That's currently how that shell works. It's the most underused shell because all it has to offer is damage, while every other shell has some sort of meaningless effect that can be applied in certain situations. Frankly, Chain Shell isn't worth setting up for with Overcharge nor firing off with normally. Thus, I propose a single change:

Bonus: (2*Bonus Effect Power)% chance to inflict Stun

At Rank 5 Charged Shot and Rank 5 One Overcharge, this creates a 24% chance of stunning with an Overcharged Chain Shell instance along with an above average amount of damage, which is comparably weaker to an Arbalest's Blowback Cannon (If their sub-weapon is good) but is still viable since it does not take as much setup or luck as a Soldier's Charged Strike Turnover. I believe this would give the shell usage without making it OP, as becomes a high-risk, high-reward shell.

Thoughts?
