>>18195091A few things:
You multiplied the multipliers incorrectly. 2*1.5*1.5*1.5*2=13.5
Flower Gift doesn't stack.
I'm pretty sure Helping Hand stacks additively - so having it used twice would give you 2x damage, not 1.5*1.5.
+6 252+ Atk Huge Power Shuckle Ice Ball vs. -6 0 HP / 0- Def Noibat on a critical hit: 30301936-35649340 (252516133.3 - 297077833.3%) -- guaranteed OHKO
This is the damage before Helping Hand, Metronome or any other multipliers have been added. We'd get 1.5x from Flower Gift, 2x from double Helping Hands, 2x from metronome, and 2x from forest's curse, for a total multiplier of 12.
After these adjustments, the damage would come to 363,623,232 - 427,792,080, which, is very close to the value or Shuckle's Bulbapedia page. The 48 damage difference is probably down to the way the game rounds things.
It's a lot higher than my Mewtwo figure from earlier though.
>>18195200Nope, the target would need to survive the hit, with a Focus Sash or Sturdy or something. If it did, it'd only deal the same amount of damage that it took, at most, its max HP -1.
