Greetings,
I'm looking to buy the Tinker Beginner Class 1 Recharge Cell formula. If no one has one, can you tell me what Mob's to camp to get one? I've found a list online, but a friend and I spent several hours separately killing Mobs and got everything ELSE But the form I need

You can find me in game as Timberlnd - lvl 24 Dragon, Timison - lvl 14 Warrior/Tinker, Timis - lvl 9 Mage, etc...

Thanks,
Timby
