I saw S grade weapons even in C1 private servers, maybe you didn't see them in game in low rates, C3 client came with S grade textures/meshes inside, in C1 we had to patch it, anyway in this server game is affected by skills not by p/matk.
Btw to get S retail grade items u need help from a spoil and a crafter, or raid drop boss

i have 3 question!:
1. Can i start this server on Interlude files?
2.if i cant start on c6 can i start on c5 files?
3.if i cant start on c5 can i start on c4 files?

The server only can be played with C3 client, i through you are thinking that its based in smeli's source, no thats wrong its C1 server extended to C3 with own ext.

A grade is the top equipment in c3, s grade came in c4. They added sa's in c3.

so there is no way to startthis server on any other chronicles?:(

Nope, you need a C3 game client.

it's ok but what i said is that c3 client has the files for show some s grade weapons like shinning bow or imperial staff or dragon thoot and that some private server were using it at the begging of c3 like l2extreme and others did.

So yes! the server has some customs that were'nt in c3 RETAIL but that were in almost all private servers, some customs like s grade gear, custom armors or dusk weapons or hero quest, things that from my point of view makes this 35x server more amuse and better that if it had been retail-like, retail-like servers doesn't adapt to the characteristics of a pvp server (ofc yes for a low rates).

And isn't easy to get this gear you have to craft it with dwarfs, kill raid bosses or gamble..

Our current solution which works nicely atm is using VMWare. We're trying to come up with another solution, we got C4 working on Windows 7, but C3 is just very outdated. Won't stop trying though
