Auronidus's Soldiers

You create a suit of animated armor that fights for you. Roll initiative for the armor, which has its own turns in combat. It obeys any verbal commands you issue to it (no action required). If you don't issue any commands to it, it defends itself from hostile creatures, but otherwise takes no actions.   If you use a chunk of metal worth at least the amount listed below, the spell consumes the material and gains a secondary effect dependent on the material used. You can only use a single material in this way, and you must cast this spell at a level equal to or higher than the minimum listed in the table below.

Material	Minimum Cost	Minimum Level	Effect
Lead	25 gp	2nd	The armor cannot be detected by Divination spells.
Copper	25 gp	2nd	The armor has Advantage on Initiative checks.
Silver	100 gp	3rd	The armor's strikes count as Silvered..
Electrum	200 gp	4th	The armor hums with polarity. Whenever it hits a creature with its Slam, it deals an additional 1d4 Lightning damage..
Gold	250 gp	4th	The armor emanates a faint solar gleam. It sheds bright light in a 10-foot Radius and dim light for an additional 10 feet afterwards. It gains 5 Temporary Hit Points at the beginning of each of its turns.
Cold Iron	250 gp	4th	If a Fey creature hits the armor with an Unarmed Strike or Natural Weapon, that creature takes 1d6 Force damage.
Mercury	250 gp	5th	The armor ripples fluidly. Its Speed increases to 35 feet, and it can move through a space as narrow as 6 inches without squeezing. In addition, it gains Resistance to Acid damage..
Mithral	500 gp	5th	The armor is incredibly light and has advantage on Dexterity Saving Throws.
Adamantine	750 gp	6th	The armor is nearly indestructible. The armor is immune to all Critical Hits, even those from Adamantine weapons or creatures with the Enable Criticals feat. When reduced to 0 Hit Points, the armor explodes in metallic shards, and each creature within 10 feet of it must make a Dexterity Saving Throw against your Spell Save DC, taking 3d8 Piercing damage on a failure, or half as much on a success.
Platinum	750 gp	6th	The armor is incredibly pure and stable. The armor has Advantage on Saving Throws against spells, powers, and other Supernatural effects.

  At Higher Levels. When you cast this spell using a higher level spell slot, you create one additional suit of animate armor for every two slot levels above its base level.
