Ah, Thank you for reminding me, Shikaze.
Though there are differences from Super Guard and Super Armor
Big Sword and Axe RA give Super Guard. It automatically guard all attack, but the guard can be broken with enough hits (Sub Machine Gun, Bits) or Strong enough attack (can guard against bazooka, but never win against a hammer. Avoid air mines at all cost!).
Hammer, Gatling Gun and Particle Canon (The one shoot pillar) give Super Armor. All damage received is reduced (though not as big as Super Guard) and nothing will stagger you. Note though if you get hit from behind, it will nullify your super armor.
Super Armor is fixed while Super Guard can be enhanced (or reduced
) by your shinki if your shinki have good def and good defensive skills (or bad def and minus defensive skills
For example, my Rin (Yda) with her big sword only can stand one or two hits from ranged and only can stand one hit from melee attack before her super guard broken. On the other hand...
My Erica (Altlene) can plow trough anything with her big sword. I've seen her super guard resist more than two bazooka, hand gun and Sub Machine gun and can resist at least two hit from melee (even a hammer
Though she usually lose to it at the third hit).
