• Galio does better as a tank than as an AP juggernaut because he has no self-sustain, and he works well with tank augments.⁴
• Aim Galio's E backward, hold W, and use basic attacks between abilities.⁵

• If It's Killing Time's cooldown expires during Hero's Entrance's channel, Galio applies the augment just before its first damaging effect activates.⁶ Patch unknown
• Tahm Kench's 3-second suppression can leave Galio without W's damage reduction when the ultimate damage goes off, if Tahm Kench does not spit him out early. This can happen while Galio is charging W, while W is on cooldown, or during the 2.5-second W linger, regardless of Galio's tenacity.⁷

Galio's W can reduce burn damage and cause negative healing in some games.⁸⁹¹⁰¹¹

• With enough ability power, Galio's W can reduce magic damage by more than 100%; upgraded Firebrand can then deal negative damage, making the heal calculation negative. Galio can reach 0 HP and remain alive for the rest of the fight.¹²
• Galio's passive does not work with Marksmage.¹³¹⁴

• Since patch 26.21, Galio's W shield health ratio is 6–10%, its fully channeled taunt duration is 1 second, and Hero's Entrance's knockup duration is 1 second.³
