Similarly, change Sion's "Impervious Foe" to:
"Sion is immune to tenacity down and his tenacity is increased by 20% per active debuff on him. Every time Sion fails to resist a resistable effect his tenacity is increased by 20% (stacking) until the end of his next turn. In addition, he has +100% defense and is immune to Turn Meter removal effects and defence debuffs."
This change has a few benefits for the player experience:
1. Irresistible effects will not increase Sion's tenacity, meaning the player won't accidentally cripple their ability to debuff Sion.
2. Resisted effects will not further increase Sion's tenacity.
3. Debuff-reliant characters will be prevented from becoming TOO powerful.
3. Sion can't be controlled using turn meter removal effects and he will still gain 5% turn meter from the "Fearsome Foe" passive whenever he is damaged. As such, turn meter gain teams will still increase his turn meter whenever he is hit, he won't be turned into the super speed-boosted monster that he can become currently.
