Basic Combat System guide
Boost Attacks
When you and your foe are both moving at top speed and you execute a Rush Attack before your foe, it becomes a Boost Attack.
Boost Attacks let you stagger and deal DMG to your foe, while also shortening your skill cooldowns.
Immune to All is also applied to you during Boost Attacks.
Boost Attack Counterbalance
When you and your enemy execute a Boost Attack at the same time, the attacks are counterbalanced and cancel out
Immune to All will be applied to both of you during this time.
Having an attack counterbalanced still lets both sides earn EXP.
Finishers
If you use a Rush Attack to finish off an enemy hero, it becomes a Finisher. Executing a Finisher applies Movement Speed Up to you.
If you execute a Finisher with an ally, it turns into a Team Finisher.
Doing this instantly puts you into high-speed movement and applies Movement Speed Up to you.
Immune to All is also applied to you during the Finisher.
