Blight tower | PoE Wiki (2024)

Blight towers can be constructed during Blight encounters. There are several different types of towers, each with different effects and upgrades.

Tower types

Some enemies can either resist or be immune to a certain tower types.

Cold towers slow enemies action speed and deal cold damage. They have a short range.
Fire towers deal fire damage. They have a long range.
Physical towers stun or slow enemies action speed. They also deal physical damage.
Lightning towers deal lightning damage. They can also shock.
Aura towers primarily upgrade other towers. They can also upgrade players, but not minions. The exception to this rule is minions coming from aura upgraded towers. Aura towers can only upgrade each tower once. Multiple aura towers will not upgrade the same tower. Tower auras upgrade other towers, but not themselves when near each other.
Minion towers create minions that can block enemies paths. Not all enemies will be blocked by minions. Some enemies can use movement skills around minions.

Tower upgrades

Options

All 6 tower types begin at tier 1. They remain the same kind of tower for tier 2 and 3 tier upgrades. Upgraded versions of the same tower do more damage, hit more often, have more range and have less cooldown time. There are 2 tier 4 options available. This means there are 18 total options of towers to choose from.

Cost

Tower cost per upgrade from tier 1 to 4 is 100, 150, 300, 500.

Total cost of each tier tower from tier 1 to 4 is 100, 250, 550, 1050.

Every tier 4 tower is the same total cost as 10.5 tier 1 towers.
Every tier 3 tower is the same total cost as 5.5 tier 1 towers.

Tower Range

All towers will only work within a limited radius of the character. For example:

On a blighted map, if a character makes a bunch of towers to defend the center and then moves to kill enemies far away at the edge of the map, the towers in the center will not be active and they can cause the player to lose the encounter.

Anointments

Tower effects can be modified by anointments on rings. For the entire list with oil requirements see List of ring anointments. All anointments can be used twice with 2 different rings to double their effects when possible. In a party, a tower belongs to the player that created or most recently upgraded it, using only that player's anointments.

Noteworthy anointments

Your Chilling Towers freeze enemies for 0.2 seconds while they are affected by chilling beams Opalescent OilOpalescent OilStack Size: 10
Oil Tier: 11Can be combined with other Oils at Cassia to Enchant Rings or Amulets, or to modify Blighted Maps. Silver OilSilver OilStack Size: 10
Oil Tier: 12Can be combined with other Oils at Cassia to Enchant Rings or Amulets, or to modify Blighted Maps. — This modifier has no cooldown. With level 3 chilling tower next to a level 3 imbuing tower enemies will be frozen permanently. Chilling tower has a target limit, so it will not freeze massive numbers of enemies. There are some rare enemies that are immune to chill or action speed that will not be frozen.
Your Temporal Towers also grant you 20% increased action speed Golden OilGolden OilStack Size: 10
Oil Tier: 13Can be combined with other Oils at Cassia to Enchant Rings or Amulets, or to modify Blighted Maps. Teal OilTeal OilStack Size: 10
Oil Tier: 5Can be combined with other Oils at Cassia to Enchant Rings or Amulets, or to modify Blighted Maps. — For calculation this is equal to 20% more multiplier for movement, attack and cast speed. 2 of them is 40% more. This will only affect you and not your minions or other players.
Your Fireball Towers fire an additional 8 Projectiles. Your Fireball Towers Projectiles fire in a circle Golden OilGolden OilStack Size: 10
Oil Tier: 13Can be combined with other Oils at Cassia to Enchant Rings or Amulets, or to modify Blighted Maps. Opalescent OilOpalescent OilStack Size: 10
Oil Tier: 11Can be combined with other Oils at Cassia to Enchant Rings or Amulets, or to modify Blighted Maps. — 8 extra fireballs and fireballs shoot in a circle instead of aiming at enemies. Fireball towers already have a long range and this gives them even more area to cover with extra projectiles and targeting change.
Your Flamethrower Towers deal full damage to Fire Enemies Crimson OilCrimson OilStack Size: 10
Oil Tier: 9Can be combined with other Oils at Cassia to Enchant Rings or Amulets, or to modify Blighted Maps. Violet OilViolet OilStack Size: 10
Oil Tier: 8Can be combined with other Oils at Cassia to Enchant Rings or Amulets, or to modify Blighted Maps. — Most towers have 1 blight enemy that greatly resists their damage type, making them nearly useless for damage. This anointment removes that problem for players who do all their damage with flamethrower towers.
Your Meteor Towers always Stun Crimson OilCrimson OilStack Size: 10
Oil Tier: 9Can be combined with other Oils at Cassia to Enchant Rings or Amulets, or to modify Blighted Maps. Crimson OilCrimson OilStack Size: 10
Oil Tier: 9Can be combined with other Oils at Cassia to Enchant Rings or Amulets, or to modify Blighted Maps. — Will not stun as often as seismic towers, but allows players to stun with fire damage instead of physical. Also meteor has a much longer range than seismic towers.
Your Meteor Towers drop an additional Meteor Opalescent OilOpalescent OilStack Size: 10
Oil Tier: 11Can be combined with other Oils at Cassia to Enchant Rings or Amulets, or to modify Blighted Maps. Verdant OilVerdant OilStack Size: 10
Oil Tier: 4Can be combined with other Oils at Cassia to Enchant Rings or Amulets, or to modify Blighted Maps. — This is the highest tower damage for 1 anointment. 1 anointment doubles your damage, since the base is 1 meteor. anointing a second time is equal to 50% more damage, since you already fire 2 after the first anoint.
Your Meteor Towers create Burning Ground for 3 seconds on hit Indigo OilIndigo OilStack Size: 10
Oil Tier: 7Can be combined with other Oils at Cassia to Enchant Rings or Amulets, or to modify Blighted Maps. Violet OilViolet OilStack Size: 10
Oil Tier: 8Can be combined with other Oils at Cassia to Enchant Rings or Amulets, or to modify Blighted Maps. — This is relatively cheap but powerful anointment that greatly increases damage over small congested area. Since source of damage inflicted by Burning Ground is the Burning Ground itself, rather than a tower, its damage is unaffected by fire tower immunity on mobs.
All Towers in range of your Empowering Towers have 50% chance to deal Double Damage Golden OilGolden OilStack Size: 10
Oil Tier: 13Can be combined with other Oils at Cassia to Enchant Rings or Amulets, or to modify Blighted Maps. Golden OilGolden OilStack Size: 10
Oil Tier: 13Can be combined with other Oils at Cassia to Enchant Rings or Amulets, or to modify Blighted Maps. — This is the second highest tower damage anointment and it affects all tower types instead of just meteor tower only.
