Test 9: 94-64=30?????
Did I make a mistake in calculating the damage? I used Cardsofthehearts excel sheet to help calculate the damage. I really hope this means i just messed up somewhere (FYI a +1 Defense boost for skarmory would not have reduced the damage to only 30, but about 27), I checked my pokemons stats and they are the same ones i reported earlier.
You did not make a mistake. Rather, me and Peterko have.
It seems like Tinted Lens' multiplier is in Mod3 and not Mod2!
I realised this after noticing that all numbers are even.
So the test means that we put Tinted Lens in Mod2 by mistake, where it should be in Mod3. Hence we have:
Bolded x1.5 = Boost for Me First, Bolded x2 = Boost for Tinted Lens
If R = 0.85, 0.86 or 0.87: 17
x 1.5 = 25, 25 x R = 21, 21 x 1.5 = 31, 31 / 2 = 15, 15
x 2 = 30
If R = 0.88, 0.89, 0.90 or 0.91: 17
x 1.5 = 25, 25 x R = 22, 22 x 1.5 = 33, 33 / 2 = 16, 16
x 2 = 32
If R = 0.92, 0.93, 0.94 or 0.95: 17
x 1.5 = 25, 25 x R = 23, 23 x 1.5 = 34, 34 / 2 = 17, 17
x 2 = 34
If R = 0.96, 0.97, 0.98, 0.99: 17
x 1.5 = 25, 25 x R = 24, 24 x 1.5 = 36, 36 / 2 = 18, 18
x 2 = 36
If R = 1: 17
x 1.5 = 25, 25 x R = 25, 25 x 1.5 = 37, 37 / 2 = 18, 18
x 2 = 36
So the damage should be either 30, 32, 34 or 36... exactly as you had in your test.
Now what can clash in Mod3 is having a Pokemon with Tinted Lens using a Normal move against a Steel or Rock Pokemon holding Chilan Berry.
This would first warrant another question: Does Chilan Berry work if the Normal move used against the Pokemon holding it is not very effective? For example, suppose I use Hyper Beam against Steelix with Chilan Berry attached... would Chilan Berry activate or not? If it doesn't, then Tinted Lens does not clash with Chilan Berry.
If, however, it activates, then Tinted Lens clashes with it, and we would need to know whether Chilan Berry (x0.5) activates first followed by Tinted Lens (x2), or the other way round. A test would be simple for this, though. If the damage done is always an even number, then Tinted Lens activates last, otherwise Chilan Berry activates last.
Thanks RB Golbat for this test!
