Create some Achievements for your favorite champions
So I believe that League could use some achievements to freshen up the way people play so I thought I'd draft up some achievements people could go for.(Maybe attach it to champ mastery?)
Try to make the achievements in a way that anyone playing the champ could get them without doing something that would be counter-intuitive or way outside their normal gameplay
Mine
"Brush with death" Save an ally from death with your Chronoshift .5 seconds or less from when they would be killed.
"Bomb Squad" Detonate a two-Timebomb combo on an ally that stuns at least two enemy champions.
"Cant be Killeaned" Win a game where you never die.
"Cosmic Wanderer" Collect 100 Chimes in a winning game.
"Dangerous Travel" Kill or assist in killing an enemy champion who has traveled through your Magical Journey in the past 10 seconds.
"Divine Intervention" Stasis 4 or more champions with one cast of Tempered Fate.
"Mushroom Country" Have at least 20 Noxious Traps active at once.
"Unpleasant Surprise" Kill an enemy Champion 5 or fewer seconds after Camouflage ends.
"Just Obnoxious" Kill an enemy champion 3000 or more units away with a Noxious Trap.
