I feel like my damage isn't where it should be. Looking for suggestions.

Trying to do toxic rain/ HoA, damage feels really lack luster. Am I missing something simple, or is this not really a viable build?

70% Spell/Attack Dodge
83% Evade
Don't seem to notice issues from ele aliments.

I can clear T12-T13 maps pretty well. Delve to around 125. Haven't tried to boss, fairly certain I don't have the DPS for it.

I tried changing to +3 bow and more att speed, but that made everything worse.

Suggestions greatly appreciated.

I see a lot of weak stuff in this build, for example the flasks are very vanilla, support gems are sub-par (life gain on hit on ballista doesn't leech to you only to the totem... stone golem with ice bite and ele prolif, I don't think that works either), passive tree picks tons of random stuff but skips poison nodes like fatal toxins and swift venoms...

Tbh the biggest issue is lack of focus of this build.

If you want a bow build with focus on poison, you should be probably playing pathfinder with darkscorn bow, like this guide: https://www.pathofexile.com/forum/view-thread/2551841

If you want to play a herald of agony build, you should probably pick a skill that is best for stacking virulence (like cyclone or ball lightning) and focus on getting highly buffed herald (6-link with proper supports). Kinda like this guy: https://poe.ninja/challenge/builds/char/Zeiin/Zeinsly (apparently lancing steel works too)

If you want a classic toxic rain build, you need completely different supports on toxic rain and different auras, not just a +3 bow. Follow this guide: https://www.pathofexile.com/forum/view-thread/2866127 Or check Zizaran's video specifically for Raider. https://www.youtube.com/watch?v=aJ4taUgnwNg
