l2net:
here is official download (is free bot, dont need cr4ck etc.):
http://insane-gamers.com/latest/L2NET-WebInstall.exe
Instal it, during instalation select all packages (data pack, map pack etc.). Download could tak some time cause map pack = ~150 MB ;D
L2net requires also .net framework package (instalator will show notification if u dont have), so google, download and install it (from microsoft site f/e)
When u run l2.net go to File->Logon window, select Chronicle CT1.5, click "IG", paste DN server ip (85.14.217.252). You should see server list (infinity is second on this list). Login, select char, and go to File->Game Window. For me this guide is working - i see map, all skills, can use chat etc., so prolly i can also farm bot with l2net, i just dont know how to set it :)
