- "The Monado Agni provides a high block rate. It is made from hard materials for increased durability. Damage is somewhat unfocused, but block rate is greatly increased."

- Ocean Elixir of Life - From Kyel Lexos at Freight Road in Colony 6, during rain.
- Immortal Moss - From Satorl Tortas at the Altar of Fate in Satorl Marsh during the day or by Armoured Rockwell at Viliera Hill on Bionis' Leg during rainstorms.
- Quadwing Treasure - From Grove Quadwings at Barren Moor in Satorl Marsh at night, or from Rhoen Quadwings at Bone Corridor in Tephra Cave.
This Monado replica, along with Monado Rudra, are among the most balanced and easily obtainable. It has an advantage of at least +20% block rate and +25 physical/ether defence over all other replicas, to the sole exception of Monado Saga. While Saga has an additional +100 physical/ether defence over Agni, it loses 10% block rate and a third slot.
Despite having the worst minimum damage of all replicas, it can achieve near-identical rating to Abyss/Dogma with the addition of a high level Attack Stability gem. This makes it favorable as a more defensive alternative to Rudra (it cannot achieve similar benefits at the price of a gem slot) as an endgame weapon, though if defense isn't an issue Rudra is generally the more superior choice.
