Can Sett - Brawler's ability be used multiple times in one turn to stack buffs (e.g., +4, +8, +12)?

Ruling: Yes, Sett - Brawler's ability can be activated multiple times in one turn to stack buffs, as long as you can give him a buff to spend between each activation.

Sequence:

• Give Sett a buff
• Activate Sett's ability
• Give Sett another buff
• Activate Sett's ability again
• Repeat as needed

Nuances:

• Lee Sin exhausts when used, so you'll need multiple buff sources to activate Sett's ability more than once per turn
