Orc Arena

You can allocate forces and heal wounded units here. Wounded Unit Rate: 75% of units defeated in battles against monsters and 60-80% defeated in battles against Players return as wounded units. For every level increase in the Arena, wounded unit recovery time decreases by 1%

The Arena serves several functions in Heroes of Gaia:

• It allows allocation of units between heroes.
• It provides a method of healing fixed % of troops lost in combat. The recovery rate of wounded units increases at a rate of 3% per Arena level, up to a maximum of 30%. Prior to Tower of Babel Expansion, this was 1%
• It allows disbanding of units currently assigned to a hero.
• It provides access to the Arena, which allows for regulated PvP combat. Units are wounded at a higher rate during Arena battles, however the percentage reported in-game is suspect.
