So how exactly do I get flames,
Like
Do I need the booster to get them, and how much does a flame cost, etc.

50k-250k it costs

nah, right now with pressing ctrl + l... appears sth that is a flame forge there u can do the flame u want (always if u have mora than 50k at least).

Look around in the Flames board in the market.
Look into becoming a flame forger, costs money to be one and to make flames.
