Running Blight Maps in Path of Exile
If you're looking for a Poe Blight Tower Guide, you've probably already spent some time running Blight maps and figuring out which towers actually matter. The basic idea is straightforward: you defend a tower from waves of blighted enemies by placing your own towers around the map, and your goal is to keep them from being destroyed while dealing enough damage to clear the waves. I spent probably 40 hours min-maxing my initial setup before I stopped overthinking it. The thing that nobody tells you upfront is that most towers are completely unnecessary. I used to run every single tower type on every map, and it took me longer than it needed to because I was spreading my resources too thin.
Poe Blight Tower Guide Basics
There are four main tower types in Blight maps: Artillery Tower, Arcane Tower, Fire Tower, and Cold Tower. Each one costs a different amount of blighted currency to upgrade, and each one has a different damage profile. Artillery towers hit hard but have slow attack speed. Arcane towers scale well with spell damage. Fire towers do consistent single-target damage. Cold towers apply chill and slow, which matters more than people realize. When you place a tower, you can orient it by clicking on a direction. This actually matters. I used to just place towers randomly and wonder why my clear rate was inconsistent. Rotating your tower so it faces the path where enemies will spawn instead of just pointing at empty space makes a noticeable difference on later waves. The map itself also matters more than most players account for. Maps with chokepoints like narrow corridors or long straightaways make the fight significantly easier because your towers can hit enemies from a safe distance. Open circular maps with multiple entry points are miserable and usually not worth running unless you're very confident in your build.
Here's something counter-intuitive that took me a while to learn: stacking cold and fire towers on the same map is almost always worse than focusing on one element and going all-in. Your towers don't benefit from combining elements unless you've specifically built your character to trigger elemental junction or similar effects. If you're running a standard Blight clearing build, just pick fire or cold and max out that one tower type. You'll clear faster and spend less currency doing it. Another thing that trips people up is the placement distance mechanic. Towers placed too close together don't actually synergize. Their attack ranges overlap in a way that wastes potential damage output because enemies who would have been in range of one tower are already dead from another. I found that spacing towers roughly two tile widths apart from each other usually gives you the best coverage without wasting damage potential. I hit a wall recently where I was running Level 10 Blight maps and consistently failing on wave 8 no matter what I changed. My towers kept dying before the wave ended because the blight spawn rates were overwhelming my single-target damage. The workaround was to stop trying to clear all the enemies and instead focus on holding position. I pulled back my tower placements by about four tiles compared to my usual setup and let the enemies walk into range rather than leaning forward. It sounds backwards, but it increased my survival rate from maybe 40% to about 75% on those difficult maps.

Upgrading towers costs blighted currency, which you earn by killing blighted enemies. The currency values scale with map tier, so a Level 5 tower upgrade on a Tier 15 map costs significantly less relative to your income than on a Tier 8 map. This means it's actually more efficient to run high-tier maps for Blight clears even if they feel scarier at first. The math works in your favor after about wave 5. One limitation of this system that bears mentioning: Blight towers don't work well with certain build archetypes. If you're running a pure physical damage build without any elemental modifiers, your towers will underperform compared to builds that incorporate at least one element. There's no workaround for this except either changing your build or accepting lower clear speeds. It's not a failure of the tower system itself, just a mismatch between the map mechanics and certain character designs. If you're starting fresh, I'd recommend picking up a simple elemental bow or spellcaster build first. They synergize naturally with the tower mechanics and give you enough feedback to understand what's working. Once you have a feel for the map layouts and enemy patterns, you can experiment with more exotic setups.
The community resource at poeplant.com has decent coverage of this topic and I reference it occasionally when I need to verify specific tower stats. Most of the information out there repeats the same surface-level advice, so don't expect it to explain the kind of positioning adjustments that actually move the needle on harder maps.
