Permanent Legendary Bonuses

The "Legendary" system in Skyrim is, by default, a thin bandage on the leveling soft-cap wound in Oldrim of yesteryear. Example...

A young novice illusionist starts with a few magic tricks (15), and eventually grows into an immensely powerful mind-bender who can befuddle the strongest of opponents (90). Then one day she reaches the pinnacle of her training and becomes a paragon of her craft (100), only to discover that being a truly legendary illusionist means that tomorrow she'll hardly be able to magically calm a carrot (15).

Sound familiar? Why would anyone want to prove how amazing they are by opting for selective amnesia of their primary skills with literally no benefit? No idea.

Permanent Legendary Bonuses aims to fix this by providing a permanent boost to the skill that's being sacrificed, among other bonuses and benefits.

Now when our master illusionist decides to take her craft to the next level, she'll gain a 10-point Illusion skill bonus. She'll still start back at 15, but this time she'll have an additional 10 points of effective Illusion level (15/25). Leveling again to max will be interesting too (100/110). Most importantly, though, this same skill being honed will result in the bonus being stacked for each Legendary. So she decides to go for it again (15/35), works her way up to the top again (100/120). Each Legendary skill gain provides an increased gain in both the new beginning, and in the re-mastery of the skill.

In addition to skill-based bonuses, there are special bonuses applied for the archetypes of skills being sacrificed...

Combat (Archery, Block, Heavy Armor, One-handed, Smithing, and Two-handed) — 5 health and stamina per Legendary

Magic (Alteration, Conjuration, Destruction, Enchanting, Illusion, and Restoration) — 10 magicka per Legendary

Stealth (Alchemy, Light Armor, Lockpicking, Pickpocket, Sneak, and Speech) — 20 carry capacity per Legendary
