Sable raises the staff and points it out over the lake, angled upward, and:
A huge glowing purple-violet sphere roars out of the tip of the staff and crackles through the air. It's something like a cloud and something like a flame and it makes an incredible noise. Very shortly afterward, it is followed by an arcing shower of small, blazingly bright orange-yellow darts or spears that pass through it on their way to the lake. The stream of spears continues uninterrupted as the purple thing makes its slow parabolic journey. The first bunch of spears hit the grassy shore and explode violently, in tiny bursts of roaring yellow-white flame and crackling greenish-white lightning; then the cloud-bomb finally hits, and explodes much more violently, releasing dozens of pale blue orbs that streak outward in every direction. The spear-stream finally cuts off at the source; the blue orbs fly through the air in seemingly random patterns, then dissolve into thin air a few seconds later as the last spears strike the ground.
The grass is completely undamaged.
Every single Miles present is staring in some flavour of awe.
"I want to annihilate darkspawn with that," says Stalas.
"I don't want to annihilate anything in particular with it but I am very happy that I got to see it," says Mial.
"It's all rainbowy. How do we tell if we can work Terraria weapons?"
She puts the staff away and gets out a shimmering pyramid-shaped crystal, which she aims toward the ground between her and the lake. It hovers in front of her and fires an array of multicoloured beams of light that whirl in a slowly tightening spiral until they finally join into a single rainbow-haloed white beam a good four or five feet in diameter. Where the beams touch the ground, they kick up sprays of dazzling sparks in matching rainbow hues. She stops the beam almost as soon as it coalesces into its final form.
"It's the prettiest! But it eats mana like you wouldn't believe. Mana being the resource you get from eating mana candies and spend to use Terraria magic weapons. Even with the best mana-saving equipment available, I can only keep it going for a few seconds from a full mana charge."
"And you don't have any of that kind of candy on you. How does mana work? How do you charge, how do you tell how charged you are?"
"I have the ingredients to make that kind of candy, actually," she says. "But I forget if I have enough for a full set, and I almost certainly don't have enough for more than two or three full sets, so if a lot of people wanted to be able to use Terraria magic weapons, I'd have to prioritize at least until I figure out if I can go back and get more. Despair monsters seem like a pretty high priority, though. Mana charges slowly with time and there are potions that give a lot back at once and helpful accessories that make it charge faster, and you just know how charged you are. Or at least I do. I don't know exactly which parts of this will be affected by the fact that you're not Terrarian enough to use stacks."
"I wonder what makes a person Terrarian? Presumably you weren't born that way. Maybe we would just need to poke our heads in."
"My hunch is that it has something to do with my island being my island," says Sable. "The soulless person-things there call me by name. When I find an island that looks like it had someone else there who died, that island's soulless person-things call me by their name."
"No, we can go back inside." She lands and folds her wings to her back. They fold up very tidily, despite their size and ornateness.
