I'm working on upgrading my Skeleton Mage setup now that I have a real budget for upgrades. I have about 25 Ex in the bank and another 10-12 Ex worth of stuff I'm trying to sell for further upgrades.

I started off following a leveling guide and now I'm trying to adjust to follow the more popular builds I see on POE Ninja but I know I should make some adjustments

Current POB: https://pastebin.com/XzryHiTe

Possible upgrades: Swap the belt for Darkness Enthroned and a couple of 20% minion damage if used recently jewels. But, that makes balancing resists harder.

I'm running a pretty cheap Animate Guardian setup, I could invest in a more expensive setup with Garb of the Ephemeral and Kingmaker.

Finding a better source of DEX to drop the point in Expertise (and the placeholder Anoint on the gloves to fix my DEX issue)

Fix Anoints, maybe by pathing over to Death Attunement? But what do I give up for that?

It looks like most builds on POE Ninja are running Generosity with Zealotry, I have room for that but are Determination, Defiance Banner, and Tempest Shield still the correct other auras to pair with it? I see some people adding on Aspect of the Spider, is that worth all the reservation-juggling it would take?

I know I could upgrade rings, maybe find a better skeleton-damage-enchanted helm, and perhaps find a shield that also has reduced reservation or some other useful stats. But I don't know what to prioritize.

Any advice on changes, or ideal upgrades and what order to put them in would be welcome. Thanks!
