Ability Target Data

• Created an Asynchronous method (latent action) that can send a target data to server.
• The ability sends the target data to server, and upon receiving, the appropriate ability action is performed.
• So a player can blink to a target location that was set by local input values, and action will be performed by Server.

Passive Ability & Break

• Triggering a passive ability based on an event.
• Break effect prevents the passive ability from activating.
• Implemented Mana Burn from dota - notice how mana is damaged on melee hit, and when passive is disabled (break effect) mana burn does not happen.

Curve Tables, Magnitude Modifier Calculation Class & Effect Execution Class

• Used Magnitude Modifer Calculation Class for complex calculation of an effect modifier.
