A bizarre and completely unique shield that functions similarly to a Ninja star. In exchange for having no stat boosts, a speed debuff, much worse damage output, and no stun, the Crystal Shield allows the Knight to temporarily go invulnerable. But not only does it drain MP extremely quickly, it disables all forms of MP healing while active (such as your pet or potions).

Almost complete invulnerability is extremely powerful, in both solo and group roles. The most obvious use is to tank extremely dangerous bursts of attacks. You can be a human decoy where the Trickster’s decoys are ineffective, such as with Treasurer Gemsbok or the Bridge Sentinel’s rage phase. And as the E.Y.E. procs even while invulnerable, this combo can inflict extreme amounts of damage to bosses. Of course, all of these purposes come at your own risk. Many a knight have died attempting to CShield, while wearing another shield entirely.

It is worth noting that invulnerability does not protect the Knight from status effects. Quiet will immediately end the shield’s invulnerability. However, Silence only prevents the shield’s activation, keeping your status intact. And if you are too close to a boss, Paralysis and Petrification may also just force you to Nexus.

There are two SPD penalties associated with this item: one on activation and one on key release. The penalty on release will not occur if the spacebar is still held down when the ability’s effect ends, and unequipping this shield will also stop the second penalty. But if you shield bash before the first penalty runs out, you’ll get a nasty -45 SPD upon key release.

An 8/8 knight with the Keychain Cutlass, Resurrected Warrior’s Armor, and E.Y.E. reaches 522 MP, which is 7.45 seconds worth of invulnerability. Said Knight with UBMP, Mana exaltations, and in conjunction with 9 Max WIS set Paladins with a Scholar’s Seal and WIS/MP effusions, can use the Crystal shield for an insane 16.69 seconds.

In summary, the Crystal Shield is an extremely powerful ability with a lot of potential uses in the right hands, but may also result in a sudden death if used unwisely.

Before Patch X.33.1.0 (May 2020), this item had a Feed Power of 850.
