Ah shite, well ain't that dandy... Ah well, the first thing Aeris would do is think it's a demon and declare a one man crusade against it... Or well 8-9 man crusade along with the enforcers sooo yeah.
His grenade launcher may be useless unless it has special ammo. Fragmentation won't penetrate well. Na, he's gonna ask for a missile launcher with anti-tank missiles.
@Bushman501 That Julia can provide. She'll probably give him Dust Glade missiles. Which are essentially magic exploding tank destroying missiles. It will break through the armour bit by bit if one keeps shooting it in the same spot over and over again.
Longinus's lance probably won't penetrate as much, so throwing the spear is out of the question, the only thing Aeris has that even has the slightest chance of piercing the thing even a little bit are holy projectiles that Aeris can make through Divine Manipulation. The one thing that can make or break this is how fast it can regenerate its armor.
@Liotrent Nothing can break through the Armour instantly. Even Julia will struggle. It will be all about hitting it in the same spot constantly until the armour shatters. This has to be done fast enough before it regenerates.
So essentially they'll attempt to burrow into the armor as much as they can and explode. That will work. That being said demo charges would work but have to get extremely close obviously.
@Bushman501 Yea, once they break through the armour it's vulnerable. Demo charges will be almost impossible to get on considering it will be burrowing underground constantly and popping up to attack. If you played Mass Effect, think of those big worms. I can't remember their names now. It will be similar fighting style.
@Bushman501 It might be better if you pass it off to the few of us who can fly, we can get in and out faster, however Aeris even though he has watched Humanity advance in technology and military might he still has no idea how to activate any kind of explosive, so your other choice is Angela, but I doubt she knows how to activate them either.
On the other hand, I think if we all concentrate fire we can dig out a substantial amount of that armor, the question is can we keep up that fire?
@Liotrent It will be difficult to keep up the fire, as it will try to burrow underground for safety. Julia could use her magic to shoot the charges onto the worm if needed but again she'll most likely give out more powerful explosives as normal ones wouldn't break through the armour.
