So since Shark is now rank 15 I just took this idea from sch so here it goes.
Name: Absorber Shield
Type: Special Module
For ships: Shark (unlocked the same way as other special modules such as ODG Mantis, Sword S shield, etc)
Cooldown: 45 seconds
Description: Surrounds the ship with a special shield for 5 seconds. The ship becomes invulnerable and 15% of the damage received while the module is active is used to regenerate its hull.
