It says 398 (shield strength). There isn't a more powerful option. A grade 'A' shield booster puts it up 477.6. I assume that means total is 875.6. Does a shield booster just work or do you have to activate it? I've never used one.
No that 477 is the total strength. Each A booster increases it by 20% of the base strength. What shield generator are you using?
Wingy and I are both running three boosters on our snakes. Thaty's a really nice 60% boost.
For Chucky that would take you to about 637, which is way better
But of course you need to the power to run them. And why Wingy is talking about Overcharging, though I am using a slightly overcharged 6A on my Python, but I don't have it packed with whizbangs like SCBs.
