Siege Warfare must be the best place to prove your ability. Excellent choice.

Go to Tiamaranta, and join four bouts of siege warfare, one for each heart of Tiamat's power.

If you prove your worth and return to me, I will help you extend your Greater Stigma Slot through a Mysterious Stigma.

Player: Accept.

Wonderful.

If you managed all four bouts of siege warfare, you're more than capable of handling the Greater Stigma.

I'll give you a Mysterious Stigma, so please hold it in your arms for a while, so that your energy is absorbed into it, Player.
