In this way, related perks seem to be along the same 'branch' so all the previous perks would still benefit the player. This means players are less likely to be forced to pick unless perks simply because they're an obstacle to a perk that is desired.
I'm even more curious as to what everyone thinks of this mod than Odin because I'm not completely familiar with all the perk trees. I've had a good read over this mod page and compared it to our Mandate, like Odin, nothing seems out of place. The perk trees that I am familiar with seem to be well overhauled to allow for specific builds. It would cover the perk side of users asking for magic, perks, and more skills. This is another mod in this author's 'vanilla plus' series that is made to work well with Odin.
