Right the weapon upgrade:

As you said in the OP I assume you know the following:

Basically use all the animal stuff to increse the multiplier, then use the big XP giving mechanical items in order to give the weapon loads of XP.

After you upgrade levels of a weapon you will eventually reach a "star Level", after this you need a special item to upgrade it to a "tier 2" weapon. The final Tier weapon is a Tier 3 weapon.

I stuck with Lightnings Gladius weapon

BUT really you want the weapon that suits the way your playing, I was using lightning as a commando more so Gladius was a good matched as its original affinity towards Strength was higher than magic.

Light's origninal weapon blaze Edge is more balanced apparently.

Then you get a weapon for Hope that adds a EXTRA +500 MAGIC when you level it up to a tier 2 weapon. No idea what the weapon is called though, sorry.

Right now I'd reccommend that you upgrade lightnings weapon & keep gladius on her if you wanna focus on light as a commando, even though I use her more as a ravager now.
