There are a ton who can do it, and it basically just relies on getting
rather than
.
is FAR more powerful than knife now, because
- They increased the length and amount of the burn.
- They increased the HP recovered from damaging an enemy with it.
If your start red, all you have to do is individually attack each mob rather than focusing on one (ie .... hit both small and large krug, rather than just hitting the Large Krug) This will enhance how much HP you are regaining.
The dual burn from red/trinket is enough to auto attack the monsters to death.
If you do Krugs first, some champs might struggle at Wraiths, so you skip them and go get the Scuttle (if you can) Scuttle will recover you enough and get smite ready for wraiths so you can come pick them back up.
I do this on these champs:

(I don't really play Amumu/Camille/Fiddle/Fizz/Graves myself, but it's viable)
The only champs it has a challenge vs is generally
, and
just takes too long because he's a single target on his entire kit.
Works EXTREMELY well with
for me, because Pyke can just E right from Red into them, stun them, and go to town. You can even make the Pyke clear safer, by being behind their camp, and then Q Hold to pull one of the Krugs over the wall, and then Eing into the camp to engage the other one. This gives you a few seconds where you're only facing one Krug. Takes off a few hits you would have taken.
Eve is just Eve. can run around and heal.
The reason this is important is because Krug XP has massively been increased. Large /Mid are outright higher, and Smalls now range from 7-11 XP each, where they used to just be a flat 7 per small for the entire game.
Zyra can take the camp without even taking damage as long as you use plants to tank.
