Patch 0.4 has a weird little rabbit hole in Path of Exile 2: if you push Reduced Skill Effect Duration all the way to 100%, the game starts feeling like it's missing a rule. Stuff that's meant to "wait" just doesn't. If you're gearing up to try it, you'll quickly notice how picky the setup is, so having the right PoE 2 Items ready beforehand saves a lot of stop-start farming and respec pain.

Why Titan is the cleanest route

People will tell you "any class can do it if you try hard enough," but in practice Titan Warrior is the smooth path. The key is Hulking Form, because it juices the value of small passives by 50%. That one line changes everything. Without it, you end up stuck at an awkward number like 92% or 96% and you're forced into clunky compromises. You'll also want to be roughly in the level 70 range so you've actually got the points to stretch across the map without gutting your core defenses.

Passive tree priorities that actually add up

Start by working toward Near at Hand, because it's a chunky chunk of reduction and the travel nodes leading into it become way better once Hulking Form is active. Next, swing through the Boundless Growth area and scoop the small reduction passives there; they look minor, but with the Titan scaling they stop being "filler" and start being the difference between "almost" and "done." After that, you're usually pathing toward the Witch side to grab the Forthcoming cluster, since it stacks nicely and doesn't force a bunch of dead nodes. One more tip people miss: don't waste points walking to Searing Heart—just anoint it on your amulet and keep your tree tighter.

What breaks when duration hits zero

This is where it gets silly. Ember Fusillade is the headline example because its normal behavior includes that little floaty delay before firing, and at 100% reduction the delay basically vanishes. Pair that with Dusk Vigil and you can end up with nonstop, instant projectile spam that feels like you're holding down a trigger. On the defensive side, Time of Need goes from "nice periodic sustain" to something that seems to tick constantly—cleanse, heal, repeat—so chip damage and most degens stop mattering unless you get outright deleted in one hit. If you're testing these setups, it's smart to keep your upgrades and currency flow steady; that's where U4GM comes in handy, since it's a straightforward place players use to pick up game currency and items without derailing the whole experiment.
