MH Wilds Waiting Room (Nargacuga Hammer TA) 

This run is done using the TA ruleset which restricts some items, equipment and actions. We turn narga to enrage the monster but we are unable to flinch shot the monster per the ruleset.

Yeah he is legit, one of the best HBG runners with few others even close to his level. He has been grinding G's and EX's nonstop for a few years and knows the game really well. - Zook

Maybe you are right, still i don't know how is possible to make a Nakarkos in solo faster then your Speed Run and less heroic.
