Chaos weapon upgrade

I just upgraded the Exc Chaos lighting Staff to +11 . wizadry 119 + option rare 20% , but it is weaker than a Platina Staff +12 with 121 wizardry and 10% epic wizardry. Am I misunderstanding something here? The "rare" line isn't a separate option; it’s already factored into the staff's stats.

@DarkWizard

You're reading it right: the rank line isn't a separate bonus, it's already part of the staff's wizardry rise. Your Rare rank gives +20%, so your +11 staff shows 119% instead of 99%.

The reason the Platina feels stronger is the comparison itself. Your Chaos is +11 and the Platina is +12, and one upgrade level is worth about 5% rise. On top of that, the Platina has an excellent option "Increase Wizardry Dmg +10%". That's a separate excellent option, and it can also drop on a Chaos staff.

Compare them at the same level and the picture changes. At +15 Excellent:
- Platina Staff: 139%
- Chaos Lighting Staff, Rare: 142%
- Chaos Lighting Staff, Legendary: 154%
- Chaos Lighting Staff, Epic: 167%, the highest wizardry rise of any staff in the game, above the Divine Staff of Archangel (162%)

So keep upgrading it: at the same level a Rare Chaos already beats the Platina, and each rank above that pulls further ahead.
