Didact's Signet

"Made by the Didact's own hand to reward his most elite Prometheans. Advanced Scattershot that fires fast-moving, long-range projectiles with stronger homing behavior after ricochets."

- In-game description

The Didact's Signet is a special Z-180 Close Combat Rifle/Asymmetric Engagement Mitigator made by the Ur-Didact.

Design details
The Didact's Signet is a named variant of the Z-180 CCR/AEM, upgraded to fire a quartet of projectiles in a diagonal square formation that have longer range, higher damage, and stronger tracking after ricochets than those of normal Scattershots. It reuses the chassis of a standard Scattershot, albeit with orange and turquoise stripes decorating the weapon, particularly around the barrel and top and rear sections of the weapon.

Service history
During the Forerunner era, the Ur-Didact handcrafted the Didact's Signet as a reward to his most loyal Prometheans.

In October 2558, a copy of the weapon was discovered by Blue Team in the Gateway on Genesis during their quest to confront Cortana. The weapon was later integrated into the 's War Games simulations for use by Spartan-IVs.

Halo 5: Guardians
The Didact's Signet is a special weapon that can be found in the campaign mission The Breaking.

The Didact's Signet is a Legendary Level 5 REQ that gives out 200 REQ Points when sold. It fires a quartet of fast-moving hardlight projectiles that deal extra damage, have a longer projectile range of up to 48.74 m (159.91 ft), travel in a tetragonal formation, and exhibit strong tracking behavior after ricochets. These traits make the Didact's Signet a strong tool for clearing out curved corridors and engaging enemies in tight areas, such as those in the mission The Breaking. With Smart-Link activated, it can perform a one-shot kill on targets up to 20.95 m (68.73 ft) away, outclassing even the Blaze of Glory in range. The Didact's Signet also kills a Spartan in two ricochet shots, which can be further boosted to just one ricochet shot with a Damage Boost on. The weapon has a maximum unscoped range of 13.73 m (45.05 ft) and a Smart-Link range of 18.13 m (59.48 ft).

In Warzone Firefight simulations, Mythic Knight Battlewagon bosses, including the Knight Bannerman, commonly use the Didact's Signet, which can make them dangerous in close to medium range.

Changes from the Z-180 Scattershot

 * Fires four hardlight projectiles that have longer range, exhibit stronger tracking behavior after ricochets, and travel in a tetragonal formation.
 * Increased damage output.
 * Comes with 15 reserve rounds by default, for a total of 20 starting rounds.
 * The weapon's hardlight projectiles immediately vanish after traveling their maximum projectile range, and no sound is made upon doing so.
 * Spartans killed with this weapon may make different death sounds from if killed with a normal Scattershot.
