For the original Asheron's Call client
RynthCore and RynthSuite
RynthCore is a modding host for the original client (acclient.exe): its launcher starts the game, injects the RynthCore engine, and draws plugin windows in an in-game overlay. RynthSuite is the set of plugins that run on it, with RynthAi, the bot, at its centre. Written from scratch and MIT-licensed; nothing in it comes from VirindiTank or any other closed tool.

For the other plugins, extract the zip into C:\Games (RynthNav's navmesh is included), then add each plugin's DLL in the launcher's Plugins tab. From then on the launcher keeps everything up to date by itself.
Guides
How to use it
Step-by-step guides to the newer panels and features: what each one does, how to open it, the basics, tips and known limits.
- Sense — find monsters, players, NPCs and portals by name, far past the radar, and select them with a click.
- Meta Manager — switch metas on a timer: quest timers from
/myquests, minutes on a meta, repeating clocks and countdowns. - Inventory panel — RynthCore's own inventory window, Classic and Modern.
- Skills panel — raise skills, attributes and vitals with XP, train with credits, and see your buffs.
- Weapons and elements — how RynthAi picks the element and the wand, and how it swaps weapons.
- Click to select — select things by clicking Radar dots and monster nameplates.
What's in it
The plugins
- RynthAi — the bot: combat, buffing, navigation on VTank-format routes (
.nav), metas (.metand.af), loot profiles (.utl), salvage, mana stones and ammunition crafting, with a Loot Editor alongside./ra helplists its commands; the UtilityBelt (/ub) and Mag-Tools (/mt) commands that metas use work too. - RynthChat — a tabbed chat window, with the Rynth plugins' own lines kept on a tab of their own. Its Tell button starts a
/tellto whoever you have selected, and it can stand in for the retail chatbox or sit beside it. - RynthNav — walks the navmesh to wherever you point it, across landblocks and through portals.
- RynthTracker — your session: experience, luminance, kills and deaths.
- RynthVision — marks unclimbable slopes and impassable water in the world around you.
Updates
The launcher keeps itself up to date
From build 2026.9.26.3 on, the launcher checks for updates when it starts and every few hours, or when you press Check for updates on its Plugins tab. Plugin updates install in the background and take effect the next time you start the game, so a running bot is never interrupted. A RynthCore update (engine and launcher) asks first and installs once your game clients are closed.
Every update is signed, and the launcher refuses anything that isn't, so nothing can reach your client that didn't come from us. The version you're running shows under the title in the launcher, and in game when you hover RC on the overlay bar. If you installed a build from before 26 September, run the installer above over it once.
