Not sure if it is easier to "adjust" 2-4 of the starter area quests to give the xp, spirit and rep, or to "change" what the character starts with. But here is my idea to quickly get you from starter city to arch. It also allows for the veno to take care of the couple of quests that are specific to the class, that give them their pet, pet tame, pet heal and pet revive.
Do the starter quest (the 2 from your start npc, that have you kill like 10 of each starter mob)
go to the elder in the starter city, get the "meet and greet" quest (where you go and get the gear)
when returning to the elder to complete the quest, change the Exp, spirit, rep and coins received -- completing this quest will take you to lvl 9
using highest numbers from all classes, would be: Experience: 11,410 spirit 2800 reputation: 18 coins: 6700 (sp, coin. rep is all 1x)
this will take the char to lvl 9 -- after maybe 3 minutes of play
after talking to elder, reaching lvl 9, go talk to taoist for the city -- A Little Progress i think the quest is (no change to quest reward)
**veno can do the quests for pet books/ pet at this point
take the next quest from taoist -- go talk to the "recluse" for the race -- kill the 9 mobs, return to npc, finish "culti" (no change to quest reward)
you then go back and talk to the taoist again -- reward is increased to take player to lvl 19
do the 19 culti quest chain (kill mob for 1 sprite, dig the other) (no change to quest reward)
talk to elder, receive tabs for 19, and either teleport to or opening of tele point to arch (increase the exp for the quest to make the player lvl 20) (exp of 22,325)
You have now completed culti and leveled to lvl 20 in about 20 minutes (or less depending on how quick you are) and are in arch
My only concern, is you are in arch with inadequate gear to kill anything outside the gates, so perhaps a NPC in arch you talk to to get a "new" set of starter gear? Or change the gear received from the NPC's (meet and greet quest) to be useful when you reach arch and lvl 20
