Maxwell Transue Game Sound Design Reel. All sounds are original creations. 
I like to try and use as many original foley recordings in my designs as possible and then supplement with synthesized sounds, and effected samples from my library.  For example: 

-The armor sounds for Azir and his summons are made up of keys, coins, and cookware recordings. 
-The spell cast sounds for Lux contain cymbal and wind chime recordings. 
-The beam cast spells for the wizard in the diablo clips come from hair clippers and blow dryer recordings.
