How do I get more skill points in Dai?

I'm really interested in improving my Dai skills, but I'm struggling to figure out how to earn more skill points. Can you help me understand the best strategies to accumulate these points? I've read through the Dai documentation and explored some online resources, but I'm still not clear on the most effective ways to progress. Could you please explain in detail the steps I can take to enhance my Dai proficiency? I'm particularly interested in understanding how to optimize my use of Dai and any specific tasks or challenges that might award skill points. Your guidance would be greatly appreciated as I aim to become more proficient in this area.
