Right now some heroes have special ability while others don't such as bellepheron jump attack.
The polymphemis bash but other heroes like Ajax, Odysseus Pharoah, Hersir atlantean heroes don't have special ability.
For hersir u can have special ability where attack increases by number of heroes similar to wolves.
For Greek heroes have a unique ability it could be nice to have some special ability similar to Arkansas where heroes makes all infantry unit increase attack as a morale boost.
This request is to have a consistently across all heroes units and their special ability can be whatever so long as they have one like the myth units cooldown effect.
