D Tier

Chicken 0 Matic

With this D-Tier passive, each strike from your weapon has a 10% chance of summoning a chicken, which attacks an enemy in close combat. This is clearly not the passive we'd recommend, as the chicken's damage is anecdotal. That's why Chicken 0 Matic is the last item on our mo.co passive tier list.

C Tier

Unstable Lightning

If you don't have a gadget capable of inflicting maximum DPS, then Unstable Lightning won't do you any good at all. This C-Tier passive has a 20% chance of launching a lightning bolt every time your gadget inflicts damage. Suffice to say, it's not the most interesting passive in the game.

R&B Mixtape

If you're playing solo and in a game mode other than Rifts, this item on our mo.co passive tier list won't be of much use to you. The R&B Mixtape can be used to heal you and your team mates, and can be acquired in the early game if it makes you feel better, but we don't recommend it otherwise.

Auto Zapper

Zap a monster every 3 seconds. The auto zapper can stun non-boss enemies. Unfortunately, this gagdet is only really interesting during boss battles, as all zap damage will be inflicted on a single enemy.

B Tier

Healthy snack

This B-Tier passive increases your total HP. Healthy snack isn't the best in our mo.co passive tier list, but you can still equip it in early game to survive longer.

Healthy Charm

Increases the chance of regaining more HP when you or your companion heals by 20%. Once again, this is a good early-game passive, or even if you're planning on getting into complicated boss battles. It's also a passive we'd recommend for solo players.

Smelly socks

Smelly socks from the mo.co passive tier list inflicts constant DPS around you. This passive is only really useful if you're playing with a melee weapon. You'll need to find another item if you're using a ranged weapon.

A Tier

Explode 0 Matic Trigger

We're now tackling the A-Tier passives, which will allow you to make the difference in combat. Explode 0 Matic Trigger can create a chain reaction: if you or your companion kill a monster, the passive will generate an explosion that inflicts damage. And if the explosion kills another monster, the effect will repeat itself.

Unstable laser

The unstable laser in the mo.co passive tier list has a 20% chance of firing a laser at a monster that has just taken damage from your weapon or companion. This is a really powerful passive, provided you use an AoE weapon.

Unstable beam

This is THE passive you'll need for boss battles. Unstable Beam will fire a beam at the first monster hit by your weapon for each attack. This is one of the best passives in our mo.co passive tier list, and can be game-changed in a single-target fight.

S Tier

Vampire Teeth

Here's the best of the lot, the mo.co S-Tier passive that you absolutely must have, whatever your level of play. Vampire Teeth allow you to heal yourself every time you attack. They also heal your companion when he attacks. In other words, you're virtually invincible!

Now you know which items to equip and which to avoid, thanks to our mo.co passive tier list. And if you're still looking for more guidance on how to progress easily in the game, you can always consult our mo.co tips and tricks!
