Dark Harvest Mel
I’m now 1000 LP playing Mel APC, and I strongly recommend Dark Harvest as her best rune for bot lane.
Comet is still decent, especially into engage supports where you’re able to consistently poke out the ADC. But into enchanters, I find it has way less value since they can usually just outsustain your poke.
Dark Harvest into enchanters is op
Dark Harvest feels way better for snowballing and gives Mel an insanely strong mid game. It’s also much easier to stack in bot lane since you have two targets to proc it on.
My current core is:
Luden’s → Shadowflame → Lich Bane
And yes, Lich Bane is a sleeper item. I’ve been having a lot of success with it as my third item.
For % pen, I usually prefer Cryptbloom.
Obviously, play her however you want, but IMO Mel feels much better when you treat her as a stat-check burst mage rather than focusing heavily on CDR. You don’t need to constantly throw out spells just because they’re available.
Be patient with your abilities and look for high-value rotations. You’re playing bot lane, you have a support who can provide setup for you.
DH + full burst Mel APC has been by far my favorite way to play her.
