Ocean Drake, regeneration effect is stated differently in 6.10 patch notes and in game info.

6.10 Patch notes: "Restores 4/8/12% of your missing health and mana every 8 seconds if not damaged by a champion or tower in the last 5 seconds" In game info: "Restores (4/8/12)% of missing Health and Mana per 5 secondes if not damaged by Champions within 8 seconds"
