Synergy used event
 

Hey,
Is there any way to figure out when somone uses synergy? Any event or something?

Have you checked out this event? EVENT_SYNERGY_ABILITY_CHANGED (number eventCode)

Also check out sidtools. It will output all the events that take place. Then activate or have someone activate a synergy and see.

As far as I remember, EVENT_SYNERGY_ABILITY_CHANGED always fires when several synergies are usable and the active to use one changes. An event that fires ON_SYNERGY_USED does not exist, if I remember correctly, I would have use for it myself.
