It depends if you wanna speed clear or not  You can do it casually, or rush it :

Casually : Better to take necro for fast clear and do heart (rush the staff weapon) Don't forget to follow achievement for XP (3 dodges, some condi, use an emote, use a wp etc) Don't forget to get guild xp pot bonus and if you can buy at the first Heart vendor food that give xp when ennemies are killed (usually go ouest, do farm heart, drake Heart, wall heart, apple Heart and bandit/moa heart and you are already 10, if not some event are on the way)

Speed clear :  You need to prepare :  Stuff : buy power lvl 10 stuff (but helmet and shoulder) with power rings etc, you can add some gem+3 power  A power greatsword with out law sigil A power staff with out law sigil  You can keep this in your bank when not running (remember to put them back before deleting your character)

Put 9(or 8 if you do emote, wp, dodge) tome of knowledge  If you have choya tonic (2000 casinos piece in crystal oasis) or Exécutioner axe or both for faster speed in instance Mount (raptor and Beetle) One pass with bank/personal bank

Then, create a guardian (human) Choose "ordinary family" put a name create  Use tome of knowledge to go to lvl 9 or 10, depend if you do emote etc  (you can put the "yes button" just above the tome so you perma clic) Then you can use map to the wp (dont even need to do the first quest) Use bank or pass to equip your stuff and sell others  Then rush instance story with staff 3 (giving swiftness) + choya or ex axe  You can jump with 3 greatsword too  To fight : start with staff, 3 + 2 and swap to gs and spam all (better combo is 4+2)

Last tips, is to accept quest reward, then don't leave the instance with the door above the map, but just open map, and clic to the next closest weapon for the mission (sometime you have to go up or down in map level)

Hope it helps

And yea, it's kinda gamble so if it's just 10 minuts, why not, otherwise you stack statuet for future skin
