Changes: Heat Sink

Revision as of 01:43, 3 July 2020

As a temporary gameplay change, starting March 19th, 2020, the Portal cooldown has been reduced from the standard five minutes to 90 seconds. All cooldowns are reflecting the change.

The Heat Sink is a portal mod. Its multiple effects assist agents in Hacking the equipped Portal.

Effects of 1 Heat Sink on Portal
Rarity	Hack Speed	Cooldown
(None)	0%	1:30
Common	+20%	1:12
Rare	+50%	0:45
Very Rare	+70%	0:27

All Heat Sinks have the following effects:

For all players: Reduces the Portal's cooldown, for all players allowing it to be hacked more frequently (excluding burnout). See the table above.
For the deploying agent: Resets the cooldown and burnout timers, so he or she can immediately Hack the Portal again.

Rarities

Heat Sinks are available in Common, Rare, and Very Rare rarities, which affect the cooldown reduction the item bestows. Community studies estimate the drop rates to be 1 in 100, 500, and 5500 item rolls, respectively.

All Heat Sinks have 0 Stickiness.

Players often refer to Heat Sinks using an abbreviation. 'CHS', 'RHS', and 'VRHS' refer to a Common, Rare, and Very Rare Heat Sink, respectively.

Cooldown Reduction

Rarity	Hack Speed	Cooldown
Common	+20%	1:12
2 × Common	+28%	1:04
3 × Common	+35.2%	0:58
4 × Common	+41.7%	0:52
Rare	+50%	0:45
2 × Rare	+62.5%	0:33
3 × Rare	+71.9%	0:25
4 × Rare	+78.9%	0:18
Very Rare	+70%	0:27
2 × Very Rare	+80.5%	0:17
3 × Very Rare	+87.3%	0:11
4 × Very Rare	+91.8%	0:07

A single Heat Sink decreases the cooldown time of the equipped Portal, reducing the time before an agent can Hack the Portal again. The effect applies to both allied and enemy agents. If an agent's remaining cooldown is less than the new cooldown after a Heat Sink is applied, the agent can immediately Hack the Portal again.

When multiple Heat Sinks are attached to the same Portal, the rarest Heat Sink applies its full effect. Each subsequent Heat Sink's effect is halved, from highest to lowest rarity. The cumulative effect can be calculated using the following formula:

((1-h)*(1-a/2)*(1-b/2)*(1-c/2))*90

h = Rarest Heat Sink decrease percentage
a = Second rarest Heat Sink decrease percentage
b = Third rarest Heat Sink decrease percentage
c = Fourth rarest Heat Sink decrease percentage

For an example, a group of agents deploys 1 Very RareHeat Sink, 2 RareHeat Sinks and 1 CommonHeat Sink:

((1-0.7)*(1-0.5/2)*(1-0.5/2)*(1-0.2/2))*90 = 13.67 seconds between hacks

Cooldown/Burnout Reset

When an agent attaches any Heat Sink to a Portal, regardless of rarity, he or she can immediately Hack the Portal again, resetting both the Cooldown and Burnout. This effect applies only to the agent who attached the Heat Sink.

The agent can now Hack the Portal a number of times equal to its burnout count (depending on deployed Multi-hacks). A new four-hour burnout recovery timer will begin when the agent completes the next Hack on the Portal.

This effect is not cancelled when the mod is destroyed in an enemy attack.

Strategy

The cooldown reduction is most relevant when a large number of agents have limited time to Hack a Portal. This makes Rare and Very Rare Heat Sinks crucial parts of "Powerhacks", or intensive hacking sessions, where the risk of enemy sabotage is high.

Because cooldown reduction serves only to reduce the total time it takes to burn out the Portal, the effect is irrelevant if agents have time to spare, if they can use the cooldown time efficiently, or if they can easily return after the burnout period elapses. Deploying a Heat Sink in these circumstances serves only to waste a mod slot.

