Homunculus System
The Homunculus is a special pet which assist Alchemist classes in ways such as a support, an instant partymate, or a sacrifice for the player. Alchemist classes must go through theBioethics Quest to unlock the appropriate skills required to create a Homunculus. After the quest, the skill Bioethics will be available to the player and the rest of the Homunculus skill branch will be available through the distribution of skill points.

Obtaining a Homunculus
To obtain a Homunculus, an Embryo is required. These can be purchased from other Alchemists or can be self-made. In order to make an Embryo, an Alchemist must use the skillPrepare Potion with the following materials purchasable from the Al de Baran Alchemist guild (alde_alche 35, 179):
- Dew of Yggdrasil
- Seed of Life
- Glass Tube
- Medicine Bowl
- Potion Creation Guide (not consumed)
Once an Embryo is obtained, use the skill Call Homunculus to summon the Homunculus. There is a chance to get 1 of the 4 homunculus and another chance to get 1 of the 2 sprites available to each type of homunculus. Although not completely proven, it is a popular "fact" that the creator of the embryo's stats plays in a role in the probability of summoning each Homunculus.
Homunculus Status and Skill Points
Homunculus have their own set of stats apart from their masters, these will have a set amount upon summoning and will vary as it levels up. With each level, a Homunculus will receive a certain amount points to each stat (STR, INT, DEX, AGI, VIT, LUK) depending on which type of Homunculus. These stats are invisible under the Homunculus stat window (Alt+R). The Homunculus's ATK, MATK, HIT, CRITICAL, DEF, MDEF, FLEE, and ASPD will be visible. To calculate the Homunculus's stats, use the following equations. The Homunculus also gains one skill point for every three levels. Unlike status points, one can apply these to whichever skill one would like.
Pre-renewal Calculations
Note that these are pre-renewal, and thus false.
ATK
- Min ATK = STR + [STR(Rounded down to the nearest multiple of 10) / 10]2 + Dex
- Max ATK = STR + [STR(Rounded down to the nearest multiple of 10) / 10]2 + Max(STR + Level, DEX)
MATK = INT + [INT(Rounded down to nearest multiple of 5)/5]2
HIT = Level + DEX
CRIT = [LUK/3] + 1
DEF
- Armor Def = [Level / 10] + [VIT / 5]
- VIT Def = VIT - 1
MDEF = [Level / 10] + [INT / 5]
FLEE = Level + AGI
ASPD = 200 - (Delay/10) + ( [4*Delay*AGI/1000] + [Delay*DEX/1000] ) / 10
Special note for Vanilmirth owners: Due to Instruction Change having an unfixed bug since 2007, the STR and INT bonus from Instruction Change will be lost when one re-summons their homunculus, changes maps or relogs.
Renewal Calculations
- ATK = Floor((STR + DEX + LUK) / 3) + Floor(Base Level / 10)
- MATK = Base Level + INT + Floor((INT + DEX + LUK) / 3) + Floor(Base Level / 10) * 2
- HIT = Base Level + DEX + 150
- CRI = Floor(LUK / 3) + 1
- DEF = (VIT + Floor(Base Level / 10)) * 2 + Floor((AGI + Floor(Base Level / 10)) / 2) + Floor(Base Level / 2)
- FLEE = Base Level + AGI + Floor(Base Level / 10)
Evolution
Use a Stone of Sage (simply double click it) when the Homunculus's intimacy is Loyal to evolve it. With evolution, the Homunculus will obtain a random bonus of 1-10 for each of the stats, increased HP and SP, and a new sprite.
After evolving, the Homunculus' intimacy resets to 10 (Hate). Once its intimacy reaches 910 (1 point before Loyal intimacy) again, a fourth, new skill is unlocked.
Controlling the Homunculus
Manual Functions
Here is a listing of all manual functions with the default AI. In general, there will be no need for any other manual functions in most Custom AIs
- Alt + Single Right Click: Target monster
- Alt + Double Right Click: Attack monster
- Alt + T: Standby, idle/passive mode, cancels all commands and returns to master
- Alt + Right Click Ground: Move to location (15 tile range)
- Alt + R: Information window
If the player is dead, manual commands can't be issued. The AI will continue to function as normal however.
AI
AI is the brain behind the Homunculus. All Homunculus behavior is controlled by an AI script. There is a choice between the use of the default script or a custom-made script. The Default Script is both poorly made and simple. The primary problems with the default script are that the Homunculus will either kill steal everything (default AI'ed Vanilmirth and Filir) or will not attack anything at all (default AI'ed Amistr and Lif). Hence it is recommended to make a custom AI or use a premade one made by users. To switch between the Default AI and the User AI, use the /hoai command.
Installing AI
Once AI script is downloaded, go to the default RO directory. This is generally located at C:\Program Files\Gravity\Ragnarok Online\AI. Insert the downloaded AI Script into the USER_AI folder and relog or resummon the Homunculus. This should be done every time there is a change in script. While there are infinite possibilities with AI scripts, it is necessary to understand that there are things it can and cannot do. These limitations are what separates it from bots.
Possibilities
- Automatically attacking monsters within player's sight range
- Auto Casting Homunculus Skills, including ground skills
- Different tactics for individual monsters (ex: what priority to attack, using a skill on that monster etc)
- Reading the HP, SP, MAXHP and MAXSP values of the Homunculus or its owner
- Reading the target of a attacking monster (to avoid kill stealing)
- Reading the current animation or "motion" other actors are doing. (this is buggy when used on homun itself.
