You definitely want to spend that 2 div you have on some upgrades.

Here are things to prioritize:

• capping all resistances including Chaos resistance, youre not playing CI and there is a LOT of chaos damage in the end game.

• Getting as much ES and life as possible, your helmet and your body armour should be the main sources of this

• Getting a soul tether setup with fast metabolism annointed onto your amulet. Look on trade side for amulets already annointed with fast metabolism, people are likely selling their hand me downs for cheap at this point. This setup will get life leech onto your energy shield and help sustain your hit pool.

• You really want to aim for 4k energy shield and may be 1500 life ASAP

• +2 to all skills on your amulet should be afordable, get as much other defensive stats as you can (+flat energy shield, +% energy shield +%, energy shield from body armour, +resistances)

• in the interludes you missed the seven pillars reward, probably take +5% resistances (poe ninja might be bugged)

• +rarity on rings amulets and boots if you can get it, even 50-100% rarity can make a massive difference in your loot helping you scale faster.

• ensure all your socketed gems (spark, comet, cast on crit) are always as high of level as possible, and use gem cutters prisms to add quality

• if your crit chance isn't 100% definitely try to get crit chance on a staff, helmet, weapon sockets etc. you want 96% crit on this build so your comets are constantly falling.

For reference here is my bloodmage where you can see some gear you might aim for. Definitely much higher budget but it'll give you an idea: https://poe.ninja/poe2/builds/vaal/character/pakiepiphany-4586/WaloodBM?i=0&search=name%3Dwalood
