[Gameplay] Soraka Max Health Cost on Astral Infusion (W)

Her W (Astral Infusion) states:

COST: 10% MAXIMUM HEALTH + 20 / 25 / 30 / 35 / 40 MANA PASSIVE: Each enemy champion hit by Starcall heals Soraka, increased by 1% for every 1% of Soraka's missing health. ACTIVE: Soraka blesses a friendly unit, restoring its health. Astral Infusion cannot be self-cast, and nor can it be cast if Soraka is below 5% of her max health. So, it costs 10% Max health, but cannot be cast when below 5% max health. What about the gap between 5-10% max health? If I cast it with 7% of my max health, do I die?? The answer is no. I just tested it in a custom, and the cost is reduced. I couldn't test if the healing done was reduced, as I am lazy. But still... This should all be fixed for clarity. Don't you think?

I will follow up with further testing
