[Meta thread] Iron's PokeRole Adventure: The Skull Ruins

[Dragonstrike]

And that Pokémon battle show something: Iron Head is a little OP move in the Pokerole.

(Note: the following assumes all the dice used are fair, balanced dice that are not biased in any way)

Try Serene Grace boosted dedicated Flinching moves.  That's a barrel of fun.  3 dice is normally about a 42% chance of the effect procing.  5 dice give about a 60% chance: the same odds of getting a Serene Grace boosted Flinch in the main series games.

Or if you want some REAL fun, let's do Serene Grace Tri-Attack (which both the Togepi and Chansey lines can do because of XD and Gen 1 respectively).  Serene Grace adds +2 dice to the chance dice pools of all effects, not just doubles the overall odds of the effect procing.  Which means your 2 dice for each of the 3 statuses goes up to 4 dice per status.  Let's look at the odds of that.

With 2 dice, the odds of an effect procing is about 30%.
With 4, the odds become about 51%.
So each individual status has a fairly good chance of procing separate from each other.  But together...

So, with 6 chance dice, the odds of at least 1 of the 3 statuses procing is 67%
And with 12 total, that shoots up to about 89%.  Per use of the move. 

Of course, the odds of specific combinations of the statuses procing in a single use are lower. Still pretty crazy though.

But yeah.  Serene Grace boosted Tri Attack is busted.

This is also why Aspis holding the Necklace of Serenity is so scary, because the Elemental Fangs follow a similar pattern.  The odds of procing any effect with each of the fangs is:
-51% without Serene Grace (4 dice)
-77% with Serene Grace (8 dice)

And that's particularly fun with Ice Fang because that means it has a 77% chance to make your target lose their next action (though one of the causes makes them lose their whole turn...and the next few as well if they aren't thawed quickly), which is ridiculous.  That's worse than Serene Grace boosted Air Slash/Headbutt/Iron Head.

Oh, and then there's Smog/Poison Fang/Crush Claw/Fiery Dance/Rock Smash/Octazooka/Razor Shell (its chance of lowering defense got gimped HARD in base pokerole, though. Only 1 die for its defense lowering when it has a 50% chance to proc the effect in the games? Really?) /Leaf Tornado/Charge Beam (I find it interesting that they didn't give it more than 5 chance dice, tbh, since it's the only move with a 70% chance of its effect triggering in the games)/Night Daze/ Seed Flare/Sacred Fire/Luster Purge/Mist Ball/Diamond Storm (the last two aren't listed in the book since they're Plot Device moves, but I imagine they would also have 4-5 chance dice for their effects since 40-50% chance effects are rather significant.)

With 7 dice in the pool, that's a...72% chance of the move's effect procing.
Oh, and 1 chance die is about a 17% chance of the effect procing, just so you know.

Fun Fact: I spotted a typo on Bulbapedia as well that said Powder Snow has a 50% chance of freezing the target(s) while staring at the Serene Grace wiki page.  Someone oughta fix that...
