Time Rod

WASD
The Time Rod in WASD is a Protobot exclusive melee weapon that can be bought for 20 volts.

This weapon does around 25-130 damage on hit, 60-231 damage on head, 84-279 on back, and 107-346 on eye.

Upon hitting an enemy, or an enemy grenade, you will be granted 3 seconds of 25% speed increase, which affects all actions such as reloading, planting the bomb, and defusing the bomb. (If a metalface acquires one.)

This weapon is extremely short, causing it to only extend up to 0.8 in-game meters, making this weapon almost as long as the Dagger.

Cobalt
In Cobalt, this weapon is named 'Chrono Rod', and can be acquired in the story mode only from a specific shop.

In survival game modes, the chrono rod can be bought at 'Special Equipment' shops for 350 volts, and 250 on sale.

Similarly to how it functions in WASD, the Chrono rod slows down time around it, and when it hits an enemy grenade or an enemy, it slows them down.

This is one of the few weapons in the melee slot that are unbreakable, with the others being the Phaser, and the Force Device.
