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 Bomb (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 have the option to level with a skill other than Cart Revolution and Mammonite. Many invest a great amount of their stat points into INT instead of AGI, and level with Acid Bomb or magic attacks from weapons (i.e. Fire Bolt through the weapon Fireblend) and Homunculi instead.

Biochemists are a popular class in iRO because of the amount of damage they can deal to MVPs in particular, as well as because their third job class Geneticist is a handy and capable character in War of Emperium.

Job Change 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.

1.Sage Castle is located at 11 o'clock direction (yuno 88,320) in Juno.	2.'Book of Ymir' is located inside a room behind an NPC called Metheus Sylphe (yuno_in02 88,164).
3.The Book of Ymir (yuno_in02 94,206) will teleport you to Valhalla.	4.Find and talk to a job NPC suited to your 2nd class.

• 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

AGI/Melee Build

• STR: 90
• AGI: 90
• VIT: 16
• INT: 26
• DEX: 46
• LUK: 2

If the concept of making a character primarily dependent on killing boss monsters with expensive reagents is not appealing, Biochemists can be built like a normal battle Alchemist. Invest stat points into STR and AGI but be sure to keep some INT in mind for Acid Bomb.

With the stats, the direction you are going there is enough STR to do heavy damage (especially with a Heroic Backpack) with either melee attacks, Cart Revolution, or Mammonite. The high attack speed granted by the large amount of AGI will make spamming Mammonite or melee attacking much quicker. A +9 Heroic Backpack confers both +8% ASPD and +1 ASPD (a flat bonus) when the Biochemist has 90 base AGI or higher. It is strongly recommended to use the merchant's Medal of Honor with this build, as they are accessories that enhance ASPD by +10% each. A difficult to procure substitute would be the Bakonawa Agimat Tattoo, as it also increases ASPD by 10% each.

This build is designed with the intention of using a free stat reset in the Eden Group (the Mesmerist behind the counter on the left) to remove the AGI from your build once you are a Geneticist.

Useful Gear for AGI Builds:

• Snake Head [1] or Chick Hat
• Musketeer Hat
• CD in Mouth
• Heroic Backpack
• Ring of Flamelord
• Medal of Honor or Bakonawa Agimat Tattoo

Acid Bomb Leveling

• STR: 90
• AGI: 1
• VIT: 26
• INT: 90
• DEX: 50
• LUK: 1

Since you will not be doing War of Emperium on such a low-leveled character, VIT is a low priority. Since it costs very little early on to start getting a stat, it is a bit more handy to get 25 VIT than it is to get only 10 more DEX. Since DEX doesn't contribute much to Acid Bomb it is also treated as a low priority. You will need the DEX early on as a high merchant, and you will need it eventually as a Geneticist, so right now you're just building up the stat-- you're not going to need it as a Biochemist necessarily.

The goal with this build is to level by means of MVPing. That is to say, throw Acid Bombs at MVP monsters to get your experience. MVP monsters are unique in that their experience rewards, while high, are not adjusted by the level difference between the two of you. This makes leveling quite rapid if you are prepared properly for it, and can queue up a string of MVP monsters to kill (Bloody Branches being the best way).

The 90 base STR and 90 base INT allow for optimal use of the Heroic Backpack item. The Heroic Backpack, when +9 or higher, allows a 90 base STR and INT character to receive +30 ATK and +50 MATK, both highly valuable to Acid Bomb. Later on, when you can get DEX to 90, you'll be able to also pick up a +10% ranged damage bonus (which affects Acid Bomb) as well. Another reason to get STR high is that STR serves to amplify the base ATK of any weapon you wield. Biochemists are able to equip some excellent high-attack weapons like the Hurricane Fury, which provides a high amount of attack power with a high STR score.

Potter (MC)

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

A Biochemist built for Prepare Potion should be built for Marionette Control to maximize the success rate.

Tactics

Leveling

• Acid Bomb while expensive yields good exp-rates against MVP monsters. Try to get a Priest to cast Lex Aeterna on the monster first, though, to save you some money on the consumable items required for the skill.
• An AGI build can solo maps such as Juno field 4, which has a lot of the low HP Harpy monster. Veins Field 3 for Magmarings is also a good spot.
• A more supportive Biochemist might find a place in a party with other players using the Aid Potion skill.

MVP

The cost of Acid Bomb 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. It is highly recommended to pair up with a High Priest or preferably an Arch Bishop when working on MVP monsters, as most MVP monsters are balanced for combat with 3rd job characters in mind. Arch Bishops are particularly helpful, as their skill Sacrament will significantly improve the cast time of Acid Bomb.

PvP

Acid Bomb will deal a lot of damage to some players in PvP, particularly those not wearing a lot of demi-human or ranged reduction. A player fully geared with a "WoE Set" will often take very low damage from acid bomb, however. It is not recommended to PVP on a character below 3rd job, as much of your competition will likewise be 3rd job characters.

WoE

A Biochemist has access to Full Chemical Protection which is useful to allies in War of Emperium.

Equipment

A Biochemist built for Acid Bomb should aim for equipment that adds ranged Damage icnreases, but failing that anything that adds MATK/INT or ATK/STR. Defensive equipment versus MVP monsters is also vital.

Weapon Choices:

• Mjolnir (+50 DEX, high ATK godlike item weapon. This is a powerful War of Emperium reward.)
• Twin Edge of Naght Sieger [3] (Fairly high ATK for a one handed sword, and has 3 card slots for Archer Skeleton cards.)
• Hurricane Fury [1] (Extremely high ATK weapon)
• Giant Axe [1] (Those who cannot afford the above weapons can settle for the Giant Axe. It has a very high attack power.}}

Headgear Choices:

• Abysmal Knight Helm [1] (Slotted and adds protection versus boss monsters.)
• Evil Marching Hat [1] (Slotted and adds noticeable damage to Acid Bomb.)

Garment Choices:

• Heroic Backpack [1] (Can add ranged damage, MATK, and ATK. This is the best garment)
• Nidhoggur's Shadow Garb [1] (A very defensive garment which will serve you well)
• WoE Manteau [1] (Best garment to use in WoE by leaps and bounds.)

Footwear Choices:

• Variant Shoes (Max HP/SP +20% if you leave these at +0.)
• Diabolus Boots [1] (Suitable increase to max HP.)
• Sleipnir (+25 INT and +20% HP/SP. This is a powerful War of Emperium reward.)
• WoE Greaves [1] (Best footwear to use in WoE by leaps and bounds.)

Armor Choices:

• Valkyrian Armor [1] (+1 STR/AGI/VIT/INT/DEX/LUK, slotted armor).
• Diabolus Robe [1] (offers some delay reduction for the after-cast delay on Acid Bomb)
• Diabolus Armor [1] (Good DEF, STR +2, HP +150. handy if you can't afford any of the above gears.)
• Bakonawa Scale Armor (Could be useful, as it reduces damage from boss (MVP) monsters. no card slot limits its use.)
• WoE Plate [1] (Best armor to use in WoE by leaps and bounds.)

Shield Choices:

• Valkyrja's Shield [1] (This is the best shield for MVPing/WoE by far.)
• Immune Shield [1] (Can be useful in MVP/WoE due to the neutral reduction.)
• Alice Card (Definitely a must-have for MVPing.)

Other:

• Black Devil's Mask (One of the best mid gears, all stats +2)
• Bradium Earring [1] (A good slotted accessory for boosting MATK)
• Bradium Ring [1] (Conversely to the earring, this one increases physical damage)
• Brisingamen (+6 STR/AGI/VIT, +10 LUK/INT, godlike item accessory. This is a powerful War of Emperium reward)
