Necro pets
 

The necro spectre pet seems to not be dual wielding & double attacking (quad per round).

Fairly sure a spectre pet would be able to solo the entrance mobs at sebillis back in the day, but it is certaintly not the case here - it seems to be due to the lacking dps.

I haven't checked google for proof of it, would probably be tough to find parses from that time - but doesn't anyone else remember the pets being really strong?

It could definitely NOT solo seb mobs.

Necro pets (not sure about Mage) are not dual wielding unless you give them weapons. It's totally a bug and reduces their damage significantly unless you carry around a bag full of weapons.

There's a timeline/patch for this and pets that should and should not do this automatically.
