Udyr can full clear without a leash or a potion and have enough for stalkers+amplifying tome
The path: Starting from bottom side, clear all the small camps all the way up. Then clear both buffs and by the time you're done that gromp/krugs will be alive again. Runes I used: 9 atk speed marks, 9 armor quints, 9 scaling cdr glyphs, 1 attack speed quint, 2 movespeed quint.
