Definitely, spirits are especially good, and with the new expansion, they even steal arrows...

They only steal arrows if the archer is within their movement range! And what will you do, attack the archer or steal mana? I think you should attack! But that's not important! Usually, the player has a cart with ammunition! So, this ability is useless! Ghosts are better! They steal mana when they attack and use it to restore their health! But still, the bonus from the Master Archer skill wins 8 times out of 10! The ghosts won 2 times, and even then, there was only 1 and 2 of them left (tested without magic and any skills at the first level)!:smile01:
