Trapping moves, like Fire Spin, Whirlpool, and Clamp now do 1/8 damage each turn instead of 1/16. Binding Band originally increased the damage from 1/16 to 1/8. Now, will it increase to 1/4? Because that is a little high...
>Whirlpool+Sub+Protect Starmie=66.67%-83.3% damage guaranteed if it still lasts 4-5 turns, Binding Band does 1/6 per turn and Starmie outspeeds.
So, it goes from 1/8 to 1/6. Hooray!
Hope I helped. :)
