Unreal Engine character animation

Currently im using ALS v4 system, needs additional melee attack animations for this. All animations for a third-person character: 2-3 for a one-handed weapon (combo animations - each can continue the previous one) and the same 2-3 for a two-handed one. There are many animations on the marketplace for swords and the like, but they are only good for arpg games. It is desirable that the animations are only for the upper body and the character can walk at the same time as attacks, but I'm not sure if this will look good. This needs to be discussed in more detail.
