Has anyone ever build a pure dodge character? Something that just doesn't get hit like 99% of the time? I remember doing that when I played Ragnarok Online, and I feel like PoE offers that more than any other ARPG given the mechanics.
Yeah I have built that type of character before. Ranger is my favorite class and Raider is my favorite in it so my characters are usually very evasive heavy. Just remember that evasion and dodge are two different things (evasion is a matter of your evasion rating versus their accuracy so it's not just what you see is what you get but dodge is complete dodge and is more powerful). This is two layer defense where it checks for one and if it goes through it checks for the other.
Evasion and dodge is capped though (dodge at 75%) so you will never be completely untouchable. The idea is to use the following uniques alongside the Raider ascendancy (frenzy path and phasing path):
2x Dreamfeathers (these weapons scale off of your evasion)
Atziri Step (15% spell dodge which is very hard to get by, plus ton of flat evasion)
Hyrri's Ire (10% attack and spell dodge, plus ton of flat evasion )
And then you get Phase Acrobatics keystone in the skill tree which gives you like 40%+ attack dodge (combined with the Raider ascendancy nodes) and 30% spell dodge. You can also take the Kaitlyn quest for some more dodge and some of the Pantheon and enchantments also give spell dodge just don't go over 75% as its a waste. It's not even needed to take the Kaitlyn quest, just at the start then respec out.
For your flasks:
Stibnite: Creates a smoke that blinds plus 100% evasion. Blind is an extra layer of evasion and is excellent against bosses.
Jade: Flat evasion
Quartz: 10% dodge on spell and attack which is the final piece of the puzzle in order to get 75% spell and attack dodge capped.
Aura: Grace which gives a ton of flat evasion. And this evasion also feeds your Dreamfeather.
The rest is just getting evasion where you can on your hear like gloves, helm and jewelry but you need to have life and resistances on all these items. You can also use Starkonja unique helm if you want.
You will end up with like 60k-70k evasion rating (or more) and 75/75 attack/spell dodge when you have all of your flasks up. Trash mobs will never hit you and even bosses will have trouble hitting you though if something does go through it will hurt.
This build also makes you freeze/chill, burning and shock immune. Once you get curse, poison and bleed immunity on your utility flasks then no ailments while touch you either.
