Should be unsummonable.

It's like the talk on edges, if everyone picks the same one, something's wrong.

When that area was written I doubt someone thought that this mob would be the default, the always chosen first mob, to summon to stop invokers, bards, berserkers, anyone who does area effect or autoattack.

There are hundreds of very strong, healthy mobs that are second choices now, like dwarves, giants, etc. The bandit chief should just be made unsummonable. It's a one-shop-stop game changing mob that does a player's job. It is both a warrior with reliable cut off and reliable legsweep and reliable slice, as well as a thief with reliable cheap shot. It's better than a player, really, as it will never flee even if it is going to die, so it sacrifices itself for the summoner ganger.

You want meat shields? Summon other mobs. This one should be removed from the list.
