Need help with skills (Diablo 2)

Hello everyone. Question about the multi-shot amki and the shape of the wolf. If you shoot a multishot and several arrows hit the enemy at the same time, will it be counted as one, or the damage will pass from several?
How does ias work in a wolf? When pumping, it is written that Ias adds, but in fact, when you become a wolf, the attacks are visually slower. What is the reason for this? other breaks? or the speed attacks are still the same and it's all just visually
Good for everyone
