the two guards are skilled, if not that then at killing. So the nonstandard approach the three used showed to be very effective. I don't yeeting throwables of the poison could have wiped the lord and his guards all at once from the earth. Maybe 2 of the 3 douchebags dead but for guaranteed 3 /3 kills, having poison on neck pelt, knives, and other fallback areas had more of a likelihood to work it seemed.A bit melodramatic no? I guess we can assume getting that poison was no easy task. Still if it was that lethal they could probably just splash them with it by throwing a flask or hell a bucket. They were good with slings, those would work too. I don't know fill a tiny gourd and chuck it at them?
The most disappointing part though is we have no explanation where this indomitable will came from, or even a remark on what they could have been.
