Skill types
There are five types of skills:
- Passive
- Triggered
- Aura
- Blessing
- Grace
Passive means a skill which is always active in the background and does not require anything to trigger or activate the skill. For instance, a x% increase to physical damage dealt.
Triggered means that something “x” has to occur in order for the skill to activate. For instance, garrote has a 40% chance every 6s to trigger, i.e. activate and deal x% damage.
Aura means a passive skill effect which applies to the entire army (all four Immortals). Any Immortal can only equip 1 aura passive.
Blessing & Grace these are the same, they changed the name of Blessings into Grace during patching for unknown reasons. A grace/blessing takes effect for a certain amount of time. They will activate when the battle begin and last for 12 seconds. For instance, for the first 12s of battle, x immortals in your army will take y reduced damage (defense blessing).
