I know what Stand still is. AoO with a Reflex Save of DC 10+Damage to stop them from leaving a square you theaten.
That's the 3.5 Psionic version.The Pathfinder version doesn't use Reflex Saves (much less with Damage as DC) - it just WORKS - but only on ADJACENT squares, so you can't lock-down movement in a huge area with a Reach Weapon.
Master craftsman was already revealed during playtest:
It allows non-Casters to create Magic Items if they have high enough Ranks in the appropriate Craft Skill. As with all Magic Item creation in Pathfinder, failure by <5 means the item is cursed somehow.
Strike Back was also already previewed during playtest, it's something about being able to take AoO's or Ready Attacks (?) when opponents with Reach attack you (while they are too far away to hit 'normally')
..."Shatter Defenses" does sound intriguing...
Well if still works like when Jason posted it it should look like this
Your superior crafting skills allow you to create simple magic items. Choose one Craft or Profession skill in which you possess at least 5 ranks.
Prerequisites: 5 ranks in any Craft or Profession skill.
Benefit: Ranks in your chosen skill count as your caster level for the purposes of qualifying for the Craft 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 Chapter 15). You cannot use this feat to create any spell-trigger or spell-activation item.
Normal: Only spellcasters can qualify for the Craft Arms and Armor and Craft Wondrous Item feats.
