I'd recommend leveling to 55-60 and start collecting quest items such as spider silk (blakatoa range), thousand-year flower sack (gaia woodlands), or about any other rep quest item, sell the stacks for about 350-400 g if not more and while training masteries.
Legacy - Legacy - Legacy
or 60 sprite set
(it is decent if you ask me)
it is really tricky here, so many good combos
1) yellow 2-h sword or its orange variant
2) Bodor triple damage sword + 50 yellow shield (or orange variant)
3) 100% crit hammer + 60 max speed shield
4) Apocalyptic Dragon King Fang + max speed shield for those elusive sins/rangers
as for bow/gun
1) armored sentinel it is still a good choice
2) miracle bow for its "miracles"
but yes absolutely yes, for non-ap buyers farming quest items or acv mo is the way to go in order to get gold. It is going to be tedious, but it pays off.
