I like Warframe’s solution to the making-money-on-a-FTP-Game: Pay to win faster.

Everything in the game is available from the get go, nothing is 100% paywalled off, and you can get anything and everything in the game without having to spend a dime. But you can spend money on premium cosmetics, colors, skins, etc which have no gameplay effect, or you can spend money of premium end game content. It’s still available for free, but buying it with premium currency makes it available much much sooner to you than it would be if you grinded your way to it.

There are several issues in porting this design philosophy into conan, however, most notably the fact that Warframe’s stuff is account bound and you lose nothing when you die.
