Comeback: Despite being weakened as of 3.0.0 it is still a good ability for aggressive weapons like this
1.4 Quick Respawn: minimize downtime to 6.07 seconds especially for a weapon with minimal range
0.2 Ink Recovery Up: helps you gain more ink for close quarters. 0.2 feels like the magic number to use since 0.3 is barely noticeable and more ink is recovered in kid form by a huge amount (the main weapon recovers ink quickly with no recovery lag)
1.1 Swim Speed Up: Swim speed helps it approach the splat zone or getaway from a tight situation quickly
0.2 Sub Power Up: Gives burst bombs more range to mitigate the main weapon's poor range
as it can be used to pick off the enemy from afar.
