|1.17|| The experience bonus for having a single Hero and owning a tier-2 or tier-3 town hall has been increased to +15%/+30% from +10%/+20%.|
|1.13|| Militia can now only be created from a player's starting Town Hall, but they can still be created from any of the player's Keeps or Castles.|
|1.10|| Gryphon Aviaries now require a Keep instead of a Castle. However, both the Cloud upgrade and Gryphon Riders require a Castle to access.|
At tiers 2 and 3, a player who owns only one Hero (dead Heroes count) will gain bonus experience. This bonus is 10% at tier 2, and 20% at tier 3. This affects all experience gain--both from killing creeps and enemy units.
