Put simply: Perks level up with you. Rather than constantly dumping perks into the bottom of the tree, most lower level perks will level up with your skills all the way to 100. This keeps the early perks from being overpowered, while freeing up more room to spread some perks around, and often making in more rewarding to reach level 100 of a skill. I made this because I had 5 or so perk mods and still wasn't getting everything I wanted from them. There are some other changes throughout like the ability to place up to five runes at level 100 destruction if you have the rune master perk. Detailed list of all changes below. If I don't mention a perk, I didn't alter it, and if I say something like "up to" that means you reach that ability at very high levels of the applicable skill, typically 100. Reccomended for new and low-level characters. Higher level players will need to use console commands if they wish to regain perk points used up on now useless perks, but the latest update has removed effects of unused perks, making it much easier to import a higher level character without becoming instantly overpowered.

Now available in "Lite." Vanilla perk effects only, automatically grants advanced perks after buying the base perk and reaching the required level.
