Hate
Any unit attacking a unit it hates will do an extra 50% damage. Note that if a unit hates another unit it also hates the other unit's upgraded version, but hating the upgraded version doesn't automatically mean hating the non-upgraded.
Hatred is a symmetric relation: if unit A hates unit B, then unit B hates unit A.
The following units hate each other:
- Angels and Archangels hate Devils and Arch Devils
- Genies and Master Genies hate Efreeti and Efreet Sultans
- Titans hate Black Dragons
