What to do with a boring plotline?

I completed NaNoWriMo and wrote nearly 70k words, but now I need to think about one of the plots in the Savage Rebellion. What is wrong is that the writing is becoming a chore, and I don’t know if I should continue this plotline or scrap it.

Let me point out why I am not a fan of this plot point. While it is necessary for this stage of the book, the tournament fighting arc, I have lost interest in writing about it. Not only do you have to describe a one-on-one fight, but I have to come up with different ways of saying ‘attack’, ‘ stab’, or ‘thrust’. OMG, it is driving me a little insane.

The other main plot point is more personal to one character and far more interesting. It allows me to express my usual writing style, which I find more engaging with my creativity.

However, I need the first plot point to continue because it leads to uncovering more of the series’ world-building. At the same time, the other plotline is engaging but less crucial to the whole story arc.

I am torn between pushing through the boringness or skipping to the necessary parts of the plot. What should I do?
