The interaction between the Doom Guard and the Prideful Soldier was incredibly interesting.
The Doom Guard hosted both Zeigra and Nyxie at equal strength.
The Prideful Soldier primarily held the Solemn Guardian, but was also supplemented by a spiritual mote taken from Zeigra!
Therefore, the two radically-different mechs actually shared something in common!
The presence of the Prideful Soldier excited the Doom Guard's glow by strengthening the strength exerted by Zeigra!
It was as if he suddenly got 5 percent stronger or so. While that didn't sound like much, the perfect balance of the Doom Guard suddenly experienced a disruption!
Zeigra gained the upper hand and pressed Nyxie back. When the latter gave ground, his strong and pervasive ability to inspire terror directly dropped.
