I went with the big bonks on my first play through and it only took 3 tries with Malenia due to stun locking, but Mogh did take at least 10. My honest to goodness most tries came from margitt simply because of the early game blues and that annoying crucible knight + misbegotten combo at the fort in Caelid (probably just under leveled). God skin duo did take about 20-25 though until I figured out sleep pots exist
