|Effect||Battle Elephants +3 attack|
As the Khmer already have faster Battle Elephants, Tusk Swords furthers the offensive capabilities of them. They also have full Blacksmith upgrades for them, plus Bloodlines and Husbandry. If the player is intending to use Battle Elephants for attacking purposes in the early Castle Age, it is really worth the gold cost, and may even be prioritized over Iron Casting; but under normal circumstances, it should be treated as another Blacksmith upgrade and be researched after Iron Casting and Blast Furnace.
Team bonuses Edit
Tusk swords are a pair of blades specifically designed to be attached to elephant tusks. These weapons, combined with elephant body armor, made elephants more fearsome in battle. It is believed that hundreds or even thousands of tusk swords have existed in the past. But today, only few of them remain and can be seen in museums.
