Paint Ball
Has a higher catch rate based on the diversity of move types the enemy Pokemon has
1x for 0 types
1.5x for 1 type
2x for 2 types
2.5x for 3 types
3x for 4 types
(curse doesnt count towards this unless used by a ghost type, so only way to get 1x is to find a pokemon who only knows curse and isn't a ghost type)
