Staff of One
Nico's sole weapon is the Staff of One, a magical staff that can cast any spell imaginable, even making Dormammu tremble. The Staff, however, comes with two limitations; first, and more importantly, Nico cannot cast the same spell twice, or the spell will misfire and a random effect will occur; for example, the second time she tried to cast "Freeze", she produced pelicans, and the second time she attempted to cast a "Fumigation" spell, the staff teleported Nico and Karolina miles in the Los Angeles desert. The second limitation of the Staff of One is that it cannot be used to bring people back from the dead. Nico discovered this limitation when she tried to resurrect her Alex Wilder off-panel. Nico revealed this attempt to explain why she could not magically revive the deceased future version of Gertrude Yorkes. Tina Minoru had early mentioned the Staff even made Dormammu tremble, implying that Nico is only scratching the surface of the Staff's true power. Tina is also able to do spells without saying them, as evident when she turns herself, Robert Minoru, and Victor and Janet Stein into their villain costumes. In the Civil War arc, it is shown that Nico does not need to speak English words to cast spells; Nico cast a teleportation spell using a Latin phrase supplied to her by the Vision.
Only Nico can summon the Staff, but anyone can cast spells with it. When not in use, the Staff retreats into her body, which Nico describes as "feel[ing] like I have something in my eye, but instead of my eye, it's... it's my soul." To summon the Staff, Nico sheds blood and unintentionally recites the incantation "When blood is shed, let the Staff of One emerge." Early in volume one, Nico would cut herself to release the Staff, often using Chase's switchblade. As the series progressed, Nico found alternative ways to make herself bleed, including brushing her gums for extended periods of time, having Gert's deinonychus Old Lace bite her arm, and during her monthly menstrual cycle, Nico does not need to cut herself to evoke the Staff. The Staff always emerges from the center of her chest, and passes through any clothing she is wearing without damaging it or Nico. However the Staff will damage anyone or anything directly in its way when ejected from Nico's body. For example, the Staff emerges after the vampire, Topher begins to drain Nico's blood and pierces directly through the center of his chest.
Nico's time with the Witchbreaker has granted her a newer version of the Staff of One called "The Witchbreaker's Staff." Nico can now wield its powers and cast spells with greater proficiency than before.
Fistigons & X-Ray Goggles
In the first volume, Chase stole telescopic x-ray goggles and the Fistigons from his parents' secret laboratory. The x-ray goggles allowed Chase to see through clothing, walls, and even through miles of rock. The Fistigons were metal gauntlets with built-in flamethrowers. The gloves allowed the wearer to mentally shape the produced flame into any form the wearer desired. Before the final fight with their parents, Chase nearly drowned and was too weak to go on. He gave the Fistigons and x-ray goggles to Alex, who subsequently betrayed the team to their parents. Nico used the Staff of One to magically destroy the gauntlets while he was still wearing them, and the x-ray goggles were incinerated with Alex by the Gibborim.
However, in vol. 2 #30, Chase, having traveled back to the future when the Runaways were time-displaced, arrived back in 1907 with the goggles and more powerful Fistigons. He states that he didn't just steal his parent's invention, he studied how they were made, implying that the new Fistigons are mostly his own design. The new updated Fistigons have a wider range of abilities, including being able to fire small rockets and manipulate energy (possibly electricity).
The Leapfrog was the Pride's transport to the Marine Vivarium, where they met the Gibborim prior to the Rite of Thunder. It was created and operated by Victor Stein, and it's basically a flying green craft with bug eyes used for getting around in, and due to its unusual appearance, it has a cloaking device to enable it to pass by unnoticed.
When the runaways took Leapfrog as their own transport after the deaths of their parents, Chase took control of it. However, they didn't keep it long, as they were taken into the custody of Social Services by the Avengers. However, once they fled their respective homes, they found the Leapfrog at the old Avengers West Coast compound.
Leapfrog has lasers fitted to it. These are attached to the craft, but they can also be used as stand-alone weapons, as shown by Victor in shooting the Doombot. Leapfrog was also used to take down Xavin.
Leapfrog has the ability to determine that Xavin's ship missile locks onto it, though its cloaking device was useless against Xavin's ship's scanners. This means that as advanced as Leapfrog is, it's probably just a basic craft that the Pride had built for the occasional trip.
An unusual aspect of the ship is the fact that it can talk. It spoke to Chase, mentioning that it could understand five thousand languages. It has also shown a knack for being tactful, noticable in a conversation with Molly. When Chase decided to take leave from the team, Victor began piloting Leapfrog. The ship can be operated by remote control, as seen when Hunter took control of the lasers. The Leapfrog can also be used as a time machine, when a small device called the Overdrive is placed into its slot.
