Runic Skin is inversely affected by effects that reduce Galio's magic resistance, such as the Abyssal Scepter or Fiddlesticks's Passive. The magic resistance reduction will reduce Galio's ability power for the duration of the effect. When Galio's magic resistance is brought below 0, he will lose ability power. Ability power has a lower cap of 0.
Due to his natural base 30 magic resistance he will begin the game with at least 15 ability power. With the addition of scaling per-level magic resistance, he will gain ~11 ability power at level 18 or roughly 0.6 ability power per level.
On the other hand, Runic Skin is triggered by his own ability, Bulwark, as well as any other effect that gives him temporary Magic Resist. Casting Bulwark right before another ability will, therefore, increase the impact of that second ability.
Active:Galio grants the target allied champion or himself bonus armor and magic resistance for 4 seconds, and heals himself every time Bulwark's target takes damage, though each heal is 20% weaker than the last for each consecutive instance of damage.
Bulwark is an ally champion-targeted buff ability.
Bulwark has no cast time and does not interrupt Galio's previous orders.
Because Bulwark grants Magic Resistance, when cast on Galio himself it effectively grants him an additional 15 / 22.5 / 30 / 37.5 / 45 Ability Power due to the conversion ratio of Runic Skin.

Active:Galio unleashes a gust of wind in the target direction, dealing magic damage to all enemies it hits and leaving behind a directional draft for 5 seconds, multiplying the movement speed of all allies who pass through it, including his own.
Allies who are facing the opposite direction of the draft will not receive the movement speed bonus.

Active:Galio turns into a statue and channels for 2 seconds, halving incoming damage and taunting all nearby enemies for the duration, which they cannot mitigate with crowd control reduction.
When the channel ends, Galio bursts out of his statue form and deals magic damage to all nearby enemies, increased by 10% for each basic attack he received while channeling, up to a maximum 80% increase. If the channel is canceled or interrupted, Galio deals magic damage in a smaller radius.
