Contrary to popular belief, the Pachy actually better to knockout tames than the Equus. The Pachy induces more torpor per hit than the Equus and the Pachy also attacks over 15% faster. For added knowledge the Packy is also better than the Mantis (with bats), Pulmonoscorpius, and the Beelzebufo. As long as the Pachy is high level with melee damage pumped into it, it will beat any of the creatures I've mentioned with the same level and melee.
for everyoone saying they dont have a charge attack on mobile they do just go to settings and set right or left multi tap to reload/attack 2 then just tap the left or right side of the screen and ur pachy should start to charge thats also how u do barrel rolls on the pteranodon
