How does the damage counting works?

So recently I´ve been wondering how the game counts your damage.
Say you find Small Rock, Steven, Magic Mushroom and Synth Oil in that order.

Does the game count it in that order, say your base damage is 2 (I do not know the actual numbers) so would it go
2 + 1 + 1 + 0,3 x 1.5 + 1
or does the game count the "pure damage" together first and then the multipliers, so like following
2 + 1 + 1 + 0,3 + 1 x 1.5

So does anyone know?

Multipliers are counted last. And you can only have one at a time (not counting special items like Polyphemus or Sacred Heart which have a specific formula).

Also, your base damage is 3.5 (with Isaac), and any DMG Up you get isn't a simple addition (I mean, if you take an item like the Pentagram, which is a +1 DMG Up, you WON'T get exactly +1 DMG, but a little less or a little more depending of you actual DMG. The more DMG you have, the less efficient DMG Up are.)

The Curved Horn trinket is an exception, giving exactly +2 flat DMG, thus being very efficient if you already have very high DMG.

I´ve heard that Lazarus´ Rags after respawning gives 1.2x multiplier and if I were to get Magic Mushroom then which one would it count? First or last? Or the larger multiplier?

Thanks for that info

That´s kind of odd.

That I knew, that it´s added on top of your damage, outside the formula.
