Extra Regen

500

More passive healing, great for Mo & Krill as he already has a lot of burst healing, but needs passive in order to get back into the fight quickly.

Sprint Boots

500

Good overall, provides some healing, dmg and movement. Will need for Enduring Speed later.

Mystic Reach

500

All of Mo & Krill's abilities have ranges and this just helps all of them. Very good but can be skipped if needing damage.

Restorative Shot

500

Good for playing under their tower super aggressive, and makes the games super offensive. At best, hitting players off cooldown, is about 6.6 healing per sec on average. At worst, it's 2.5 healing per sec off cooldown.

Torment Pulse

3000

The core of your build, necessary EVERY time. Helps with lanes, kills, farms; does absurd passive damage.

Mystic Vulnerability

1250

This helps with damage on everything you can do spirit damage to.

Active

Fleetfoot

1250

Necessary for overall movement. Same cooldown as T3 Burrow, use with it every time. Make sure to get an armor after buying all of core. Very good for taking on early towers.

Enduring Speed

1750

No other item passive other than Frenzy, which is a 6200, gives this much speed, and its for 1750 total. MUST BUY. Very nice movement slow resist as well.

Duration Extender

1250

Changes a lot of timings in build; Changes T2 Combo from 3.25s > 3.77s & extends both burrow and spin time. Necessary.

Superior Cooldown

4250

Imbue into Combo, very important for overall cooldowns, buy when you feel your cooldowns arent short enough.

Superior Duration

4250

Imbue into Burrow, increases spin and burrow duration. Very good for final build and does more initial damage increase than even Escalating Exposure.

Fortitude

3500

Very good jump in health, and allows for extra movement speed for rotations. Very nice for re-engages.

Improved Spirit

3500

Component of Boundless Spirit, which is in the final build. Increases damage to basically everything and gives some nice overall buffs. Can be waited on if you need other niche items first.

Escalating Exposure

7250

Necessary for drawn out fights and probably the only way people like Tank Infernus and Abrams will die, but not as crucial as it used to be.

Active

Debuff Remover

4250

Very good for really any build in the current meta since there is a lot of Infernus, Haze, Pocket. Good for clearing stuns and status effects.

Soul Rebirth

A second life and you'll likely have your cooldowns back so you'll either get another engage or a clean escape. Can come in major clutch but it is definitely a luxury item.

Active

Divine Barrier

1250

Good for early game survivability, and even more speed. With Enduring, Fleetfoot, and Divine, you'll move 20m/s in Burrow. 22 at T3.

Active

Warp Stone

3000

Really good for base defenses and general movement mid to late game and is the only way you can get some verticality for Burrow. Also give almost the same amount of bullet resist as Improved Bullet Armor.

Bullet Armor

1250

If fighting mostly Bullet on the opposing team, build into bullet armor. Check for damages in the Incoming Damage tab after death.

Improved Bullet Armor

4250

Most of the time you'll want to get Warp Stone before this as it provides almost the same amount of bullet resist and gives some very nice movement.

Spirit Armor

1250

If fighting mostly Spirit on the opposing team, build into Spirit Armor. Check for damages in the Incoming Damage tab after death.

Active

Knockdown

3000

Good for those fliers or really fast movement guys like Paradox.

Active

Ethereal Shift

3000

A very rare buy but good for an insanely oppressive Lash. Takes a spirit slot off so even less likely of a buy.

Active

Slowing Hex

1750

Good for catching up to the really fast dudes like Seven or Paradox.

Active

Silence Glyph

3000

Very nice if you are fighting super fast reactors on the opposing team. Combo is: Scorn > Silence > Exit Burrow > Alchemical > Ult
