NEW DRAGON IDEA
THUNDER(LORD'S) DRAGON
Upon being basic attacked by three different champions proc's a thunder strike on enemy champion for a/b/c/d % of max health/current health as True dmg
Numbers and dmg type depending on balance....
Effect has a 15 sec CD and and a 60 sec CD against the same enemy
Especially with possible removal of Thudnerlords from new rune system this could be a very cool dragon to carry on the legacy but convert it into a more teamfight focused effect to reward focus fire of proper target and tank busting the front line engager.
