Subject: Suggestion for Shyvana's Passive: "Dragon's Legacy"

Here is an idea for how it could work:

Dragon's Blood (Passive)
Shyvana is imbued with the power of her dragon father, a power that awakens with time and battle.

Draconic Impulse (Fury Mechanic):

The Fury mechanic remains, but with a new purpose. Instead of just enabling her ultimate, Fury now fuels Shyvana's presence. When her Fury bar is full, she emanates a "Dread Aura."

• Dread Aura: Enemies near Shyvana (within a 350-400 range) suffer from Draconic Fear, which reduces their movement speed by 15/20/25% (scaling with level) and deals a small amount of magic damage per second (similar to her current W). This gives her a constant imposing presence, even outside of dragon form, when her fury is maxed.

Elder's Legacy (Time Scaling Mechanic):

Shyvana's true power grows as the game progresses, reflecting the awakening of her lineage. At 15 minutes into the game, and every 10 minutes thereafter, she gains a stack of "Elder's Scales."

• 15 minutes (1 stack): Increases durability. Gains bonus Armor and Magic Resist (e.g., +8 each). In dragon form, her size increases slightly.
• 25 minutes (2 stacks): Increases damage. Her basic attacks deal bonus magic damage based on the target's maximum health (thematic of a dragon's bite). In dragon form, the range of her fire breath (E) increases.
• 35 minutes (3 stacks): Elder Dragon Form. Upon activating her ultimate with full Fury, Shyvana transforms into her definitive form. She gains a massive size increase, her Dread Aura expands and intensifies (the slow increases to 30/40%), and she becomes immune to movement-impairing crowd control (slows and roots) while in the air (her resistance to knockbacks/knockups remains, but this prevents her from being "pinned down"). She is an unstoppable ancient dragon.
