How to increase honor points?

Honor is earned from occupying tiles/plots in the world during the Reign of Chaos event. You will get more points for higher level tiles. Keep occupying plots each day. Drop empty ones or low level ones and occupy more when you can. Use the resources to produce the military supplies to upgrade your Base Camp honor structures to let you occupy higher level plots.

You will also earn rewards of honor points for completing certain tasks in the event. Find these in your quest list next to the daily tasks. You get rewards for the first time you take each level of plot and for reaching other levels.
