# (Solved) Overlapping element rate modifiers

Hey all!

Quick question: In MV, suppose I have 2 elements, let's call them X and Y for simplicity, an actor and two equipment pieces, both of which can be worn at the same time by my actor.

My actor has the element rate tags X * 120 and Y * 80 by default.
I equip the first equipment piece, which has the tags X * 50 and Y * 200.
Then I equip the second piece, which has Y * 40 only.

How much damage would my actor take from either element, with all other factors being neutral?
Also, if it isn't 70% from X and 120% from Y, how can I make it so it is? (I get that this is probably a "you'd need a plugin" style thing, so if there's one out that can do this then please let me know!)

Sorry this sounds so much like a maths exam question Thanks for reading, and good luck in your own projects!

I believe that all element rates of the same element will stack multiplicatively, so:
• The actor will take 120% * 50% = 60% damage from Element X.
• The actor will take 80% * 200% * 40% = 64% damage from Element Y.
I'm not aware of any existing plugin that changes the stacking to additive (which sounds like what you were expecting), but yes, it could certainly be done.

It's mulitplication, so multiply the element rates. X will be 1.2 * .5 which is .6 or 60%. Y is .8 * 2 *.4 which is .64 or 64%.

I'd honestly just redo the * so it works out to the numbers you want, as the system was always meant to be * for element rates. Changing it to + will break more things than it will fix.

Well, if it stacks multiplicatively, and there's no easy way to change that, then I guess it's back to the drawing board. Oh well, I know more now than I did before, and that's never a bad thing! Thanks!
