- Because the base power of Beat Up is determined by your other party members, there is no specific base power. I will give an example however.
The formula for calculating the base power if Beat Up is as follows:
Base power = (party member's base Attack) / 10 + 5
So let's say all of your party memebers are healthy, and all have a base 100 Attack stat.
100/10 + 5 = 15
15 x 6 = 90
Expect this number to be much lower though.
With STAB: 90 x 1.5 = 135
2.If we use the example from earlier, then with the Choice Band the base power would become 135, or 202 with STAB.
90 x 1.5 = 135
With STAB: 135 x 1.5 = 202.5
3.Sneasel is already quite fast, and if you're going to give it a Choice Band moves like Night Slash would be better than Beat Up for use. I would recommend an item like a King's Rock or Scope Lens, but King's Rock is probably the most viable, because again Night Slash works better with a Scope Lens.
