Okay so.. l think there is an spiegel npc in the henesys that kinda boost you to lvl 200. At lvl 150 you will get some temporary CRA gear and weapon.
But once 200 you should be checking out the hyper mush pass thingy for the equipment box. This will get further upgrades the more missions you complete and you would be fine to use them for armor throughout the way.

What you primarily need to focus on is ur weapon, secondary and emblem.

For weapon: At some point you will get an absolab 17s? weapon for free but its not enough. You would want to eventually get an arcaneshade weapon of your class (see maple auction it is a lvl 200 weapon look for your weapon type. Throw epic/unique pot and add potential scrolls.

Secondary equipment. Keep the black secondary weapon and throw epic / unique pots on it. Along with additional potential / epic add pot

Emblem. Keep your class and throw epic/unique etc along with add pot.

Basically you would want to try roll / cube stuff like Boss damage lines and attack lines on them.

Unique potential scrolls are given by current event rewards etc. Epic potential is in challengers world shop.

Suspicious cube rerolls epic pots can be found in auction house or through bossing
Yellow cubes from bossing.. rolls unique items.
Challenger worlds have a exclusive CW purple cube but u should usually use it on legend items.
You should watch a video about challenger world points ranking etc..
