This won't help but I was perplexed as well, as I've never heard the term 'ripper' outside the context of Nightmare on Elm Street, 18th century Britain, or a violent farting sessionOk,they're off for lightning, just after a denied try for Dombrandt.
Can one of the bug boys explain what happened there? He's talking about binding onto a ripper, and therefore it's obstruction, but... What does that even mean?
is it that he split out from the maul, but didn't get away from it enough? Which doesn't look right to me - but I fully acknowledge my ignorance of what the big buggers do, though I've generally learned a lot from my decades on forae.
