. Having it is a significant advantage over enemies without it.

Coach's Tip

Your 70 HP is still low for such an expensive unit. Protect your investment - losing a Siege Onager is losing 1450 food and 1000 gold plus the base cost.
