Flail

Type Power Accuracy PP Priority Damage Target
Normal 1 100% 15 0 Physical Single non-user

Description

Deals damage. Flail's Base Power increases as the user's HP decreases, with a range of 20 to 200 Base Power. Base Power is calculated thus:

X = (user's current HP * 48 / user's maximum HP)
Value of X Base Damage
0-1 200
2-4 150
5-9100
10-16 80
17-32 40
33-48 20

Alternately, you could do it as a direct function of your % HP, although this value could be off on borderline cases due to rounding.

% HP remaining Base Damage
0% - 3.124% 200
3.125% - 9.374% 150
9.375% - 20.3124%100
20.3125% - 34.374% 80
34.375% - 67.1874% 40
67.1875% - 100% 20

Competitive Uses

Using Endure or the ability Sturdy ensures that the user survives at 1 HP, maximizing Flail's Base Power. Flail is stronger than Return or Frustration while the user is at 4% HP or lower.
