Maximum Mods Possible?

15^50 does not drop on purple items. I would put money that the one you saw was 15 below 50, they certainly look the same at quick glance.

The energy types of mods for staves (+5e^50) and armor mods for shields (+5ar vs xxx) can drop on purples.

Otherwise the rest will be one or more off from max.

Shields and focuses can have the maximum +5 for conditional armor, as well as max physical damage reduction(-2 stance/ench, -3 hexed), and the max 20% condition reduction you mentioned. That’s it for inherent mods. Makes for some sexy perfect purples, most people aren’t impressed by them, those people are wrong🤪.

My 'holy grail' shield would be to find a q0 ar8 bladed* shield with -2^e / +33hp^e

It's what I pray for from shing jea chests or bird droppings when I farm feathers once in a while. I know it 'could' exist, I just fear it dropped and the person never paid attention.

*(or maybe kappa, gotta try that chest run in NM to test drops)
