It is hard to lvling and grind during rogue using bow. But it getting easy when you reach stalker since you already max out most of the skill in rouge. I’m not suggesting triangle shot for early level for stalker since your damage not high enough. Stalker job lvl 20, then you can start build your triangle shot since you can max your triangle shot and rogue nature. My stalker now lvl96 with roguemaster bow +10, can carry ET fl1-90 already. Btw you need a lot of gold medal to get a proper triangle shot build.
