I was wondering about when is a good time to figure out a strategy?
Also, what is a good strategy to pick for a beginner?
Tatoo's... Where and when? xD
You can find lesser tattoos at the Armor shop. Check under Quick Links in the left frame. Businesses > Armor
For normal tattoos, look for them in Auctions or FS/WTB forums. If you can't afford one, you could try to rent them.
