Roman Coins are a type of "currency" earned in the game through Land Battle activities. The Land Battle activities include defeating NPC enemies in the Coliseum in Rome, the various Dungeons throughout the UWO world, and in Landing Zones and Outskirts
The amount of Roman coins earned is determined by the player's battle level and the battle level of the NPC. Additionally, a player can increase the number of Roman Coins earned through Land Battle activities by joining a Union with that benefit.

Roman Coins are used as "currency" to purchase:
1. Chests at the Coliseum
2. Items at the various Guild Shops found at GMs.
3. To build custom Techs
