Skulk bites that don' t work?
Yes, it's true. I noticed one game that I was biting a res node and doing no damage, so I experimented with Proximae and Yellow Asterisk, and lo and behold, I was able to do it again.
It is not a range issue, as I get right up to the node as far as it will let me; I think you need to be straight on, though. And then I start biting, and nothing. No damage, no sparks, nothing. You can do it all day, and you will do no damage.
I'm not real good at duplicating it, but now that I know it's there, I'm starting to notice it more. Pay attention to your biting.
I hope this doesn't also happen when biting marines... :(
