First, a big thanks to Griffley, who inspired me (and many other hunters) to try this tame.
Finally after hours and hours of trying, here he is:

My Immo Trap alone wasn´t able to kill the Wolf, so i put my weapon away and gave him one punch before using the immo trap.
Started the tame at the first tick (crit punch) or the second tick (non-crit punch), which was the winner.
Thank you so much for everything, i love this community but never had anything to post.
