Ok, lets say oni charges up a fireball so that it makes it a 2 hit fireball.
if i throw a spark and it negates one of the hits (thus becoming a 1 hit) reflecting it and the opponet gets hit by the reflected fireball it becomes a 2 hit.
not complaining just saying.
old news, but yeah. it becomes 2 hits.
Is it just a two hit “combo” with normal damage from one FB or dose he get the full damge from the 2 hit FB? Maybe this is one hidden effect from soul reflect 
The reflect or EX reflect reflects the fireball at his initial state to the opponent. with same damage (ex for EX that boosts the damage by 5% if I remember correctly)
