Psycho Knife



The Psycho Knife is a Hardmode, post-Plantera melee weapon that has a 2.5% / (1/40 / ) chance to be dropped by the Psycho during the Solar Eclipse event. When holding the Psycho Knife and standing still, the player will quickly enter stealth mode, causing them to turn almost completely transparent, move much more slowly, and no longer be targeted by enemies. It is one of if not the fasted weapon in Terraria.

Stealth mode is engaged gradually over the course of about one second, during which the weapon's stats are steadily boosted up to the following values:
 * Damage +300%: 340 (from 85) /280 (from 70)
 * Critical chance +30: 34% (from 4%)
 * Knockback +100%: 7 "Strong" (from 3.5 "Weak")

Stealth mode is disengaged when successfully attacking an enemy, when switching to a different weapon or when riding a mount. Swinging the weapon alone does not cancel stealth, nor does walking or flying. Standing still again afterward re-engages it. Moving or swinging the weapon during the one-second transition period, however, will cancel stealth mode.

Due to rounding, the Light modifier gives the same speed bonus as Legendary, with fewer other bonuses.

Tips

 * The Anti-Gravity Hook can be used to move faster while in stealth mode; simply hook the floor while in stealth mode and jump, it will boost your movement speed significantly. The psycho knife can be used in Vortex armor stealth mode with high damage while swinging.
