Prerequisites: 5 ranks in any Craft or Profession skill.
Benefit: Choose one Craft or Profession skill in which you possess at least 5 ranks. You receive a +2 bonus on your chosen Craft or Profession skill. Ranks in your chosen skill count as your caster level for the purposes of qualifying for the Craft Magic Arms and Armor and Craft Wondrous Item feats. You can create magic items using these feats, substituting your ranks in the chosen skill for your total caster level. You must use the chosen skill for the check to create the item. The DC to create the item still increases for any necessary spell requirements (see the magic item creation rules in Magic Items). You cannot use this feat to create any spell-trigger or spell-activation item.
Normal: Only spellcasters can qualify for the Craft Magic Arms and Armor and Craft Wondrous Item feats.
So technically what can I build with an Aegis with Master Craftsman? I don't have a spell casting class in my multi class build nor manifester levels. Do I still need Craft Magic Arms and Armor and Craft Wondrous Item feats to build them? What about Forge Ring, Staff, Crystals, Djors, Psionic Wondrous Items.
And since I'm neither spell caster or power manifester can I place the mods the can be used with my Astral Suits in place of spells and powers when making magical/psionic items, weapons and or armor?
