Full clear blue side trundle

Runes 3 x Quints scaling armor 9 x Greater armor seals 9 x Greater Attack damage Glyph 9 x Greater Attack damage Mark Masteries: 19/8/3

Must have a decent leash on red to do this. As soon as krugs spawn, smite for the buff, and clear red. Go to Gromp and smite him immediately then clear, Blue buff, Wolves, Birds, Krugs. You can clear the entire jungle up to level 4 if you use the potions well.

Trundle has more than enough sustain to do the entire jungle like this, if you use a lot of your q and w when you have blue buff.

Hope this helps.
