Magic damage is one of the three types of damage in League of Legends. Magic damage is dealt by some items and most champions' (e.g. 
mages) spells.

Statistics influencing magic damage
Most magic damage can be increased with ability power or attack damage in some rare cases, but some cannot be modified, such as 
Bami's Cinder's damage per second or 
Galeforce's active against champions.
The amount of magic damage received is reduced by a certain percentage based on the target's magic resistance. The effectiveness of magic resistance can be reduced with magic penetration.
