You can make an "invisible npc" by using a dummy npc (without mesh) from the client. The code will be executed on creation or on a timer, there is no need to talk to the npc.

Riding the wyvern is done through AI. Copy janitor.nasc for example, create your own npc, remove checks and utilize RideWyvern function. If you want to do it via an item, a cool way is to make the item summon an invisible npc, and then that npc, on creation or on a timer, executes the code I described above on its summoner. They should work, but I haven't tried any of these.

From myext64.ini : ; Multisell filtering - if true, allows only multisells mentioned in last HTML sent to user ; in format action="bypass -h menu_select?ask=-303?reply=#" where # is multisell ID ; TO MAKE IT FULLY WORKING, YOU NEED SOME CHANGES IN HTML - OTHERWISE SOME MULTISELLS WON'T WORK! ; If you need to allow multisell that's not in format parsed by the filter, you can use this hack (example): ; <A action="bypass menu_select?ask=23000&reply=655" altaction="bypass -h menu_select?ask=-303&reply=655">Buy special products.</A><BR> ; If you need

It's easy and quite elegant (no need for extra system files) to do it:

Check here https://sites.google.com/site/l2clientdev/system-m0nster-io I personally never managed to launch game under 83 protocol (splash screen doesn't even show, although L2.exe is visible in task manager), I simply switched to 87 protocol thanks to Emca's extender.

Thread is pointless by trying to discredit one of the few honest admins left. Good luck with your project @Trance as we finally get the chance to enjoy a decent L2Gold server.

I find the idea of creating a site that promotes serious servers very interesting. Quite frankly I would probably cut out like 95% of the servers that launch. A few criteria that would make a server approvable or not could be: Features. Is there anything new and unique? L2OFF or L2J? Bringing something new to the table on L2OFF platform should be encouraged for obvious reasons. On the other hand, an L2J server that has nothing unique at all is probably inexcusable. *(Depending on rates ofc) How much time did the server require to get prepared? Were things tested

Create 9 new items (with the icons you want) that unpack into the desired amount of AA.

Hey, here's a couple of effects that could be useful. For example, whenever you learn a skill or acquire a certain status. https://mega.nz/file/aZlUDSpK#p544f7fQi-qG0yeg2KSIJo3kZoESpuQUCJ9EsChP-Qo

What you want to modify is indeed done through AI, try this tool For quest rewards you should have a look at MY_DYING handler inside the decompiled class of the mob you're interested in.

You probably messed it up in the client (skillgrp). Example: 3 1 0 10 40 3 1.08000004 0 S icon.skill0003 0 0 0 0 9 11 The yellow number must be 0, not 1.

What if the NPC casts a target cancelling debuff, simirarly to Trick/Switch?

The relation is done by server scripts, not client. Assuming you use l2off (judging from your post history): Client shows the passive skill acquired only when the server is live, in passive skills tab (so long as the passive is added in the appropriate .dat files).
