The Charging animation for weapons is cool. It's a bright yellow, radiant orb that gradually becomes larger until its signature 'shearing' sound marks a full charge.
However, while impressive-looking, what I'm proposing would change the Charge particle effect in numerous ways.

Alteration 1: Weapon outline particle.
As the Weapon itself is the entity being Charged, it would make sense for the entire weapon to glow instead of just the player's body. I'm talking about the weapon model being turned into a Particle and overlaid on the weapon itself to give the glow effect a more distinct look. The rays of light coming off of the charge glow we have now would also be included in this particle.
The Damage type of a weapon would also play a part, determining the color of the weapon's glow.
Normal would give off a red glow, Piercing would be the color of the current particle, albeit slightly more yellow; Elemental would emit a light green effect, and Shadow would give off a violet glow. The effect would also feature elliptical rings at various Z rotations continuously closing in on the weapon.

Alteration 2: Player outline particle.
The current Player glow is a ball of light. While it is aesthetically pleasing, it could be revamped similarly to the weapon particle.
The player would recieve a Prismatic glow that, instead of being nondescript, would take on the form of their Armor, Helm, and Shield. This would be another overlay, but it would serve as an advancement to the effect. The armor portion would feature prismatic Mist Well particles rising from the feet.

Alteration 3: Particle around the feet and on Battle Sprites.
At the player's feet, the Shadow they cast would be recolored with a Prismatic hue. The edges of the Shadow would send rays of light diagonally upward, and circular rings would enclose on the player's Prismatic shadow. This would occur more slowly than the weapon's rings, giving the effect of the energy rings at the feet having a higher resistance to movement.

Battle Sprites would gain the original Charge particle, albeit prismatic.

Thoughts?
