mo.co Passive Tier List

Here's how all available passives currently rank in mo.co:

Best Passives in mo.co

Vampire Teeth

Vampire Teeth is unquestionably the most valuable passive in the game right now. It provides life steal on all your weapon attacks, healing you each time you hit an enemy. Your pets also heal themselves when they attack. While the healing per hit might seem small, it adds up quickly, especially with fast-attacking weapons.

This passive is incredibly versatile and useful in practically every situation - solo play, rifts, and especially challenging content where sustain is critical. There's almost no build that doesn't benefit from Vampire Teeth, making it the clear S-tier choice.

Unstable Lazer

Unstable Lazer has a 20% chance to shoot a laser beam at any enemy that takes damage from your weapon or pets. This passive excels specifically with area damage weapons that hit multiple targets simultaneously, maximizing trigger opportunities.

When paired with weapons that have wide attack patterns, Unstable Laser becomes an impressive source of bonus damage. It's particularly effective in scenarios with large groups of enemies, making it a top choice for farming.

A Tier Passives

Unstable Beam

Unstable Beam gives your weapon attacks a 20% chance to shoot a beam at the first enemy hit. This passive really shines with fast-attacking weapons that can trigger it frequently. It's especially powerful against boss enemies where that extra consistent damage can significantly reduce fight times.

Explode-O-Matic Trigger

Explode-O-Matic Trigger causes enemies to explode when killed by you or your pets, dealing area damage to nearby monsters. This passive creates a chain reaction effect that's devastating against groups of enemies, especially when farming regular map content.

It's particularly effective in any content with waves of enemies, as each explosion helps weaken the next targets. While not as useful against single boss enemies, its performance in group clearing scenarios earns it a solid place in the A tier.

Unstable Lightning

Unstable Lightning has a 20% chance to shoot lightning at enemies damaged by your gadgets. Though limited by gadget cooldowns, when used with area damage gadgets like Snow Globe or Pepper Spray, it can provide substantial additional damage.

B Tier Passives

• Auto Zapper: Auto Zapper zaps a random enemy every 3 seconds, dealing damage and stunning non-boss monsters. The stun effect is valuable, particularly in certain challenges. While random targeting can be unpredictable, the consistent nature of the effect means you always have some form of crowd control working in the background.
• R&B Mixtape: R&B Mixtape continuously heals you and nearby friendly players. This passive has specific utility in team content where you're taking on a support role, providing constant healing to everyone around you.

C Tier Passives

• Healthy Charm: Healing Charm gives a 20% chance to increase healing whenever you or your pets heal. This passive is situationally powerful, especially in team content where you're focusing on a tank/healer role. When combined with healing gadgets or Vampire Teeth, it can boost your sustainability. The main drawback is its reliability - since it's chance-based, you can't count on it in critical moments. In most scenarios, direct healing or damage passives tend to provide more consistent value, which is why it falls into the C tier.
• Healthy Snack: Healthy Snack increases your maximum health, providing a survivability boost. While the extra health buffer can help sometimes, it doesn't directly contribute to your offensive capabilities or provide active benefits during combat.
• Chicken-O-Matic: Chicken-O-Matic gives your weapon attacks a 10% chance to summon a chicken that attacks a single enemy at close range. In certain niche scenarios and specific rifts, this passive can contribute meaningfully, especially when combined with items that boost pet damage.

D Tier Passives

• Smelly Socks: Smelly Socks deal continuous damage to enemies at close range. While this passive has specific use cases against chaos monsters, it's limited by its short-range requirement. The damage output is underwhelming compared to other offensive passives.

While this tier list shows the current power levels of passives in mo.co, remember that the right combination for you depends on your playstyle and what content you're tackling. Even lower-tier passives can perform well in the right situations with the proper build around them. What might seem underwhelming now could become meta-defining with the right weapon or gadget pairing. Don't be afraid to experiment - sometimes an unlikely combination turns out to be surprisingly effective.

Keep testing new combinations and sharing discoveries with the community - that's half the fun of a new game like mo.co! still a new game with many undiscovered strategies. The "best" passive for you ultimately depends on your playstyle, preferred weapons, and the specific content you're tackling.
