Mar Checks SEVERAL mana types which are crucial to this project.
Thaum>Gold>Obsidian: (7, 12) This Mana type produces a Yellow Stone, which glows slightly.
Thaum>Gold>Heartless Metal Armor: (20, 16) This Mana Type is a Solid Golden Mana, which repels Evil.
Thaum>Gold>Adamantine Ore: (8, 19) This Mana type decreases the amount of light an object absorbs.
Mar Commissions some help from LOTUS and Isobel, they are the ones benefiting after all, and they are surely smart enough to offer aid.
"The first, second, and third stages of magic by proxy are precise explanation of results, so I will avoid telling you anything you don't have a concept for, and instead offer the results and practical knowledge I have."
"This device will be made of a Glowing yellow stone, and have the ability to self repair damage, it's power supply will be mana from this shard of reactive material, and it will speed you up by firing a chain caught in a Hard Mana Rod so that it pierces a target, then pulls you towards it."
Mar demonstrates his thoughts with a Glass Mana Hologram, emitting his Designs for Lotus and Isobel to alter as they please.
"The Hard Mana the chain is encased in dissipates on contact with air, and with a spring mechanism made from one of the armor plates, it can retract as well."
"In order to prevent Mana corruption from the Reactor Mana being different and having different attunements, I will have the Reactor Mana first attune to Gold Mana, since Gold is a Precious Material which attunes all mana to a type closer to itself. The actual Chaingun is made entirely of Solar Material and small Sample Materials, such as Gold, Obsidian, and reactive Material. If you were more experienced in designing with Synthesis, I would probably forgo using A solid Chain at all, and instead just have the obsidian synthesize it from Solar Stone, but neither myself nor you have experience in silicon mana synthesis, so I won't bother."
"So, in Layman's Terms, It is a thing you slide over your arm, which shoots a long chain encased in a rod, and the rod dissolves in the air, then when it dissolves, the chain retracts, after having been shoved into something by the hard rod. I only Lack a Sharp Point to add to it, but I will simply use an Obsidian Biface for the Hook itself."
