1: Teleport Service made easy.
Create (or use an existing) character of the WHM job and level them the the highest desireable level for which teleport spells you want. Which should be fairly easy and cheap as everyone wants a WHM reagardless of gear. Do NOT get the teleport crystals for them, but get the scrolls. Now everytime that character casts Teleport-**** they will remain in place.
2: Strange Apparatus use.
Strange Apparatuses located across Vana d'iel can provide you with decent amounts of gil for relatively little time. When wishing to operate one, bring with you one Infinity Core (dropped in Dynamis
or found on the Misc. section of the AH) and one colored Chip bought from Golbins in the three main cities(make sure the chips color corresponds to the color of the light on the machine you wish to use). When approaching the machine, input a numeric password generated
http://sholin.user.tehh4x.net/password/password.php here. Trade your colored chip and infinity core to the machine and sit back. Repeat if you so choose. (*note* you don't actually NEED to go into Dynamis or know anything about it to use these. Details on locations and chip correlation can be posted. Tried and tested process, but a gamble.)
3: Removing monsters from the game.
If you're ever camping a mob or NM and constantly target another creature on the pc, there's a way to stop that. Open up the model viewer (found
http://www.folye.net/ here) and turn on the option to view .dat numbers. Locate the mob file you wish to remove and simply.. remove that file (to your desktop or a backup folder is best). Now when you re-enter the game you will notice that mob is gone. Be warned, they can still attack you!
4: Norg Quest Mule.
Start a mule in Bastok and run them to Jeuno. Get them access into the Tenshudo and death warp back to Bastok. Build your fame there by buying and trading in Zinc (should cost >100k). With a friend or second character, run to each city and collect the tele crystal and key for Kazham access. From there, go to Norg and begin the quests. The rest is self explainatory. This is a guaranteed 500k+ for completing Utsusemi, Tonko, Hojo and Jubaku Ichi (1.1m total on my server.)