The cooldown reset is useful for hacking the same Portal repeatedly in close succession, such as when acquiring Portal Keys.

The burnout reset synergizes well with Multi-hacks. Because the Multi-Hack's effects are applied to each burnout/reset cycle, its effect will be multiplied for the agent who attaches the Heat Sink. To maximize yield, the Multi-Hack should be applied first, with the Heat Sink applied only after the agent has burned the Portal out. Theoretically, an agent can perform 64 Hacks in 2 hours 10 minutes using this method with 1 Very Rare Multi-Hack and 3 Very Rare Heat Sinks.

If an enemy is attacking a Portal, an agent can continuously attach new Common Heat Sinks as the old ones are destroyed, so as to Hack the Portal repeatedly in close succession. In a pinch, an agent can even use a Flip Card to switch the Portal to the opposite side, destroy it, recapture it, and apply fresh Heat Sinks for additional Hacks.

Rare or Very Rare Heat Sinks attached to high-level enemy Portals are often telltale signs that enemies have gathered to rapidly 'farm' resources. Savvy agents will disrupt these Powerhacks and stake out the area to deny resources to the opponents.

Trivia

The maximum cooldown decrease is 91.76% and that is seven seconds. This can be achieved with 4 Very Rare Heat Sinks.

Usage

An agent of any level can deploy a Heat Sink by expending XM depending on the item's rarity.

Heat Sink Rarity	XM Cost
Common	400 XM
Rare	800 XM
Very Rare	1000 XM

+A single Heat Sink decreases the cooldown time of the equipped Portal, reducing the time before an agent can Hack the Portal again. The effect applies to both allied and enemy agents. If an agent's remaining cooldown is less than the new cooldown after a Heat Sink is applied, the agent can immediately Hack the Portal again.
-When combining various rarities, the cooldown time decrease can be calculated using the following formula:
-<pre>300 - (1-(1-h)(1-a/2)(1-b/2)(1-c/2))*300
+When multiple Heat Sinks are attached to the same Portal, the rarest Heat Sink applies its full effect. Each subsequent Heat Sink's effect is halved, from highest to lowest rarity. The cumulative effect can be calculated using the following formula:
-h = Most rare Heat Sink decrease percentage
-a = Second Heat Sink decrease percentage
-b = Third Heat Sink decrease percentage
-c = Fourth Heat Sink decrease percentage</pre>
+<pre>((1-h)*(1-a/2)*(1-b/2)*(1-c/2))*90
-Example: an agent deploys 1 VERY_RARE Heat Sink, 2 RARE Heat Sinks and 1 COMMON Heat Sink.
-<pre>300 - (1-(1-0.7)(1-0.5/2)(1-0.5/2)(1-0.2/2))*300 = 45.56 seconds</pre>
+h = Rarest Heat Sink decrease percentage
-==Reset Burn Out Timer==
+a = Second rarest Heat Sink decrease percentage
-Typically you only get 4 hacks on a portal before burning it out. Multihacks of course add onto the burnout counter, allowing any Agent to hack beyond it’s burnout limit. Heat Sinks (regardless of rarity) now reset the burnout period to 0 for the Agent that installed the mod.
+b = Third rarest Heat Sink decrease percentage
-This reset is only a one time reset of the burnout counter for the Agent that installed the mod.
+c = Fourth rarest Heat Sink decrease percentage
-Example 1:
+</pre>
-I’ve hacked a portal 4 times and burned it out. Adding a Heat Sink resets that burnout counter to 0, allowing me to hack 4 more times, with a total of 8 hacks. Other Agents still only get their original 4 hacks with no burnout reset.
-Example 2:
-I’ve installed a Common Multi Hack and hacked a portal 8 times before burning out the portal. Adding a Heat Sink will reset that counter to 0, allowing me to hack 8 more times.
+For an example, a group of agents deploys 1 {{rarity|4}}Heat Sink, 2 {{rarity|3}}Heat Sinks and 1 {{rarity|2}}Heat Sink:
