One of my Kingmaker 2e players has chosen to do a Air/Wood Kineticist for Kingmaker... He brought to my attention that the Feat "Timber Sentinel" will allow him to basically create an entire grove (or even forest!) of trees over a few days time. I cannot seem to find anything to refute this. How would this affect the Kingmaker Kingdom building? I can see him spending a lot of downtime creating forests, which in turn, can be used to build lumbermills, help the local fey, and all sort of potential repercussions.
Sure, the forests will be basically a forest of saplings until they mature (as Timber Sentinel leaves behind a normal tree after it expires). Any thoughts on how to make it that it will not break the game? Thanks!
