Hello guys I’m new here, also I’m new on those things I  don’t know anything about programming but I need some help about many things …I want to open a faction server 

Firstly , I want to make a classic but with interlude staff like skills items level etc ..so

is there any project server interlude -classic ..is there any interlude -classic client ? 
what other server doing ? 
can I go with interlude and add a patch-interface that will work for all people whos gonna join the server,  that will have inventory stats bars etc from classic , lobby create character ..etc and L2Fonts  for title and names also chat letters  like classic ? 

I read about Lucera 2 has an interlude -classic client is it correct ? I also read about a multi protocol ..

 

also I saw that there is a lot of classic chronicles like 2.0 2.5 2.6 2.7 2.9.5 3.0 

what are the differences 

 

I know that the 3.0 add kamael which I don’t want

Your options are ,

1. pay for files like lucera
2. pay for a dev to create what u need
3. learn how to code and u do it urself
4. find the old discontinued interlude classic source from mobius and work with that. 
5. there are some heavily modded interlude files on other forums that offer what u asking ( interface , classic/essence style etc)

First, you need to understand what you're doing and what you want to achieve. You have to choose a server core. After that, decide what you want your server to include, code it, modify the client to fit your server, go public, and drink champagne.
 

If you know how to code, creating a server is relatively easy — a few months of work and you can make it happen. Modifying the client is a completely different story. There’s a lack of tutorials, tools, and source materials. I’m currently working on the client myself, and I’ve already spent over three weeks just trying to get started due to the lack of information.

If you don’t have the knowledge and experience, you’ll need a team and a bag of money — but realistically, it just won’t succeed.

Hey there, welcome to the community – no worries about being new, we all started exactly where you are. Let me break this down based on what you’re trying to achieve with your Interlude‑Classic idea.

 

What you’re describing is actually a pretty popular concept: basically Interlude gameplay and balance, but with Classic‑style UI and a cleaner overall user experience. A “hybrid client”, not a full chronicle change.

 

Projects that have done something similar or are worth studying:

 

Lucera 2 – You’re right about this one. They use a custom client that blends Interlude gameplay with a more modern/Classic‑like interface. Their UI work (inventory, skill bar, lobby, etc.) is a good reference point.

 

L2J Mobius – Not exactly your target, but it’s very flexible and has a lot of examples of customizations and adaptations between chronicles.

 

Smaller custom projects – There are (or were) a few hybrid attempts using Interlude server files with heavily modified clients, but most are private or closed‑source, so you mainly get ideas, not ready‑to-use files.

 

Where the real challenge is (the client side):

 

What you want is possible, but the heavy lifting is on the client, not the server. The main pain points usually are:

 

Making sure interface files are compatible between chronicles (UI textures, layouts, systemmsg, etc.).

 

L2Font and localization edits: titles, chat, system messages – a small mistake here can break visuals or cause weird text issues.

 

Character selection / lobby screens: if you take them from another chronicle, you have to adapt them carefully so they don’t conflict with Interlude data.

 

Inventory, status bars and shortcuts: they must still work with Interlude’s item/skill structure and packet format, or you’ll get visual desyncs and client errors.

 

About multi‑protocol:

 

You’re correct that multi‑protocol is often used by projects that want to support different client versions or custom blends. In your case, it can help “talk” properly with a customized client while keeping an Interlude base server. It doesn’t magically fix everything, but it gives you more flexibility on how client and server exchange data.

 

Quick chronicle breakdown (relevant for your idea):

 

2.0–2.6: Early, simpler mechanics, good base for old‑school vibes.

 

2.7: More skills and better balance, often used as a base for custom projects.

 

2.9.5: A “bridge” between old and new, very common choice for hybrid or heavily modded setups.

 

3.0+: Adds Kamael and systems you said you don’t want, so you’d mainly use it as a reference, not as a direct base.

 

My honest recommendation:

 

Start from a solid Interlude base (files you understand and can actually maintain). Interlude still has the most support, tools and community knowledge.

 

Focus first on UI/interface modifications instead of trying to change core mechanics. Use Lucera‑style clients and similar projects as visual/technical reference.

 

Consider a multi‑protocol setup only after you’re comfortable with a normal Interlude client; otherwise you’ll just stack complexity.

 

Join active L2J / client‑mod Discords and forums. There are specific channels for interface, system edits and client reverse‑engineering where people share tips and tools.

 

What I would avoid at the beginning:

 

No intentar mezclar tres o cuatro chronicles a la vez; con uno bien entendido + UI custom ya tienes más que suficiente trabajo.

 

No subestimar la parte de cliente; muchas veces es más complicada y más frágil que el lado del servidor.

 

No saltarte el testeo en entorno local; los híbridos rompen cosas pequeñas (tooltips raros, skills que crashean el cliente, UI bugueada) si no pruebas bien.

 

Resources worth checking:

 

L2J forums and old MaxCheaters threads about faction/hybrid servers and client mods.

 

GitHub repos with client tools and interface mods (even si no son exactamente tu chronicle, te sirven como ejemplo).

 

Discord communities focused on L2 client development; ahí es donde se mueve hoy la parte “seria” del modding.

 

The good news: what you want is achievable, just not “plug & play”. It will require patience, testing and a bit of learning on both server and client sides. If you share exactly which files/pack you’re planning to use and what you want your UI to look like, people here (me included) can give you more concrete, step‑by‑step advice.
