Anyway, today I finally figured out how to give Ruby wings outside of Amy gifting them via her Sentinel ability. It's actually a pathetically simple solution: just place the wings on her arms. Something I've done for characters before (heck, Ruby has a Rogue using them!), even this particular combat form, but the idea was still something that took thinking on. (It beats her old method, the blood staff divided into two halves, which was more gliding than flying.)
The resulting form, Angel Ruby, is one of her ultimate forms: each feather can launch an arrow, with each arrow holding any combo of abilities Ruby has. Sound familiar? It's basically similar to her Arbalest Armor.
However, the technique isn't exactly an upgrade--it provides roughly the same rate of fire, and with INCREDIBLY increased power, and also VASTLY boosts Ruby's speed and gifting her the ability to fly (not to mention, incredible versatility), all huge advantages, but the drawback is that she lacks good defense (which is the main advantage Arbalest Armor offers).
By the way, that's still a normal Ruby technique--she can activate Dark Aura to turn her wings black, offering an incredible increase in her already-vast strength and speed. Furthermore, each feather/arrow launched remains solid, so when landing on the ground, offers Ruby one of her few zone-control abilities, since each feather in Dark Angel Ruby form will have the ability to create hard light fusions of her illusion/darkness powers...even in broad daylight, one of only two forms in which she can access darkness powers during the day. (The other being forbidden art #3.)
And it gets better: that's just for Dark Aura. She can activate blood daggers to fully unlock her vampire powers: she gains some light armor covering her body, and she gains a 'dagger' in each hand that can offer defense when the wings are on offense and occasionally vice-versa. The daggers themselves are malleable in shape, basically being able to take any form, from dagger to whip to sword, and are capable of being any combination of energy, liquid, and solid, all while being controlled mostly by Ruby's mind, requiring only the slightest of flicks of the wrist/arm to attack as needed.
And they still retain the ability to launch blood bullets. Basically, these blood daggers are the ultimate evolution of her blood staff, having every ability that the blood staff has: the dual wielding, the whip function, the sword function, the ability to have somewhat controlled movements, the ability to launch blood blasts (not mere bullets)--including the darkness slice that is akin to Gary's shield ability--and even to drain enemies by getting a direct hit in and filtering it into Ruby.
The visuals look awesome in my mind, and it makes sense to me as basically being her final combat form. Angel Wings that are actually Wings, merged with her vampire abilities at their peak. Probably would only see use in one or two battles as a result, because duh, near-finale powers are by definition limited to near-finale fights, but I want it to be one of her eventual powers.
