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)

Success rates of creating embryos are affected mainly by the Alchemist's DEX and LUK.

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

Pre-renewal Calculations

• 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)

• Armor Def = [Level / 10] + [VIT / 5]
• VIT Def = VIT - 1

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)

AI

Installing AI

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.

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.

Miscellanea

• They gain a skill point for every three levels. There is no job level equivalent.
• They obtain additional EXP from server rates, but NOT Battle Manuals.
• Their Flee and Defense is not reduced by the number of monsters.
• Their Hit is capped at 99%. Even if it has way more hit than required for a monster, it will always miss at a 1% chance.
• All Homunculus have a base attack speed of 1.4 seconds / attack (130). Different stat growths lead to different attack speeds of each Homunculus.
• Homunculus stat growth is RANDOM. However, nothing will affect which stats will grow and which stats will not.
• Homunculus can hit Ghost property monsters.
• It is possible to fail to create the embryo.
