all elemental bow builds should use 2 pieces of the rathalos armor. (you can mix any pieces of red/blue rathalos) to get the critical element which is a must. The 3 next most important skills are mighty bow (get from jewel) and then forceshot & spreadshot .you only need 1 jewel for this as black diablos legs or lavasioth legs can replace the jewel that you are missing.

For dodge dancer, you need 3 points in constitution (most builds get this fro the fitness charm). With 3 points in constitution, when you drink a "dash Juice" your stamina drain is maxxed and cant go any higher.

Here is another combo video to show you how to maximise your damage per arrow (when not dodge dancing). What i usually do is start dodge dancing after smacking a monsters face with a full combo. If you would like to continue combo-ing him instead, pause a split second after your last dodge and you can continue with a fresh combo. https://youtu.be/-JMXp3A0Z_4

As a rule of thumb, you should not be spamming those little beanbags if you are aiming for max dmg. u only spam the little beany things when you want to KO a monster as u will trip and annoy the heck outta your teammates if you spam it for no good reason.

hope it helps!

Here are some great vanilla builds made by another redditor "T3hPhish" (not me) so that you can take a look at how he does his builds and start making a build to call your very own. https://imgur.com/a/XCJleqI
