I've seen a lot of (unexperienced) players, who would spam Dragon Piercers mid fight although it does less damage than standard combos would output damage. (That even is true for stunned monsters). That's why I decided to do a little guide.

In order to dash dance and constantly executing ALL (guide contains alternative Combos without MBJ too) the given combos, you'll need:

• Set Bonus Constitution +3 in combination with Dash Juice (recommended)
  
• Set Bonus Constitution +5 without Dash Juice
  
• Mighty Bow Jewel (much more variety in combos, see "Combos")

1. Dash shot (Level 3 charge) and
   
2. Spread shot (Level 3 charge) and
   
3. Dash shot (Level 3 charge) and
   
4. Spread shot (Level 3 charge)

OR/in combination with

Without Mighty Bow Jewel you will only use this combo while running out of stamina, because the first spread shot does not consume stamina and triggers your regeneration of stamina, which is absolutely needed.

1. Spread shot (Level 1 charge) and
   
2. Normal shot (Level 2 charge) and
   
3. Spread shot (Level 3 charge) and
   
4. Normal shot (Level 4 charge) and
   
5. Spread shot (Level 4 charge) Warning: the last normal+spread is a level 4 charged shot if you have a Mighty Bow Jewel, otherwise just use the combo without the last 2 combo-elements (s n s).

does much more damage than any Dragon Piercer Build. Even without Mighty Bow Jewel, the remaining combo has a bigger damage output. In advance, you're much more mobile while dashing than while charging a Dragon Piercer.

Don't ever forget to pull out some stones to stun the monster with the following combo:

1. Dash Shot and
   
2. Spread Shot and
   
3. Spread Shot and
   
4. Spread Shot and
   
5. ... (continue as long as the monster is stunned (for stunning it again) or when you run out of stamina)

For a faster stun combo use:

1. Spread (fast spread)
   
2. Spread
   
3. ...

For Mighty Bow Users:

Combo to waste time (example: Landing a spread shot on the hand of Xenoji'va right after the monster recovered from knockdown without lowering the DPS).
You just knocked down Xeno. Than you'll do the following combo:

1. Dash Shot (to get into the spread range of the arm)
   
2. Spread Shot (to waste time and output damage)
   
3. Spread Shot
   
4. Normal Shot (Level 2) Normal Shots for wasting time
   
5. Normal Shot (Level 3)
   
6. Normal Shot (Level 4)
   
7. Spread Shot (Level 4) (should do enough damage and stun (only proven for solo) to knock down Xeno again.)

Current WR with TA-Rules and the mechanics used which are described above:

The fact, that every Dash Shot will be a Level 3 charged shot is the main reason why dash dancing is so good. The spread combo is most likely used when running out of stamina, explained above. With Mighty Bow Jewel it's even better to execute the spread combo, because you'll charge up a Level 4 shot which will do more damage than usual. Furthermore you can fit in 3 Normal Shots to gain some time for the last Level 4 charged Spread, which could possibly stun monsters again.
