Uncharged - Primus Conduit is not functional, it is not affecting the firing speed of connected defenses.
Charged - Connected defenses have X% firing speed increase, as per the 'Charged Increase' column above (up to 24hrs).
Over-charged - Connected defenses have X% firing speed increase, as per the 'Over-charged Increase' column above (up to 24hrs).
Extended Over-charge - Connected defenses have X% firing speed increase, as per the 'Over-charged Increase' column above (up to 48hrs).

Technical Overview

The Primus Conduit can increase the attack speed of the following defenses:

Defensive buildings must directly connect to at least 2 tiles of the Primus Conduit edge in order to receive the increase. You can connect a defense to 2 Primus Conduits at the same time, which will give you a multiplied increase in fire speed.

Calculations

To calculate attacks per second:
defense attack speed x (conduit boost [x conduit boost])

To calculate attack speed:
defense attacks per second / (conduit boost [x conduit boost])

Example 1:
An Arrow Launcher has a rating of 0.33 attacks per second (1 attack every 3 seconds [calc: 1/0.33]).
The Arrow Launcher is connected to:
A level 5 over-charged Primus Conduit, which will increase the attack speed by 48%.
To calculate the Arrow Launchers new attack speed: 0.33 x 1.48 = 0.49 attacks per second (1 attack every 2.04 seconds [calc: 1/0.49]).

Example 2:
An Arrow Launcher has a rating of 0.33 attacks per second (1 shot every 3 seconds [calc: 1/0.33]).
The Arrow Launcher is connected to:
A level 5 over-charged Primus Conduit, which will increase the attack speed by 48%.
A level 8 over-charged Primus Conduit, which will increase the attack speed by 54%.
To calculate the Arrow Launchers new attack speed: 0.33 x 1.48 x 1.54 = 0.75 attacks per second (1 attack every 1.33 seconds [calc: 1/0.75]).

Example 3:
The base attack speed of a level 1 Spell Tower is 0.1 (1 attack per 10 seconds).
A level 8 Spell Tower increases the attack speed by 40%, so that's an attack speed of 0.1 x 1.4 = 0.14 attack speed (1 attack every 7.14 seconds [calc: 10 / 1.4]).
The Spell Tower is connected to:
A level 7 over-charged Primus Conduit, which will increase the attack speed by 52%.
A level 9 over-charged Primus Conduit, which will increase the attack speed by 56%.
To caclulate the Spell Towers attacks per second: 0.14 x 1.52 x 1.56 = 0.332 attacks per second.
To calculate the Spell Towers attack speed: 7.14 / (1.52 x 1.56) = 1 attack every 3 seconds (calc: 1 / 0.332).


Placement Examples

primus1-charged.png
Catapult is boosted by the Primus Conduit
primus6-charged.png
Catapult is NOT boosted by the Primus Conduit (1 tile gap between the 2 structures)
primus2-charged.png
Catapult is boosted by the Primus Conduit
primus3-charged.png
Catapult is NOT boosted by the Primus Conduit (only 1 tile connecting, need 2-3 tiles connected)
primus4-charged.png
Catapult is NOT boosted by the Primus Conduit (no tiles are connected, need 2-3 tiles connected)
primus5-charged.png
Catapult is boosted by 2 Primus Conduits (charged amount is multiplied by 2 conduits)

Tip: If the defense sparkles, it's being powered by the Primus Conduit!

Mithril Upgrades and costs

There are three Mithril upgrades to choose from:

1. Regen: While overcharged, the Conduit and its targets recover 50 health a second. Increases overcharge cost by 50% and cannot stack.
2. Protect: While overcharged, The Conduit and its targets take 35% less damage from troops. Increases overcharge cost by 50% and cannot stack.
3. Shell: While overcharged, the Conduit and its targets take 45% less damage from spells. Increases overcharge cost by 50% and cannot stack.

Mithril upgrade costs, once you have invested in an upgrade tree (see below) you are locked into it. To invest you must pay the Mithril and ring cost which scales based in points already invested:
