Trivia

Aak is a 6★ Geek Specialist who specializes in Support and DPS. Aak is unique among Operators where his HP "degenerates" (i.e. gradually lost) at a rate of 3% of his maximum HP per second, which can knock him out. Unlike most other Specialists, Aak is classified as a ranged Operator with a ranged attack similar to Marksman Snipers, including a range of 3×3 with a 1×1 extension up front that is extended to 3×4 at Elite 1, which also (somewhat) extends to his stats.

Talents

1. Drug Cocktail Administration applies one of the following effects in each attack, selected at random:
   • Heals Aak by a portion of his maximum HP.
   • Increases the damage dealt.
   • Briefly Slows the target.
   • Briefly Stuns the target.
2. Pharmaceutical Diffusion amplifies healing received by Aak.

Skills

Aak's skills are very unusual in which all but one of them allows him to buff friendlies by attacking them first — the only known way of causing "friendly fire" in Arknights, which can knock out the target if they cannot withstand it!

1. Rapid Fire buffs Aak's ASPD while active.
2. Type-γ Stimpack has Aak attack a friendly unit within his range, prioritizing the one right in front of him, with 15 hits that deals 500 Physical damage each when activated, and buffs the maximum HP and DEF of the target (if they survive, of course) and Aak himself (regardless of whether the target survives or not) after he finishes attacking for a period of time.
   • Type-γ Stimpack is best used on Defenders since their high DEF means Aak's attacks will only scratch them while improving their already good survivability even further, especially with strong Defenders like Hoshiguma, Mudrock, and Nian who will be nearly invincible with the buff.
   • It is ill-advised to use Type-γ Stimpack on Operators with low HP and/or DEF (like most ranged Operators) since they will usually be KO'd in the process.
3. Durian-Flavored Stimpack is identical to Type-γ Stimpack but buffs the ATK and ASPD of Aak and the target instead.
   • Durian-Flavored Stimpack can be very tempting to bolster the DPS of already hard-hitting Operators, especially Blaze (with Chainsaw Extension Module), Hellagur (due to his talent which buffs ASPD based on the missing HP), SilverAsh (with Truesilver Slash), Skadi (with Tidal Elegy), Specter (with Bone Fracture), Młynar (with Unbrilliant Glory), and especially Surtr (due to her colossal DPS with Twilight).
     • Even better, Blaze's Emergency Defibrillator and Surtr's Remnant Ash will temporarily keep them alive upon receiving fatal damage, including from Durian-Flavored Stimpack's shots, Specter straight up cannot be knocked out while Bone Fracture is active, and the massive max HP buff from Surtr's Twilight lets her survive easily, so it can be liberally used to give them titanic DPS.
   • Care should be taken, however, to be sure the Operator survives Durian-Flavored Stimpack's shots, as many high-DPS operators tend to have lower HP and DEF, and will get easily one-shot by Durian-Flavored Stimpack.
     • The player should try to buff the desired Operator's DEF first (preferably with Nian or Shining), give them Sanctuary with Abjurers, or other survival methods (e.g. Flametail's "Pinus Sylvestris", Silence the Paradigmatic's Dreadnought Protocol) before using Durian-Flavored Stimpack on them.

Operator Module

The GEE-X Module, Mixed-Fruit Medical Caddy, increases Aak's SP recovery rate by 0.25 per second so long as his HP is above 80% in addition to increasing his maximum HP and ATK. Once upgraded, Drug Cocktail Administration's effects are increased and it now has a chance to proc all four effects at once!

Base skills

1. Neuroticism makes Operators assigned to the Reception Room more likely to find clues from their respective faction (e.g. Rhine Lab clues for Saria) but increases the morale drain rate of Operators in the Control Center (including Aak himself) by a whopping 1.5 per hour while Aak is assigned there.
2. Surgical Precision speeds up the skill Specialization training of Medics by 60% while Aak is assigned as the trainer in the Training Room.

Summary

Aak is an interesting (and fun) introduction to Geek Specialists who can thrive on "high-risk, high-reward" playstyles by "juicing" up his allies' performance at the cost of harming – and potentially incapacitating – them, hence Doctors who want to utilize him should plan carefully to avoid collateral damage that could risk their defeat, but this mad doctor's buffs will surely get them addicted once they get the hang of it.
