So the Oracle of Metal can take the following revelation:
Iron Weapon (Su): You can create a melee simple or martial weapon that lasts for 1 minute for every oracle level you possess. This weapon is appropriate for your size and entirely made of metal (even if it would normally include non-metal parts, such as a spear's shaft) but functions as if it were a normal weapon of its type. You are considered proficient with this weapon. The weapon disappears after 1 round if it leaves your grasp. At 3rd level, the blade is made of cold iron. At 7th level, 15th level, and 19th level, the blade gains a +1 enhancement bonus. At 11th level, the blade is made of adamantine. You can use this ability a number of times per day equal to 3 + your Charisma modifier.
I like the idea of summoning weapons as needed so I have been trying to think of clever uses. The obvious ones like reach weapons, or using the special properties of certain weapons spring to mind.
So could my oracle summon a composite strength bow of any rating I desire? I believe so but I am not certain.
A little tricksy but could I also choose to summon a spiked shield?
What other clever uses might be hiding in this ability?
