I've been getting a lot of visits because of this post. Please leave me a comment or 2 if this worked for you or not - that's all I'm asking.
If you've read my posts before, then, you know that I'm a Ragnarok Online addict. And, just a few months ago, we found out that it's way easier to level up using the Mercenary system. Oh, we're from Valkyrie server in pRO, by the way.
If you're not familiar yet with the Mercenary system in Ragnarok Online, I would really suggest you read this informational page from iRO. Basically, a Mercenary attacks for you so you won't have to. They're especially a big help to Acolyte and Mage classes.
When we first used a Mercenary, we thought it'll auto-attack immediately. When we found out it doesn't, we figured that the only ones that auto-attack are the higher grade Mercenaries. Yes, we didn't know yet about the AI so they can auto-attack. I've already figured out how to get it working the way I wanted to and I want to share it with others who don't know how to do it. And, yes, just recently, I found out that there are indeed some players who are still unfamiliar on how to get the Mercenary to auto-attack. And I've searched everywhere and nothing was specifically written on how to get them working. So, for the lazy ones, here yah go.
First of all, you have to know the basic controls of a Mercenary. To move them around, you have to press ALT then left-click on where you want them to go. If you want them to MANUALLY attack a monster, press ALT again and double-click on a monster. If you're like us who constantly run from summoned monsters in Moscovia, then, you'll be very used to controlling your character and your mercenary at the same time (almost). Hehehe.
Another thing. I believe that a lot of people enjoy summoning monsters at Mercenary-invaded areas because it's like using a non-3rd party bot in Ragnarok. So, if you haven't tried it yet, here's your chance. If you're from Valkyrie in pRO, I suggest go to Moscovia with a BOW Mercenary.
There are other types of Mercenaries - Spear, Bow and Sword. My favorite is the Bow Mercenary. This AI, though, works for all Mercenaries but I revised it especially for Moscovia tambays.
You need the AI files for your Mercenary to use its skills and to auto-attack. The one we're using is ZenAI.
I've already modified the Config_M.lua file so your Mercenary is ready to auto-attack. Download the revised ZenAI from here. (Updated link)
Updated: (5/21/2009) My mercenary AI was working great but my Alchemist's homunculus AI was messed up. So, if you're planning on having a mercenary and a homunculus, download my ZenAI revised edition II. (UPDATED LINK as of January 7, 2012)
Note: This was revised for use at Moscovia with a Bow Mercenary. The only skill that will work with a Bow Mercenary is Double Strafe because the rest are just waste of SP. I disabled other skills only for the Bow Mercenary. Anyway, you can manually use other skills such as Skid Trap and Magnificat.
You can read more information about ZenAI from here.
After downloading, unzip (using Winzip or Winrar) all the contents of the file (.lua files) to your Ragnarok Online USER_AI folder.
For example, if your Ragnarok client is installed in your Program Files, then, the folder should be:
C:\Program Files\Gravity\Ragnarok Online\AI\USER_AI
If it's not in Program Files, just search for the USER_AI folder. All files should go there. If it prompts you to overwrite, just press Okay or Yes.
After the files have been extracted, go login to Ragnarok. Type /merai (as in Mercenary AI) in-game. You should get a mesage saying that the Mercenary will use a custom AI or basic AI. Well, it doesn't really matter because we've already configured the AI.
Your Mercenary should auto-attack already. If it doesn't, I suggest you re-login and try it again. If it still doesn't, make it move away from you and when it goes back close to you, it should start auto-attacking all those monsters and you can just watch yourself levelling up like crazy (well, if you're at low levels hehehe).
Make sure you bring Mercenary Red and Blue Potions with you 'coz they'll be aggressive. If you want them to temporarily stop auto-attacking, just right-click on the Mercenary and select Standby.
In case you mistakenly placed the files in the WRONG FOLDER, here's my original AI files for you to copy. Download it here.
That's it! It's as simple as that. If it doesn't work for you, leave me a message or 2 and I'll get back to you as soon as I can.
