Cafrisun Set is fine to use until you can switch to Roxona. Rokas Leather Armor can stay, no need to replace. Roxona Leather Pants isn’t worth it either so you can just use white gear for that.
For weapons, Seimos Crossbow + Arde can be a really good start. Khasti Bow is a very cheap 2H-Bow at Lv170 even though it comes with nice stats.
Honestly, it’s best you stop there first and focus on upgrading attributes up to around Lv50-70 before investing on gears again.
