Pool of Radiance

"Both the Swords of Sanghelios and Covenant use once-forbidden armaments in their bloody civil war. Advanced Fuel Rod Cannon that fires unstable projectiles that leave a dangerous residue in their impact area."

- In-game description

The Pool of Radiance is a special variant of the Type-58 Light Anti-Armor Weapon, which appears in Halo 5: Guardians as an Ultra Rare REQ variant of the Fuel Rod Cannon. Its chassis is exactly identical to that of the normal Fuel Rod Cannon, except that the main housing is now colored crimson red with white and beige stripes and Covenant glyphs decorating the weapon, particularly at the front, bottom, top middle, and top rear stock.

Background
The Pool of Radiance is a named variant of the T-58 LAAW, which fires unstable fuel rods that leave behind dangerous residue in their impact area and have proximity airburst fuses. Both the Swords of Sanghelios and Jul 'Mdama's Covenant faction continue to use once-forbidden armaments, including the Pool of Radiance, in the Blooding Years.

In October 2558, the Spartan-IIs of Blue Team found a copy of the weapon sitting on top of a rocky ledge in an area on Genesis that they passed through on their way to Cortana. The weapon was later added to the 's War Games simulations for use by Spartan-IVs.

Halo 5: Guardians
The Pool of Radiance is a special weapon that can be found in the campaign mission Reunion.

Available as an Ultra Rare Level 5 REQ worth 150 REQ Points when sold, the Pool of Radiance operates exactly identically to a normal Fuel Rod Cannon, except that its projectiles are armed with a proximity airburst fuse. More importantly, the Pool of Radiance does more damage as its projectiles explode three times upon impact instead of once, making this weapon deadly against slow-moving targets and anyone who lingers in the fuel rods' explosion area in a radius of up to 4.05 m (13.29 ft). Its explosions are larger, at 7.1 m (23.3 ft). In addition, the weapon can carry up to 20 fuel rods at once. These improvements make the Pool of Radiance the most powerful of the three Fuel Rod Cannon variants.

However, to balance out the effects of its improvements, the weapon now has a 40% lower rate of fire.

In Warzone, many Legendary Elite bosses use the Pool of Radiance, including Elite Primes and Ranger Commanders.
