Overview

With knowledge comes understanding, and with understanding comes mastery. The Biochemist's unyielding dedication to research and experimentation have raised them to the summit of scientific knowledge. Now that their proficiency with potions and chemicals is unmatched, they are on the verge of manipulating the very laws of nature!

Biochemists are a much stronger class than the Alchemists, provided there are sufficient funds and SP for the new skill Acid Demonstration (often abbreviated to "AB" or "AD" as it is known as Acid Demonstration on some other official servers.). While Alchemists were more of a melee class, Biochemists tend to level with skills other than Cart Revolution and Mammonite. Many invest a great amount of their stat ponts into INT and level with Acid Demonstration or magic attacks from weapons (i.e. Fire Bolt through the weapon Firebrand) and Homunculi instead.

Biochemists are a popular class in iRO because of the amount of damage they can deal, along with the current lack of methods to counter their offensive skills, when they are used properly.

Jobchange Guide

To become a Biochemist, you must find a book called 'the Book of Ymir' in 'Sage Castle', Juno. The book will lead you to Valhalla so you can change your job through the Biochemist job NPC. Also you must reach at least job level 40 as a transcendent 1st class character.

  • Note: After becoming a Biochemist, if the player knew Bioethics in their prior life, they can regain it by speaking to the Job Change NPC in Valhalla a second time.

Builds

Acid Demonstration (VIT)

  • STR: 1
  • AGI: 1
  • VIT: 70-80
  • INT: 99 (base)
  • DEX: 75-85+
  • LUK: 1

The VIT-heavy AB build gets the most out of the Alchemist skills Potion Pitcher and Potion Research. It's a good choice for soloing MVPs that stun or damage lock. This build can also make a good tank in WoE.

Suggested skills are Acid Demonstration Lv. 10, Potion Pitcher Lv. 5, Potion Research Lv. 10, Homunculus Resurrection Lv. 1, and either Full Chemical Protection Lv. 5 or Slim Potion Pitcher Lv. 10 ,Armor/Weapon/Shield/Helm coatings all at Lv. 3, or Full Chemical Protection.

Acid Demonstration (DEX)

  • STR: 1
  • AGI: 1
  • VIT: 1-70
  • INT: 99 (base)
  • DEX: 95-149
  • LUK: 1

The DEX-heavy AB build maximizes damage output with Acid Demonstration. They aim to cast Acid Demonstration faster than their MVP competition or while attacked by other players without the cast being interrupted.

The skills suggested are the same as for the VIT version. Though, the Chemical Protections aren't as important for this type of character; instead, consider Bio Cannibalize and Slim Potion Pitcher.

At 150 dexterity, the bombing rate is slower than 149 Dexterity despite being instant cast due to the introduction of an irreducible delay. To bomb as quickly as possible, it would be ideal to have 149 Dexterity, 190 attack speed, and be in A Poem of Bragi.

AB/Potter

  • STR: 1
  • AGI: 1
  • VIT: 40-60
  • INT: 93-99 (base)
  • DEX: 66-76 (base)
  • LUK: 37-67(base)

This Biochemist build is built for WoE, and at the same time, enjoys good potting success. (base pot success chance of abt 75%-80% at max job level) The LUK also makes up for the lack of high VIT for status resistance in WoE. LUK also helps in resisting effects such as Frozen status and Stone, which can be devastating in WoE. Low VIT also means that this class is also good for taking on other Biochemist's Acid Demonstration.

Potter (MC)

  • STR: 1
  • AGI: 1
  • VIT: 1
  • INT: 94-99 (base)
  • DEX: 36 (base)
  • LUK: 94-99 (base)

A Biochemist built for Pharmacy should be built for Marionette Control to maximize the success rate. Getting 99 base INT rather than DEX can be preferable as it boosts Acid Demonstration damage considerably and lowers the Pharmacy success rate by only \~0.25%.

Hybrid

If the concept of making a character primarily dependent on one skill is not appealing, Biochemists can also be built like a normal battle Alchemist. Invest stat points into STR and AGI but be sure to keep INT in mind for Acid Demonstration. Fair warning though, a significant drop in INT will cause the damage of Acid Demonstration to drop.

Tactics

PvM

Acid Demonstration while expensive yields good exp-rates (20m exp/hour) in maps like Thanatos Tower and Biolabs 3. Try to get a Priest to cast Lex Aeterna on the monster first though. Slaves are affordable compared to the 10m zeny+ per hour of leveling costs for this method.

MVP

The cost of Acid Demonstration is overcome by the zeny gained from MVPing while solo or in small parties. A Biochemist will usually beat the competition on almost any MVP. With enough VIT, it's possible to solo MVPs that most people have trouble tanking.

PvP

Acid Demonstration will one-shot a considerable amount of players in PvP.

WoE

A Biochemist is an excellent tank, has access to Chemical Protections and can kill the enemy tanks with ease. They, along with a properly scripted AI for their Homunculus, are one of the best WoE-classes.

Equipment

A Biochemist built for Acid Demonstration should aim for equipment that adds INT or, sometimes, that gives a significant amount of DEX. However, these equipments are a general guide.
