Sunspear

Rather than a blade, the spearhead is sliver of dark matter which is linked at a quantum level with the matter of the Eversun, a star which was trapped in a distortion of spacetime during an ancient Celestial war, meaning it exists as a star, supernova, and black hole simultaneously.

This solar and temporal energy allows the spear to be converted from solid matter to pure energy at the weilder's command. The spear's mass can also be manipulated, giving it the weight and gravitational pull of a black hole. Due a quantum entanglement effect, when thrown by a weilder skilled in its use, it will always hit its target, no matter what they do to try and dodge or defend against it.

The weilder can also tap into the temporal stasis around the Eversun, moving a target outside time on impact, effectively paralyzing them. However, as they are outside time, they are also immune to any damage while in this state. Additionally, this effect can only be used when throwing the weapon, as if it is used in mele, the wielder will also be temporally displaced, and will be unable to return themselves to normal temporal flow, as they have no time in which to do this.
