The **Aegires** is a Tier 4 support Naval Unit on Serpulo, obtained when the Cyerce is upgraded in the Exponential Reconstructor. It carries no damaging weapons and instead wields an energy field that zaps up to 25 enemy or friendly targets, damaging or repairing them respectively. Friendly units and structures are healed by a small percentage of their maximum health. Enemies that are zapped are inflicted with the Electrified status for 6 seconds, which decreases fire rate by 40% and movement speed by 30%. It also carries four Segment-like point defense turrets that destroy incoming physical bullets.

Aegires can be upgraded into the Navanax in a Tetrative Reconstructor, by attaching reconstructors directly or by being dropped in by a payload-carrying unit, such as the Oct.

## Weapons

*\*Aegires has two sets of this weapon with 2x 7.5 fire rate each, but are grouped as one for simplicity due to having identical stats*

## Strategy

### Against

The energy field of the Aegires is rather insidious, as it will rapidly destroy puny Conveyors and Power Nodes with just a few ticks, shutting down your entire defense. Attempting to kill it from afar with the Ripple is ineffective as its damage is low and its bullets can be destroyed by the point defense systems. Luckily, Plastanium Walls will block the field and protect your fragile blocks, at which point a powerful, non-projectile turret like the Fuse or Foreshadow can do its work. It is also important to note that repairing units like the Poly and Mega are very fragile and can perish in the field unless it is blocked off.

The problems compound when paired with other offensive units, especially the Sei. To make sure the Plastanium Walls only receive laser damage, place an outer layer of Thorium Walls to soak up bullets as well. Because the Sei is more likely to cause a breach (and let the field infiltrate into your conveyors), it should be focused on first by your strongest turrets. Sending your own units is ill-advised due to the field's status effect, which severely hampers your damage.

### For

The main caveat to using the Cyerce for healing is that they are fragile compared to their accompanying Tier 4 units. With the Aegires, this problem is solved and now you can create self-regenerating death balls, which are very difficult to stop. This opportunity is most present in long PvP matches with water, as the Sei without support can easily handle campaign bases.

On defense, the Aegires can provide strong healing and support but is very expensive to build. The healing is primarily based on a percentage, which will leave lower-health blocks like the Overdrive Dome easily destroyed as they restore less raw health per tick. The segments are also rather useful as they do not need power. Most importantly, the field's status effect significantly increases your survivability by reducing the fire rate of enemies to only 60% of its original value. Since no turret can be placed in deep water, the Aegires is ideal for watery survival maps, especially as it can be moved around by an Oct to travel across land.

## Changes

 Version 7.0, Build 128 | * Speed converted from 0.7 arbitrary units to 5.25 tiles/second.
 Version 7.0, Build 129
 Version 7.0, Build 130
 Version 7.0, Build 132
 Version 7.0, Build 136 | * Range increased (4 blocks → 22).
* Command limit of 8 removed.
* Energy field damage increased (35 → 40).
* Energy field healing percentage increased (2.5% → 3%).
 Version 7.0, Build 146 | * Energy field healing percentage decreased (3% → 1.5%).
* Energy field ability now has a -50% Same Type Healing modifier. This means Aegires will only be healed by 0.75% at a time from another Aegires energy field.
* Point defence turret damage increased (25 → 30).
* Point defence turret fire rate increased (5 shots per second → 7.5).
	+ The above changes apply for all the point defence turrets.

## Trivia

* Aegires is named after the *Aegires* genus of Nudibranchs, which feeds exclusively on sea sponges.
* Aegires currently has the highest health out of all Tier 4 units, at 12000.
* Due to the energy field using percentage healing as opposed to a flat number, the units that benefit the most from getting healed by Aegires are the Reign and Oct at (24,000 health x 1.5% = 360) health per zap.
