A death count timer is one that just uses the deaths triggers to make non-stacking waits. With hypertriggers, you can add/subtract 12 deaths per second approximately. For that trigger, I made it add 36 deaths. That would equal 3 seconds. In the condtitions is has "Current Player has suffered exactly 0 deaths of (the unit)". This will make it so that when the timer is on, the trigger won't run, just like a timer. Then I have the trigger subtracting the death counts at 12 per second. Hope that clears things up for you.
