gold pieces
general
You can get gold pieces for…
- winning: 20 gp per defeated level.
- losing: 8 gp per opponent's level.
- selling items in shop.
- selling gladiators in shop.
Strategy
As the increase in value of a glad is per fight and not per level, it does not relly make sense to farm gp by treaining and selling glads. Unless you can swap one lvl 70 with another and make profit (very experienced glad).
