1.0 Main Power Up -
Increases the paint output of the main weapon. Which acts as a better substitute for special charge up.
Thermal Ink-
Thermal Ink is very good since the weapon has a difficult time splatting opponents.
This grants the user to see where the opponents are going (for 16 seconds) which can give you the confidence to either approach them or in an organized team setting calling their location to your teammates so that they can do the job for you.
Stealth Jump-
Allows the user to jump in safely and works very well with Quick Respawn and Quick Super Jump.
0.6 Quick Respawn -
Since the weapon has a difficulty splatting opponents more likely the user will die often because of this ability, It is very good for it to have you can add more if you want to shorten your respawn time even further.
0.2 Quick Super Jump -
Allows you to escape from a hairy situation. 0.1 is fine too but 0.2 will allow you jump away from the field or going into the frontlines much quicker.
0.1 Ink Saver Main -
Grants an extra shot for the main weapon. You can use more Main Saver to give yourself more shots to use too.
