12142.gifi. Introduction

In this guide, I'll be covering the basics of a Biochemist - what a Biochemist does and uses.

Do not expect 'godly' results from this guide, for I made this to help people who are clueless about Biochemists.

Biochemists is a.k.a. Creators, BUT Biochemist sounds way cooler.

But why a Biochemist?

  1. Acid Demonstration's damage is reliant on enemy's VIT, therefore you'd do high damage since VIT is needed in abundance for HP.
  2. Acid Demonstration is spammable, fast enough to filch your opponent.
  3. Acid Demonstration has 10% chance to break Armor and Weapon.
  4. Full Chemical Protection prevents equipment breakage.
  5. Ability to manipulate a Homunculus.



7760.gifii. Getting Started

Before you become a Biochemist, here's a few facts-for-dummies:

  1. Acid Demonstration relies on YOUR int, as well as the ENEMY's VIT for damage. Therefore, the higher your INT and your opponent's VIT, the higher the damage. STR does not affect the damage.
  2. MATK-boosting gears does not increase the damage of Acid Demonstration. Acid Demonstration is dependent on your INT, not your MATK.
  3. Acid Demonstration is always Neutral element, meaning the damage can be reduced by Ghostring, Raydric and Deviling cards.

Acid bottles, Bottle Grenades, Glistening coats and other Biochemist's items can NO LONGER be bought from the Mall's Tool Dealer. Hence you have to create them manually.

Detailed information regarding how-to-create and the ingredients for the items can be found at:

1553.gifvi. Stats Allocation


* +1 base damage per point for melee weapons.

* A bonus of (Str/10)^2 total (ie, at 50 Str, 25 points total) for melee weapons where Str/10 is rounded down.

* +1 base damage per 5 points for missile weapons.

* +30 carrying capacity per point of Base Str.


* +1 flee per point.

* Increased attack speed per point (complicated, but based on the atk speed of the weapon you are using in the class you are in).


* +1% to MaxHP per point.

* +0.8% weapon damage reduction (defensive) per point.

* Healing items effect increased by +2% per point.

* Every 5 full points of VIT increases HP Recovery Power by 1.

* For monsters, there is a bonus to damage reduction of rnd(0,[VIT/20]^2-1).

* For players, there is a bonus to damage reduction of [VIT*0.5] + rnd([VIT*0.3], max([VIT*0.3],[VIT^2/150]-1)).

* There is a hidden bonus of +1 Int style MDEF per 2 points.

* Increasing VIT also decreases the chance of being afflicted by the negative status affects of Poison, Silence and Stun.


* +1 Base MAtk per point.

* +1% to MaxSP per point.

* SP Recovery items effect increased by +2% per point.

* Every 6 full points of INT increases SP Recovery Power by 1 and past 120 INT, every 2 INT gives a bonus to SP Recovery Power of 1.

* A bonus to MinMAtk of (Int/7)^2 total where (Int/7) is rounded down.

* A bonus to MaxMatk of (Int/5)^2 total where (Int/5) is rounded down.

* +1 spell damage reduction (defensive) per point.

* Increasing INT also decreases the chance of being afflicted by the negative status affects of Blind, Sleep and Stone Curse.

* Reduces spell casting time by a percentage calculated as Dex/1.5 (ie. 30 Dex = 20% casting time reduction).

* +0.1% forging and refining rates for Blacksmiths.


* +1 base damage per 5 points of Luk for missile and melee weapons.

* +1 crit chance per 3 points of Luk.

* +1 "lucky" dodge chance per 10 points of Luk.

* +0.1% forging and refining rates for Blacksmiths per point.

Rough gauge:

STR: 100 (to carry items without being overweight)

AGI: 100 (for ASPD and flee in Player versus Monster)

VIT: In multiples of 15 for extra HP boost

INT: 200 (maxed)

DEX: <150

LUK: Luck is obsolete for Biochemists. However, if you want to contribute points into LUK, Lucky Dodge comes in multiples of 10
