[Meta thread] Lord Windos' PokeRole Adventure : Celadon City Vandels

[Dragonstrike]

Leaf Blade in Gallade (Gardevoir instead if Gallade is already fainted)

Accuracy: DEX (*4) + Fight (2) + Brawl (1) - 2 Actions = 5D6
Damage: STR (*5) + (?) Power (A bit confused about this one) + 1 STAB = ?D6
5D6 vs Gallade
?D6 vs Gardevoir (If Gallade is fainted)
Effect: Hight Crit Chance

So, Accuracy looks good.  Second action will have a -3 Actions accuracy penalty to it since you're using 2 actions this round.

Damage is Strength (essentially attack from the games) plus the move's power (essentially the move's base power in the games.  you can find all the information you need on moves and stuff in the core book) plus STAB - foe's defense.  Add your strength, the move's power, 1 from the Mega Boost, 1 from STAB, and that's your base dice pool for damage.  I'm not entirely sure what our opponents' defense scores are, unfortunately, but Windos can handle that.

So, you have 3 Strength, right?  So that means your damage pool before anything else is factored in is 4* Strength + 3 Power + 1 STAB = 8 D6 base.

Also, the pain penalization thing doesn't kick in until you've lost 2 HP.  -2 HP is -1 Pain, Half HP is -2 Pain, 1 HP is -3 Pain.  Though for you those would be Strength buffs instead.

It's mostly right, just needs a little work before it's entirely correct.
