Age of Empires Series Wiki

Chatras is a technology in Age of Empires II HD: Rise of the Rajas that is unique to the Vietnamese and can be researched at the Castle. Once researched, it gives +100 HP to Battle Elephants.


The value of Chatras is that it makes the Battle Elephants highly resilient, and for a civilization like Vietnamese that requires support for their archers from other troops, having a tanky unit is a great advantage, as Battle Elephants can act as meat shields that guard the ranged units. A fully upgraded Elite Battle Elephant with both Bloodlines and Chatras researched will have 420 HP, a value that is only beaten by the normal War Elephant (470 HP) and the Elite War Elephant (620 HP).

Team bonuses[]

  • A team containing Berbers: With Kasbah researched, researching Chatras is 25% faster.


Rise of the Rajas[]

  • Initially, Chatras gives Battle Elephants +30 HP. With patch 5.7, Chatras now gives +50 HP.

Dawn of the Dukes[]


A Chatra (Sanskrit: छत्त्र, Hindi: छत्र, lit. "umbrella") is an ornament with special cerimonial and symbolic valour to Hindu, Jain, and Buddhist traditions. It was and is used as royal regalia in Thailand. It doesn't seem to have had a practical use in battle.
