TheBaboom1 gave me the inspiration for this idea. I saw his guide and thought, hmm, what about for Ash? So I went to testing and found a list of the most practical and impractical burst combos Ash has at her disposal.
Note: "Burst damage" is what I consider all within a 2 second time period
1. The Ash Smash
Shoulder Bash (800) + Cannon Shot (400)
Ash's bread and butter combo. This is the one you can pull off the most consistently and is the most efficient burst damage combo Ash has at her disposal as it only uses one ability and 1 ammo. It can be improved however
Kills:
Nobody
2. The Improved Ash Smash
Shoulder Bash (800) + Instant Cannon Shot (400) + Cannon Shot(400)
If you hold M1 (or whatever your fire key is) while charging Shoulder Bash, you will instantly shoot the second your bash ends. Then, while the target is presumably still midair, shoot again for a solid 1600 damage burst. This is extremely powerful especially since most people don't play around a frontline shitting out 1.6k damage in a second
Kills:
Nobody
3. Let there be flight!
Shoulder Bash (800) + Instant Kinetic Burst (450)
While is technically a better damage combo than the basic Ash Smash (whoa +50 damage! This is meta-defining!), it's actually weaker than the improved version since the knockback does stack and will often knock enemies out of range. The knockback is quite useful on maps with lots of hazards like Frog Isle and Fish Market though. Now, if you use Percussion 5 and Furious Charge 5, it's a mini Khan ult. There's no higher damage than insta death.
Kills:
Nobody (potentially UNLIMITED POWER!)
4. Overkill
Shoulder Bash (800) + Instant Cannon Shot (400) + Cannon Shot (400) + Assert Dominance (indoors to be within the 2s threshold) (600) + Instant Cannon Shot (400)
I got lazy so Imma do the ultimate combo and be done with it. Is this combo excessive? Yes. Is it worth using your ultimate for? Probably not. Is it fun as hell? Yes. Yes it is. Nobody expects an Ash to just shit out 2600 damage in two seconds. The ultimate damage combo for Ash.
Kills:
Every non-frontline (not including health boosts)
