Well i play Galio for a long time so i know few thing about him. He is very good champion and because of passive you don't need too much AP just balance build , he is still a Tank/AP.

9 Greater Mark of Insight (All Builds)
9 Greater Seal of Defense (Against heavy AD)
9 Greater Seal of Regeneration (Are good for mid/top)
9 Greater Seal of Avarice (Suport)
9 Greater Seal of Clarity (New players to Galio)
9 Greater Glyph of Shielding (All Build)
9 Greater Quintessence of Defense (Against heavy AD)
9 Greater Quintessence of Shielding (Against heavy AP)



Well those are per LVL ... I Don't use Flat Runes and i don't know if works...

If you have Flat Runes will be good kinda.

Well are 4 ways to make Galio Runes are :

1. Mid With mana regain.
2. Solo With Hp regain
3. Suport with more armor / more magic resist / greedy for gold
4. Very good Tank

Well if you got more pages for Galio your Rate to win will be like 80%

KEEP IN MIND GALIO Passive Runic Skin give 50 % for every magic resist he have.
