It doesn’t appear there is a variance in ink consumption with the Fizzy Bomb, regardless of how long it is charged. At all. Not even a little, which is the most interesting aspect of the sub to me, so far.
Doesn’t look like Sub Power Up changes the damage, nor does it increase the effective range of the non-direct explosion hits, nor does it affect time that it takes to “charge” it. It does increase the distance thrown, however, like most other subs. (Anyone feel free to corroborate or correct these assertions, this is just my personal testing with no SPU and all pures of SPU)
Overall interesting and exciting patch, almost moreso than last because we have all but gotten confirmation on a larger series of new weapons going into 2019. Awesome to hear all of your thoughts and opinions, especially from those of you regularly playing these weapons that you’ve gotten kinda surprise variants of.
