Apply increased periodic damage using Gameplay Effect in Gameplay Ability System

Let’s suppose I have a Molotov fire effect - where I need to do increased damage every periodic tick.

It follows this formula: 30 + 8 * n,
where n is the number of ticks / periodic applications.

So in the Molotov effect, the damage every period will be ( 30 + 38 + (30 + 16) + (30 + 24) + (30 + 32) ) for period of 4 seconds (period executes on effect applied).

How to achieve this?

PS: I don’t want to use a Curve Table, rather, I wish to do an effect calculation - either Effect Execution Calculation or Magnitude Modify Calculation classes.
