Concurrent Events Setup


What's the setup in order to enable multiple events that share variables in common?

Let's say I have 2 variables of type float : Exp Multiplier and Mastery Multiplier, in the settings config.
Is it possible to have a rule that add to them and not override?


Can you elaborate, add to them and not override? And what do you mean by Events? Perhaps the REST API is what you are looking for, so you can set the values via code
