Adrenaline Rush

Player Guide: Harnessing the Power of “Adrenaline Rush” in Infinity Kingdom

“Adrenaline Rush” stands out as a quintessential skill within the Tower of Knowledge in Infinity Kingdom, renowned for its capacity to significantly enhance energy regeneration. This skill is a game-changer from the early stages of the game through to the late and end-game, offering strategic depth and versatility across various immortal lineups.

For a long stretch of Infinity Kingdom’s life, Adrenaline Rush was the go-to budget energy regen skill. It didn’t matter if you were a low-power free-to-play player or someone pushing Chaos teams — if you wanted your Immortals to fire ultimates faster, you slapped Adrenaline Rush on them and called it a day. It was cheap, reliable, and honestly one of the easiest ways to smooth out awkward energy curves.

Then patch 2.8.1 happened, and the skill got clipped pretty hard. The devs knocked down its flat energy bonus by a third, and from that point on, players had to actually think about when Adrenaline Rush was worth running — instead of just auto-including it.

This guide breaks down how Adrenaline Rush works now, why the nerf changed its place in the meta, and where it still has a purpose if you play it smart.

Understanding the Skill – How Adrenaline Rush Works

“Adrenaline Rush” operates under a simple yet powerful premise: “Every Normal Attack has a 50% chance of gaining 100 extra Energy.” (post nerf) This mechanic essentially boosts the energy gain rate, enabling immortals to execute their ultimate abilities more frequently. This attribute is especially beneficial for immortals whose combat effectiveness is heavily reliant on their ultimate skills.

Please make note of the wording, NORMAL ATTACKS. This skill cannot trigger off of other ToK skills, hits from ultimates, or anything else than simple normal attack damage instances. These are performed automatically by ALL immortals at varying speeds.

Patch 2.8.1 – What Actually Changed

Pre-Nerf Formula (Before Patch 2.8.1)

  • Base: 45
  • Per level: +15
  • Max level: 150 energy per proc

This was strong enough that even slow attackers or clunky supports could cycle ults way faster than they were designed to.

Post-Nerf Formula (Patch 2.8.1 and after)

  • Base: 30
  • Per level: +10
  • Max level: 100 energy per proc

The 50% trigger chance stayed the same, but that reduction from 150 → 100 made a huge real-world difference, especially for Immortals who:

  • attack slowly,
  • don’t have natural attack speed steroids,
  • or already had good energy regen and didn’t need flat boosts.

So the skill still works — just not for everyone, and not in every scenario.

Flat energy is at its best on slow Immortals.
Percentage-based energy bonuses are best on fast Immortals with naturally high regen.

By cutting the flat energy gain, the devs basically crippled the Immortals who relied on AR to “patch up” weak natural energy regen.

Who Lost the Most

  • Supports (Mathilda, Cyrus, Fu Fei)
  • Control/utility Immortals with slow basics
  • Any Immortal whose kit needed their ult to function normally

Who Still Gains Something

  • Fast attackers (Hippo-style setups)
  • Builds using attack-speed buffs
  • Back-up marches where you’re just trying to squeeze extra ult cycles from low-investment tanks or bruisers

Strategic Synergies

Energy Regen 101 – The System Behind the Skill

To understand who AR works on now, you have to understand how energy regeneration actually works.

Every Immortal regens toward 1000 energy to cast an ultimate from two sources:

1. Base energy regen (the passive gain)

Can be boosted by:

  • Lord talents (ex: Owl Guardian, +5% regen)
  • Academy research
  • Surge-based artifact attributes
  • Skills like Rage Blessing or Battle Stance

These % multipliers work best on Immortals who already have high energy regen attribute (see immortal attribute panel).

2. Energy from Tower of Knowledge Skills

This is where Adrenaline Rush, Energy Burst and newer skills like Energy Master and Corrosive Power comes into play. In the right build you can supercharge your energy regen through trigger-effects.

They add flat energy — which benefits slow Immortals more because they swing fewer attacks, so every proc matters a lot more.

Skills such as “Energy Burst,” “Full Coverage,” “Corrosive,” and even ultimates such as e.g. Hippolytta’s or Seondeok’s benefit from the increased energy regeneration, leading to more frequent activations and a cascading effect of enhanced battlefield control and/or damage output.

Good Skill Pairings After the Nerf

This is where the skill still has some life, depending on the build you’re running.

Wind Rage + Adrenaline Rush

Wind Rage adds extra normal attacks → more chances to proc AR.
Still one of the better combos if you’re trying to boost ult cycling without using expensive regen skills.

Speed Blessing + Adrenaline Rush

Great for front-loading your early fight tempo.
The boosted initial attack speed helps AR trigger early when the fight tempo matters most.

Berserk (Aura) + Adrenaline Rush

Not flashy, but the permanent 10% attack speed means steady proc chances.
Better in drawn-out fights.

Fighting Master + Adrenaline Rush

If your Immortal keeps getting stunned or rooted, AR is worthless.
Fighting Master fixes that and keeps your attack rhythm stable enough to trigger AR consistently.

This combo is mostly for tanks or bruisers in secondary marches.

Good to know: Ways to disrupt enemy regen

Because regen is so core to the game, there are tools that mess with it:

  • Energy Suppression (brutal early-game impact)
  • Silence, stun, freeze, root (interrupts swings → fewer energy gain chances)
  • Dodge skills like Misleading (you can’t gain energy from a swing that never lands)

Where Adrenaline Rush Still Makes Sense

After testing it post-nerf, the pattern is pretty consistent:

Still decent on:

  • Fast attackers
  • Ultimate reliant Immortals stacked with attack speed buffs
  • Defensive frontliners in non-primary marches, e.g. AR is still good on a Charles in your second or third.
  • Any Immortal whose alternative skill choices are low-level or off-theme
  • On control immortals who does not do well with damage skills, hence Burst or Energy Master would be terrible value, but AR can be good e.g. on a Tomyris in order to try and squeeze one more Confusion into a battle (check if it lines up in your combat encounters). Same principle for healers like Zenobia in a second or third march. Just to be clear though, this is where its useful.. it is NOT the optimal skill, hence second/third march recommendation.
