Diablo – What gives 5% critical hit chance and 50% critical damage

Only when you connect with a real-life player will the monsters get harder.

The in-game NPCs that you can recruit make no difference to the difficulty and you will continue to receIve the same experience and loot.

On another note, the loot differs from player to player, so you dont have to worry about people stealing it.

Each hit does 111% weapon damage, and you hit 7 times.

I'm not positive, but I think each hit is randomly decided among available targets, so although unlikely, you can hit the same target 7 times even if other targets are available. If only 1 target is available, you will hit that target 7 times.

I haven't tested much with the range, so I don't think I can answer that part of your question very well, but if you use the ability on a regular basis you should get a good idea of the sort of range it will hit since there is an animation that shows you who you are hitting.

You do not have to be next to the target to hit them though, and I'm not even sure you need to be targetting anyone to use it. For example, one of the runes you unlock for the skill will teleport you to your target when you use that ability, so I have used it to target an enemy across the screen and teleport there.
