1-24 Quest PL

[Baa]

I would do this:
1-5 - Grind this out in EC using tunnel buffs
5-14 - Bone Chips in Kaladim (approx 80 stacks to do this) - 10pp per stack
14-20 - Orc Scalps in HHP - 10pp per scalp
20-25+ - Left Goblin Ears in HHK - 25pp per ear

I didn't do the scalp part however I just did the left goblin ears for that level range - I think it worked out to be about 100 ears / 2500pp

1-16ish on bone chips is the most economically viable, after that it might be best to buy a bard pl or something
