Ok so was going through my phone to upload pic onto my sd so I could transfer over to my new phone and found this old piece of Valentinus spell sword halberd. After looking at this I think I can say my art come farther then I thought.

about the blade
the sword part is made of mythril the sheaf is made of Red Iron the Halberd is made of orichalcum

The symbol on sword from top down are water earth fire and air.
the symbol on the Halberd right to left Is darkness and light. these symbol are to help amply the weapon abilty to cast and hold spells.
important note about this normally these two metals are incredible strong and are known for their magic conductibility.]
Though they do allow great volume of magic, due to them being opposite the metals durability have greatly diminish and are as strong as temper steal instead of their normally stronger then titanium state.
