I have about 1200 hours in game. I tend to play in bursts, and when I started my most recent one I didn't have the patience for a league start so I decided to see how far I could get my EHOTS Deadeye in Standard. I've put probably 150d into this character (some stuff not shown, since I upgraded past it and just haven't sold it yet) and I don't have a problem making a few dozen div a day, so that informs my budget.
I play on Steam Deck and on my gaming PC, so I use the controller layout for both. This limits some of the content I can access--I have doubts I'll ever handle the Simon Says part of the Maven fight with this setup--but I'd like to experience as much content as I can. I'm not particularly great at the game: I think I burned through 6 omens getting from 95 to 96.
I have two voidstones (Eldritch and Originator), and I'm still learning the bullet hell part of the Shaper fight. I've beaten Catarina and Atzoat'l Aztiri and some breach big bad who showed up kinda randomly. I've beaten all of the synth minibosses, but I haven't fought Cortex yet. I have the lowest tier Maven invitational on farm status, but haven't yet tried any of the higher up ones.
Here's my build: https://poe.ninja/poe1/pob/8fea2
I'm doing a poor man's Mageblood with cast-on-full enchants on my rightmost 4 flasks. PoB says I'm at 97% spell suppression, but in game it shows 100%. I'm sure there's some stuff I'm doing suboptimally, but when I go to change too much I get stuck in having to redo the entire build because I either can't find or can't afford the gear that would be a drop-in improvement for what I have.
I'm currently swapping between Barrage Support and Mirage Archer on EHOTS, depending on whether I'm clearing or need a Death Laser for a boss. The Death Laser mode melts pretty much any standard boss relatively quickly, but I'm very dependent on keeping my crit rate up to stay alive, since my ailment immunity, armor, and crit rate all depend on flask uptime.
So, where do I take this build from here?
