Homunculus AI
Your homunculus does not take orders from the server. Its behaviour comes from a script that runs in your own client, and DewataRO ships a good one by default: AzzyAI.
You do not have to install or configure anything. It is already on.
What it actually does
The stock Ragnarok homunculus AI never casts a skill on its own. It walks, it follows, it swings — and that is all. Every skill has to be triggered by you, by hand, one at a time.
AzzyAI reads your homunculus type and fights with it properly:
- Picks the right attack skill for what you are, and keeps using it
- Chases and disengages sensibly instead of standing in place
- Reacts to trouble — it watches HP and SP and backs off when things go badly
- Eleanor switches stance mid-fight, flipping between Sonic Claw and Tinder Breaker as the combo window allows
Which homunculi get skill support
Full skill routines exist for the Homunculus S line and Lif:
| Homunculus | Main attack skill |
|---|---|
| Eleanor | Sonic Claw · Tinder Breaker |
| Eira | Eraser Cutter |
| Bayeri | Steel Horn |
| Sera | Needle of Paralyze |
| Dieter | Lava Slide |
The classic line — Filir, Vanilmirth, Amistr, Lif — is covered by our own lighter routine instead. Filir casts Moonlight and Vanilmirth casts Caprice on their own. Amistr and Lif never auto-cast because they have no attack skill at all; they are the tank and the support of the family, and that is working as intended.
Turning it off
Type this in chat:
/hoai
That switches your homunculus to the plain stock AI. Type it again to come back. The setting lasts for your session.
There is very little reason to switch, but the option is there.
Summoning, resting and "my homunculus vanished"
The single most common homunculus report is "it disappeared and I cannot bring it back". Almost every time nothing is lost. The two skills involved refuse silently when they are given the wrong item, so it looks broken.
| Situation | What to use | What it consumes |
|---|---|---|
| You never had one | Call Homunculus | 1x Embryo |
| You put it away with Rest (Vaporize), or it went away when you logged out | Call Homunculus | 1x Seed of Life |
| It died (HP 0) | Resurrect Homunculus | nothing |
The trap is the second row. Recalling a rested homunculus needs a Seed of Life, not an Embryo, and Resurrect does nothing because nothing is dead. The Seed of Life is sold by exactly one NPC, the Material Seller in the Alchemist Guild, Al De Baran (alde_alche 38,184), for 60,000 Zeny. It is not in the Job Supplier and no monster drops it, so buy a few before you head out.
Handy controls:
- Alt+R opens the homunculus window (stats, skill points, intimacy, feeding).
- Alt+T toggles Assist / Aggressive.
- Right-click your homunculus for View Status, Feed and the same Assist toggle.
- Rest in the homunculus window puts it away; remember the Seed of Life to call it back.
If your homunculus is not using skills
Three things to check, in this order. All three are far more common than an actual fault.
1. Has it learned the skill? A homunculus earns one skill point every three levels, and points are not spent automatically. Open the homunculus window and put them in. A homunculus that never spent a point has no skills to cast, and the AI cannot invent them.
2. Is it a Homunculus S that just mutated? Mutation changes the class but the skill tree changes with it. The skills from the old form are still listed, and the new ones need fresh points.
3. Does it have SP? Skills cost SP, and a low-level homunculus has very little of it. If it casts once and then goes quiet, it is out of SP, not broken. This is normal below level 99 and stops being a problem as it grows.
Eleanor also builds spheres before her skills become available, so a few plain attacks at the start of a fight are expected.
Notes on our setup
We changed two things from AzzyAI's defaults after testing:
- Idle walking is off. By default the homunculus wanders up to 14 cells whenever it has nothing to do, which looks restless in town. It now stays with you.
- Blazing and Furious is disabled. The skill is unfinished in AzzyAI and fires with no cost check, draining a full SP bar in seconds and leaving the homunculus unable to cast anything at all.
Intimacy shortcut. The Homunculus Nutritional Supplement (item 100371) gives +20 intimacy per use on DewataRO instead of the official +1, so 50 tablets take a fresh homunculus from 0 to Loyal (1,000). Intimacy still caps at 1,000.
Mercenaries still use the stock AI. AzzyAI's mercenary half is installed but not enabled yet.
