They actually do go up to 6 its just rare to get everything anything above 4. it was a typo I Meant 5 actually sorry
Standing continuous fire only goes up to 4. You're still a damn liar -__-
I've played more than 100 hours and it's one of my favourite bonuses for claws and I've never seen a bonus of above +4 for it, nor have I ever seen anyone even mention it on this board. And it would just be too damn OP as well, since a 6 star range hedgehog claws would probably do close to 7-8 per hit.