- Automatically shut down the Ragnarok Online client using
os.exit()
- If owner's alchemist is being attacked, it logs out after 5 seconds after calling os.exit()
- Otherwise, if the alchemist is not attacking or being attacked, that character will log out immediately after os.exit() is called.
- This may not work on Windows 7 and later, instead producing an error message and hanging the client, but not logging the user out until they click through the error or the server times out the connection.
Impossibilities
- Detecting whether other players are in a party with the owner.
- Detecting who the owner of another homunculus is (GetV(V_OWNER,id) returns your ID, regardless of what the second argument is).
- Detecting status effects or ground effects
- Identifying skills used, or gathering any other information not listed above.
- Locating hidden players.
- Auto Feeding
- Auto Looting
- Using skills while their owner is Vending
- Homunculus maintain its AI when out of range of the Alchemist
- Having the Alchemist move around. (Except when auto casting the Castling Skill)
- Reading the HP, SP, MAXHP and MAXSP values of someone other than the Homunculus or its owner
- Auto-casting any player skills (Disabled after 5-Feb-2008)
Not Allowed
- Using a 3rd party program.
- Reading in real time the output of the Homunculus traceai, so that one gains a read out on what is around the player (including things that the game client won`t show). According to a GM post on the iRO Forums "Doing this when monster leveling would not be such a big deal but in PVP/WoE purposes it is a very unfair/unintended thing. Users violating that rule will be suspended."
- Feeding the Homunculus or moving the owner around using a 3rd party program.
- Players are responsible for the actions of their Homunculus. For example, if the Homunculus kill-steals people, then the player is held accountable and may be punished accordingly.
Feeding and Intimacy
Much like pets, Homunculus require feeding. Feed the Homunculus when its hunger is between 11~25 to get 1 full point of intimacy. Feeding at the other times will give less than a full point and may even reduce the intimacy. If one forgets to feed the Homunculus, its intimacy will decrease, and it will leave the master if it goes below zero intimacy.
| Hunger | Intimacy |
|---|---|
| Starving at 1%~10% | -1 (every 200 seconds) |
| 1%~10% | 0.5 |
| 11%~25% | 1 |
| 26%~75% | 0.75 |
| 76%~90% | -0.05 |
| 91%~100% | -0.5 |
The homunculus also display emotes as a way of warning the player. The emotes used are:
| Status | Emote |
|---|---|
| Hunger below 11% every 20 seconds | /sob |
| Player feeds without proper item | /swt |
| Player feeds at 1%~75% | /ho |
| Player feeds at 76%~90% | /swt2 |
| Player feeds at 91%~100% | /wah |
| Failed to use skill | /... |
| Failed to evolve | /hmm |
Intimacy is crucial for evolution, obtaining the final skill, and AFKing. Intimacy has not been proven to affect Homunculus stat growth. Intimacy points will not show in the Homunculus window. However for each interval of intimacy points the Homunculus has, the window will show:
| Intimacy | Status |
|---|---|
| 1-3 | Hate with Passion |
| 4-10 | Hate |
| 11-100 | Awkward |
| 101-250 | Shy |
| 251-750 | Neutral |
| 751-910 | Cordial |
| 911-1000 | Loyal |
Manipulating Intimacy
The player dying, the Homunculus dying, or the Homunculus vaporizing does not affect intimacy. Stressing it (other than using ultimate skills) is the only way that to lower its intimacy. One can stress the Homunculus by not feeding it (hunger < 11) or overfeeding it (hunger > 75).
Each hour of starving causes 18 Intimacy loss (3600 seconds per hour / 200 seconds per loss). If the player is away from the computer for a full 24 hours of starving, the Homunculus loses 432 Intimacy. If the player can no longer use Call Homunculus or Homunculus Resurrection, then the Homunculus has left its master for good. However, Alchemists are able to create a new Homunculus.
Experience & Leveling
General Information
- When a monster is killed by a homunculus alone:
- Owner gets full Base Experience, but no Job Experience, from the monster.
- Homunculus gets the full experience from the monster.
- If a player kills a monster and his/her homunculus doesn't contribute to the kill at all:
- Player gets all Job Experience from the monster.
- Homunculus get no Experience at all,
- If a monster is killed by having both the player and his/her homunculus dealing damage to the monster.
- Player gets 105% of the monster's Base Experience. For example, a Sidewinder gives 720 base experience. If both the player and the homunculus participate in the fight, the player gets 756 experience (720 * 1.05) instead.
- Player gets a portion of the monster's Job Experience based on how much damage is dealt by the player (the Job Experience pool is 105% of normal)
- Homunculus gets a portion of the monster's Base Experience based on how much damage is dealt by the homunculus.
- Whenever the player dies, if the homunculus is above 80% HP, it will automatically be Vaporized. If it's below 80%, it will not vaporize and is able to continue to fight, and the player continues to receive Experience from Homunculus, but manual commands cannot be used.
- It's a common mis-conception that when a homunculus defeats a monster, they get the Job Experience of the monster. In actuality, they get a copy of the Base Experience of the monster, modified by the damage they did to it and how many people attacked it.
- Experience gained by a homunculus owner from unassisted homunculus kills can be shared in a party.
