Few other heavy armors give much of an attack boost, so 4 ATK is already decent. Compared to the Fire Dragon Battle Armor, Aegis Armor gives +4 DEF at the cost of -2 ATT, FDA’s other stats, and the fire proc. However, Mad God’s Rage grants a great increase to DPS, especially where you’d be taking lots of damage anyway (e.g. exaltation dungeons, such as Lost Halls and Fungal Cavern). The effect alone adds the same DPS stats that the Gladiator Guard has, which is very powerful indeed.

Note that despite the wording of the in-game description, you do not need to already be below 80% HP in order for Mad God’s Rage to apply. A single, sufficiently damaging attack while you are at full health is sufficient. For example, almost any attack from Oryx 3 himself in Oryx’s Sanctuary is enough to activate this effect.

With good awareness of how to safely activate and exploit Mad God’s Rage, this is easily one of the most powerful DPS-focused heavy armors in the game, rivaling the likes of the Mercy’s Bane and the aforementioned Gladiator Guard.
