Bone Horror question

When I died in the catacombs in pre-searing ascalon (Because of the fire trap) My bone horror started to attack my fire imp. So I ran back there and i saw my imp standing there (I didn't saw my bone horror). So my question is why did my bone horror became an enemy? Also is Necromancer Munne supposed to join your party when she comes with you (The necromancer's novice Quest)?

It's one of those things that happens in GW - your minions are "bonded" to you. When you die, the minions become "un-bonded" and will attack dam near anything - friend or foe. (The Imp probably killed the minion)

As far as Munne is concerned - I dunno about joining the party, but she is supposed to go with you.

When the master of a bone minion dies or loses it's master due to certain skills, the minion is masterless and attacks anything nearby.

Thanks for the answers . And about Munne, it's possible to summon a fire imp while she's in the party, right?

I use this for giggles. I would sac myself and let my minions run amok. Sometimes the minions will kill a party member. I would strongly suggest not doing this in a middle of a quest or a mission.

Yes, you can summon the im in every situation, unless you are level 20 or there already is one in your party.

or when he died and your still "suffering" from summoning sickness.

Non-player characters accompany your party as allies only when part of your task is to keep them alive during the quest or mission. Otherwise they simply accompany you if the quest or mission calls for it and you don't need to worry about what happens to them. For example, Farrah Cappo will be listed in your party window as an ally if you are a primary or secondary monk doing the pre quest "Protection Prayers", since your job is to keep her alive as she fights bandits and the quest fails if she dies.

There is no limit on the number of NPC allies you can have with your party, except that only one summoned ally can be among their number. Allies do not count towards the limits on the number of party members. Later you will find quests where many allies are listed in your party window, and you usually have to keep at least some of them alive.
