This is basically a gaming question :)
On an action, an ability can be triggered 50% of the time. This can be upgraded one of two ways.
This first is simple, it can be upgraded to 65%
The other is less simple, it can be upgraded so that 35% of the time, the action will trigger again, with both actions having a 50% chance that the ability could trigger.
So Action -> 50% Ability trigger. Then 35% chance that the action triggers again, again with a 50% chance that the ability triggers again.
Triggers always have a 15% chance they fail.
If I care about the ability triggers, which is better?
