Guide:Blight quick guide
The following guide shows you how to complete a Blighted map encounter. In blighted maps, players have 5 minutes to kill a great deal of monsters that spawn from fixed portals. These portals appear over the course of time and players are granted power to build towers. Each construction or upgradation of a tower costs a certain amount of power. As you kill enemies, you will earn more power. In this guide you will annoint your Blighted maps with

s, that decrease the cost of building and upgrading towers, allowing you to have far more towers.
This guide uses the Scout Tower strategy, which is to place down towers that summon powerful flying minions to attack monsters, greatly reducing the amount of damage the player must do. There are various strategies and methods that can be used to successfully complete a Blight encounter and this is just one of them. This guide does not state that Scout Towers is the recommended strategy, however, it is the easiest method for beginners and learners to get started with Blighted maps.
In this strategy, you will be running around and placing Scout Towers at strategic locations and then staying in the center to kill the mini bosses that the towers cannot finish off.
Recommendations
The following is recommended:
- A ranger or spellcaster build or any build that can do high amounts of area damage (melee builds using Cyclone without Cast-on-Crit will find it extremely hard)
- At least 2 million damage per second (rolling over your main attack ability should show 100K+, because Path of Exile cannot calculate DPS properly)
- A method to increase damage against Rare and Unique mini bosses (such as Assassin's Mark for crit-builds, or Sigil of Power for lightning-builds)
- Capped elemental resistances (fire, cold and lightning resistance at 75%)
- At least 5,000 Effective hit points (Life pool)
- At least 20% block or evade chance, or Mana before Life defenses

Annointing tips are as follows:
|
| 4 | 
|
Now place your annointed Blighted map into your map device and start it.
|
| 5 | 
|
The first thing to do is to run to one of the edges/corners of the map and place your Portal there, so you don't accidentally click on the Portal during an intensive fight and lose the encounter. |
| 6 | 
|
Now scout around a map to get a feel of the map layout. |
| 7 | 
|
Click the Ichor Pump near Cassia to begin the blight encounter.
The Purification Pump is the big egg-like structure in the center, which you must defend at all costs. |
| 8 | 
|
Now the Blight encounter has begun. You have 5 minutes to kill multiple waves of enemies and to defend the Purification Pump at all costs.
|
| 9 | 
|
The first thing to do is build an Empowering Tower near to the Purification Pump.
|
| 10 | 
|
Click Imbuing Tower for the final upgrade to the Empowering Tower which increases your damage while you stand it in.
As you can see the radius of the tower has also greatly increased. |
| 11 | 
|
The first wave of monster portals has appeared.
On the map you can see:
|
| 12 | 
|
Run to the first monster portal, and place down a Summoning Tower Mk 1. |
| 13 | 
|
Click the gear icon multiple times to upgrade it. |
| 14 | 
|
For the final upgrade on the Summoning Tower, select Scout Tower (wings icon). |
| 15 | 
|
Next run to one of the junction points where 2 lanes converge, and then place down a Scout Tower over there. |
| 16 | 
|
As the second wave starts you'll see many more Monster Portals appear and many more red dots (monsters) on your map.
The goal is to place down Scout Towers on the junction points so that they can target monsters moving along multiple lanes. The map on the right shows the recommended locations for Scout Towers with Stars. |
| 17 | 
|
As you can see, monsters on the right are moving upward, so we need to build at least 2 Scout Towers next to the lane to tackle them.
Run around the map placing towers in this way. If the monsters are breaking through, build more towers in that region. |
| 18 | 
|
After you are done with building towers in all the main regions of the map, return to the center, and attack any monsters that break through.
You will be expected to deal a high amount of single-target damage for the mini bosses that spawn, as the towers may damage them but often fail to kill them. |
| 19 | 
|
When you have killed all the monsters, the encounter will end and the central drops will appear on the ground. These are usually of low value. |
| 20 | 
|
Run to the Blight Reward chests and loot them. This is where the primary profit comes from. |
