Improving Stick Merge Online Skills?

Hi everyone,

I’m curious about the best way to develop stick merge online skills . Do you focus on upgrading combat abilities, merging efficiency, or balancing both? It feels like skills really determine how quickly you advance in the game, and I’d love to hear what worked best for you.

If there’s a skill tree or specific path that makes the most difference, please share your experience. It would definitely help me and others plan our progression more effectively.

Thanks in advance.
