Bronze hammer theoreticals:
15 base resists
11 from exceptional (6 base, plus 5 for GM Arms Lore*)
13 from Valorite ingots.
Mage Armor from being Exceptional Samurai Empire Platemail types
45 from 3 maxed Resist properties
= 84 resists, no other special properties except those of Mage Armor from the type made, and 50% extra durability from Valorite.
* Add 3 more resists on Siege Perilous, as its Arms Lore bonus is 1/12.5 skill instead of 1/20.
For each additional property, instead of resists, subtract 15 points.
For something a little more wearable, calculated for gold, with one extra property....
Bronze hammer theoreticals:
15 base resists
11 from exceptional (6 base, plus 5 for GM Arms Lore*)
6 from Gold ingots (And the gold properties).
Mage Armor from being Exceptional Samurai Empire Platemail types
30 from 2 maxed Resist properties
= 62 resists, plus Mage Armor, 40 Luck, 30% Lower Requirements, and one other property, per piece. This is sufficient to be able to craft an all-70s suit (though you'll want to go tailor runic for the gloves, for leather gloves, leather ninja mitts or leaf gloves, to go with the mage armor suit).
Tailored gloves will also let you fudge the resists a bit, as a horned runic item can have up to 76 resists, 40 luck & 1 other property made with a horned kit from spined, 82 resist with horned, 83 with barbed - add another property, or another 15 resists for barbed kit. Hell, theoretically, with only resist properties, a Barbed runic Barbed leather piece can hit (15+11+12)=113 resists, 116 on SP.
