Mage pet weapon...
 

If I'm a 40 mage... is there any reason to give my pets my summoned weapons except for the summon nuke or resists from the dagger? As it is right now (not needing the resists) I don't bother summoning my pet anything which seems rather sad...

I'm fairly certain you have to give your pets weapons so they dual wield, They don't dual wield by default until lv44+

Wow that's shocking but might explain why my 39 Mac pet seems so much better than the others. When i make a new pet i hit trash to find out the level and reclaim cast etc. Fights take so long with min pets comparatively.

Yes give your pets daggers until you get to 44+. Some fire pets might still need them later than others.
