How is this?
Equipment: The Gungnir system has two parts. The main segment is the rather hefty silver pistol that hangs at Hikaru's side. The majority of the system's functions reside within the gun, however in order for it to work properly a visual display is needed. To allow for ease of use both in and outside of battle a pair of glasses are wirelessly connected to the feed from the main weapon.
Abilities: The Gungnir system is an attempt to recreate the accuracy of the mythical spear by tapping into the same True Wisdom that Odin does. It has several fire modes, Normal, Armor Piercing, Ricochet, Machine Gun, Explosive, Tracking and Net. The amount of mana that each shot uses can be adjusted on the fly through voice commands, although a base level normal shot will use one percent of a full charge. As a Sacrifice Cauldron the weapon takes small iron ingots inserted into the handle and converts them to mana. In addition, it can allow the wearer of it's glasses to see using a limited form of True Wisdom. Due to mana and hardware reasons the wearer is limited to seeing three vision modes at a time.
I know you seem to think that a power that's not actively combat related is rather useless in a combat RPG, but give me the benefit of the doubt.
I've been RPing for years now, both here and offsite. I know what I'm doing.
