Assuming if it gets released in the future. Will I have enough hp at late 4th job to get by without washing? Just started out and have no int gears. I might change to Warrior/Bishop. Thanks
No. Unwashed HP for a Bowmaster is very low. Wouldn't even survive with Hyper Body. You'd probably have to resort to Blood Washing (Taking Dex away and putting into HP using AP Resets), use HP gear when fighting or both.
You need minimum 11.5k hp, you won't even be close without washing. http://royals.ms/forum/threads/pink-bean-comprehensive-guide-to-pre-quests-boss.21239/
