Aura of Subjugation: Can the Vizier force enemies to reroll will saves from allied effects? If so, is the Vizier aware of it when an enemy makes a will save against an allied effect?
Path of the Seer: I think you should structure this the same way you structured Path of the Ruler. In other words - "Path of the Seer: {fluff description}", followed by a separate aura ability (with the (Su) tag) that grants the speed increase. That way you won't need the "this is a supernatural ability" explanatory text.
Foresee Conflict: What happens if the Vizier wants to retrain a Teamwork feat that is currently being used as the prerequisite for another feat or ability?
Bangles of the Jealous Seductress:
- The Wrists bind notation should be "[D7, V8]."
- Does the slashing chakram count as magic for the purposes of overcoming damage reduction?
- Does the chakram do (1d4+1)/e, or 1d4 + (1/e)?
Bloody Shroud: Is "darksome energy" a typo?
Collar of Skilled Instruction: Can this be used to
Aid Another In Combat?
Cuirass of Confidence: Does the Diplomacy-AC-replacement ability granted by the Chest bind work on mindless or otherwise mind-affecting immune creatures?
Dark Lord's Ring of Essence Binding:
- What action is required to animate a body with this veil?
- What happens if you target a non-humanoid corpse with this ability?
- What happens if you target a humanoid corpse with the giant subtype?
- What happens if you target a corpse with a size category other than medium?
- What happens if you target a corpse that has racial hit dice, e.g. a troglodyte? Will the zombie keep those RHD as normal?
- Can the Cairn Wights (from the ring bind) create spawn?
- Cairn Wights are intelligent and can speak - do they know anything the corpse knew in life?
- Will a Cairn Wight become free-willed upon the Vizier's death?
Dreamcatcher: I think 3 rounds is too short for this bind - anyone in a 60ft. cone in front of the Vizier will be making will saves constantly. If you spend 10 minutes talking to someone they will have made 30 saving throws, feeling a hostile force or tingle with every success. I would consider anyone who makes their save being immune for 1 minute, 10 minutes, 1 hour or even 24 hours.
Eyes of the Hawkguard: Does the essence ability extend the range of your True Seeing?
Gorget of the Wyrm: Do you choose the shape (line or cone) when you shape the veil, or each time you activate it?
Heart of the Wight: "directly into the core of energy that flows from the wielder's core" sounds odd/redundant.
Horselord's Greaves: Consider making the "AC/saves per essence buff for mounts" ability baseline instead of tying it to each of the binds. This would not only make the veil more attractive for non-veilweaving classes who use mounts but have not accessed their chakras, it would also save you real estate on repeating that same sentence under each of the binds. The need to invest essence for more than minor gains will keep it balanced.
Light Whip: Do feats, items and other modifiers that affect the trip ability apply to the veil?
Riven Darts: Do the darts truly have a maximum range of just 20 feet, or was that meant to be a range increment?
Robe of the Forgotten Deity: Do you get the bonus in darker than dim light?
Snakehandler's Gauntlets: The ability describes the poison from the Hands bind as "magical film," but the poison itself is tagged as (Ex), making it nonmagical. Which is right? Will the poison persist in an antimagic field if already coating a weapon, or is the poison supernatural?
Spiked Pauldrons: Do the spikes count as magic for overcoming damage reduction?
Stone Giant's Girdle:
- The abilities this grants you should be renamed to "Rock Throwing" and "Rock Catching."
- What is the damage of a Vizier's rock throwing ability? For Giants this is
normally based on slam damage, but Viziers don't have a slam attack.
Stormcaller's Band: This should have the [Air] descriptor.
Storm Gauntlets: This should have all three descriptors of the damage it deals. ("See text" might be the easiest way to do this.)
Vestments of the Maharaja: This should have either the [compulsion] or [mind-affecting] descriptors, or both. I would also include the "obviously self-destructive commands are not followed" clause from dominate.
