at 18:27, 1st round. u guys knew it already so its fine, just a quick reminder and clarification: yes, cowing: using a weapon that you haven't killed yet, and doing damage or damaging the map like that, it's an instant round loss for the player who did it.
however.
https://www.tus-wa.com/cups/game-237447/there was this match between FoxHound and Irtis, FoxHound used battle axe and cowed the same way, not having killed Irtis' axe worm before. that cowing is acceptable since if u just swing the axe, you don't damage a worm and you don't damage the map, so its fine, like it didn't even happen
it's basically just a turn-waste. otherwise the rules are strict, always keep in mind which weapon you can use
