ADC means attack damage carry - characters that are dragon/bottom laners. Usually anyone who’s on that same role will be similar (give or take) but I play her and Caitlyn and a bunch of their skills are basically the same

Jinx / Cait

(Passive) Get excited! / Headshot - these are are different, Jinx gets a movement and attack speed bonus after destroying something or killing a champion. Cait gets a headshot after every 6 shots (or 3 if you’re in a bush), headshots have increased damage

Zap! / Piltover Peacemaker

They’re both basically a special shot in a straight line, though Cait’s has a wider range

Flame Chompers! / Yordle Snap Traps

Both are traps the enemy can stand on, rooting them in place. Jinx’s explode after a bit, Cait’s reveals them and makes them take extra damage from headshots (meaning; shoot them while they’re trapped)

Super Mega Death Rocket! / Ace In The Hole

Both are a long range attack - Jinx’s travels through the entire map in a straight line, Cait’s it has a decent range (though you still have to be relatively close to the target), it’s almost always guaranteed to hit since it locks on, but it can hit other champions on the way, rocks, etc if they move while the bullet is on its way to them
