Cloyster Weakness

Cloyster's Water/Ice typing leaves it vulnerable to Electric, Grass, Fighting, and Rock. Cloyster's physical bulk (base 180 Def) helps cushion physical weakness hits, but special attackers are the bigger threat.

Pokemon Black 2 / Pokemon White 2

Cloyster Black 2 & White 2 Guide

  • For Black 2 & White 2, we rate Cloyster B-Tier: a solid option in Black 2 & White 2 for the right team. At 525 BST, it fits the hazard setter role. Icicle Spear with Focus Sash is the standard set.

  • In Black 2 & White 2, watch for Raikou (Electric), Venusaur (Grass), and Hitmonlee (Fighting) when using Cloyster. They all hit it super-effectively with STAB. Rock-type attackers are also a problem.

  • Shell Armor protects against critical hits. That's the one you want on Cloyster. Overcoat is the hidden ability. Niche, but it has its uses. Skill Link works too if your team needs something different.

  • Base 70 Speed is workable. Faster than some, slower than many. On offense, Cloyster is a physical attacker with base 95 Attack. Defensively? Enough bulk to take a hit or two. Best used as a hazard setter.

  • In Black 2 & White 2, run Icicle Spear, Shellsmash, Rapid Spin, and Spikes on Cloyster. Icicle Spear is the most common pick at 0% usage. This set covers the hazard setter role with a mix of damage and utility.

Game Availability

One of the original 151, Cloyster has appeared in 20 games — most mainline games. From Red & Blue through the latest titles, it's rarely been left out of a regional Pokedex.
