RCX just gives you more info Buff timers, Exp gained, Monster info, recording replay purposes, max range and etc... not much help about lags
been using this since i was playing official servers was really helpful
1. You can add custom mobs and skills but not jobs since this will need to replace old jobs.
2. Items as many as you want.
2.2 Mobs ID are from 1000 to 3999 (should be put before JT_MONSTER_LAST and be sure to adjust the ID too)
2.3 Skills i don't think the limit is still known but it should be enough to have all your custom skills.
2.4 depends on how many you want old job ids to be sacrificed just to apply your custom job.
you didnt seem to get my point.
even if you are able to make an @command that and restrict it to other players, they can still use /web instead.
This is clientside unless you disable it in the client by hexing the /web which is also make your @command gets buggy/unusuable.
