Though the Ult Stack buffs are very very nice, This is mostly a counterbuff for the global Health and Ult nerf. Still, you clear the whole lobby in health pool even without too many stacks. Hang in there, Mo will be good... Eventually.0 items

Intro

Hello! I'm Chad, and thanks for choosing my build! Before I get into the Hints and Tips, I just want to thank GodOfDoggos and ReyThePastel, whos Burst build and Ult build both inspired the creation of this build. In fact, this build serves as a marriage of the two build philosophies. The following are in-depth explanations of just about every facet of Mo and Krill's abilities and Playstyle. They're not a terribly complex character, but there is some important nuance that need not be forgotten.0 items

Yellow Canary

So you may have noticed that there is one single Gun item in this build. This is because MnK's Gun is among the worst, if not THE worst gun in the game. With absolutely terrible damage, and a pitiful .08 damage per pellet per boon. Compare this to other shotgun characters like Abrams and Drifter, the dps is so bad. It's so bad, in fact, that although there are gun items that theoretically work well with MnK, like Spirit Shredder, Ballistic and Heroic Aura, his gun is just so bad it's not even worth investing in.0 items

Scorn

Far and away MnK's most important ability. Compared to other Burst characters, like Mina, Apollo, and Pocket, the burst damage is suprisingly mild. Its real claim to fame is its 1.2x Lifesteal. An ability with over 1x lifesteal is actually rare, and that fact, alongside its short cooldown, allow MnK to stay in the fight for a very long time. Additionally, it can be used while burrowed, and even while comboing.0 items

Burrow

MnK's Movement ability. Despite that title, It can actually do more damage than scorn... if used correctly. While not in a fight, this is used to rotate around the map faster than the ziplines can take you. While IN a fight, this is used to rushdown and ambush enemies at the speed of light. Burrow, run up to the enemies, dump your actives on them, pop Scorn, THEN emerge to deal as much damage you possibly can. You actually can use this if you are slowing hexed/movement locked, although you'll still take the movement penalty. Unfortunatley, Burrow doesnt get its CD reduction until T3, and investing into it early can severly neuter your other abilities.0 items

Sand Blast

Why doesn't the damage scale!? There isn't really much to say about Sand Blast. It deals pitiful damage, and disarms enemies it hits. Use it on gun characters. It does exactly what it needs to do and not a bit more. The lack of damage and the fact its CD reduction is at T3 means it's simply not worth investing into at all. HOWEVER, if a double Gun lane is giving you trouble, the T1 Upgrade can really help you due to the range it gives.0 items

Combo

Mo and Krill's Ultimate ability. Locks down an enemy for 2.4 seconds (3.1 at T3) and gives you a Health boon if it kills. Before heavy spirit investment and T3, its damage is not very significant, so this is best used on targets around 30-25% health to secure kills and feed in the process. Let your allies know when your about to ult, have faith in your team, and you can secure a very easy kill. Once you have enough damage on this thing, you can afford to start using this sooner and sooner. Oh, and also, make sure combo is set to "Instant Cast" in the settings, so that you don't skip a beat. In emergency situations, this can (and should) be used to stop enemies ulting or on a rampage. Seven, Silver, Rem, even Mina and Abrams, if you're quick.0 items

Laning Phase

When the game begins, buy Scorn first, then Burrow then Sand Blast. If your enemies are both gun, you can get Sand Blast second. MnK's short range rushdown playstyle means you should play him more aggresively rather than defensively. Get in there, Scorn them both, back out. If the enemies are cowards who aren't leaving the comfort of their Guardian, you should do what I call a, "Hit and Run". Burrow right in there, Scorn the two of them AND their guardian, and back out before Burrow expires. Do that right, and you should heal as much as you took damage. Make sure your also taking Spirit and Regen bridge buff, and stealing their camp as much as you can. Doing this will apply major pressure to the enemy, and hopefully they'll buckle under it. Once you get Combo, It's time to snag kills. Let your teammate know what your gonna do, and grab a low health target with your partner in plain view of them, facetanking the guardian if you have to. Do this right, and Laning Phase is yours.0 items

Post Lane

Whether you Won or Lost the lane, now is the time to start Ganking. Rotate over to the nearest lane and start an ambush. Getting Ult stacks is paramount at this point in the game, so use ult whenever you can guarentee a kill. Once laning phase is officially over for all players we start to act a little more passively. Clear waves, take small camp, clear the odd box, and roam around looking to assist your allies and snag Combo kills. Don't be afraid to help your allies push lanes and Walkers, but do remember that they're not worth dying over. Similarly, if you get attacked by a 1v1 like Abrams, Haze or Drifter, I would reccomend simply running away. MnK is a team fighter, not a 1v1er, you'll be melted very fast since Scorn only has 1 target and Combo has no allies to help it. I suppose I should also mention that Mo and Krill are one of three characters who have access to the tunnels. Despite making them in lore, MnK probably use the tunnels the least effectively. Burrow's long cooldown means you can get stuck there for a very long time, and if you need to run, you're better off retreating to the saftey of you team rather than cowering in the tunnels. The rift I honestly oftentimes have trouble with, due to just how chaotic it can be, but I know for sure that MnK can do exceedingly well here if properly build, so always make sure you're there when your team does Rift.0 items

#Citadel_HeroBuilds_LateGame

Here's where Mo and Krill thrive; the Teamfighting Phase. When a teamfight starts, you need to be there. Dive in with Burrow, Dump your abilities and items on a group of them. Grab as much attention as you possibly can, and if someone stays close to you, then it's Combo time. You will surely kill them if your team is there, no matter how low your target was. Mo and Krill, despite their weaknesses, is a character that demands respect. Your team will gain free space simply by you being there, and so long as you got enough health, then you can stay gaining space until they are all dead. Lather, rinse, repeat as needed, and you should be a pivotal member in your teams success.0 items

Final Statement

Mo and Krill are a character who rank among the worst in the game, but if you play him right, they can easily be the spearhead of your team in the late game, carrying you and your team to victory. If you stayed this long and read the whole way through, then thank you so much! I wouldn't exactly call myself a great build maker, but Mo and Krill are my favorite character to play as, and I just wanted to "nerd out" about him for a little while.0 items
