Blast siege. Deletes clumped archers and Scorpions. Friendly fire is real.

What it does

Drop one behind your army vs archers or Scorpions. Micro the shot. Do not fire through your own Knights.

Strengths

  • Area damage.
  • Beats Scorpion packs if it fires first.
  • Cuts trees (Onager and up).

Weaknesses

  • Friendly fire.
  • Cavalry.
  • Minimum range.

Strong counters

Strategic advice built on verified armor classes and unit access. Not unconditional.

  • Knight · cost-effective · can win in equal numbers

    Cavalry dive is the default. BBC is the Imperial siege answer.

    • Pikes next to the Onager.
    • Celt fire rate can punish a slow charge.
  • Scout Cavalry · cost-effective · needs numbers, surround, or micro

    Hussars are the cost-effective dive.

    • Halberdiers.
    • Mangudai sniping from outside.
  • Bombard Cannon · cost-effective · can win in equal numbers

    BBC outranges Onagers.

    • Not available for Khmer, Britons, Mongols, or Celts in this set.

Situational counters

None published in this category yet.

What it counters

  • Scorpion

    Onagers one-shot clumps. If both packs fire, the wider blast usually wins.

  • Ballista Elephant

    Onagers hit the clump. A single Onager does not beat a dozen elephants.

  • Archer

    One Mangonel shot can pay for itself against a clump. Equal numbers of Mangonels vs archers is the wrong framing.

  • Spearman

    Blast vs a pike clump. Overkill if you already have archers.

  • Longbowman

    Onagers punish the clump that Longbows like to stand in.

  • Hand Cannoneer

    Onagers delete the clump. Micro required.

Why matchups work

High melee blast vs low-HP clumped units. Scorpions have low HP. Cavalry outrun the projectile and crush the Mangonel.
