>>328955351) Halu ASAP as mentioned, but be careful with overlevelling it too quickly, it's dangerous
2) Get History and Civilization (preferably high ranks) as quick as possible, as they both scale incredibly well with high Halu and you'll need the damage
3) Max Feathers so you have a decent weapon while you fend off the mobs
4) Get defensive items (Especially bandaid, full meal and nurse's horn) quick, because you WILL get hit with how many mobs spawn from every direction
5) Make a build with your favorite other items
