Here are the powers of the Eyes of Vetra-Kali now that they are all activated and socketed in the Sanctum statue.

The Eye of Vigilance- Functions as a Crystal Ball with True Seeing limited to the confines of the Horn. In order to use it, you need to be standing in front of the statue in the Sanctum.

The Withering Eye- Desecrates the Horn, undead and demonkind (fiend) gain +1 on all attacks and saves. Any undead or demonkind created or summoned in the Horn gain +2 HP/HD. Demonkind in the Horn gain Regeneration 10.

The Eye of Hatred- Pulses when divine magic of Good origin is used within the Horn, and directs the Eye of Vigilance to show where it is being used.

The Eyes also power the arcane shield that now envelops the Horn. The shield prevents teleportation and magical messages from passing through. Any saves against Scrying through the barrier are made at Advantage. All of these magics work just fine while in the Horn, just not through it.

The area of the Sanctum, including the balcony, is further protected by an unholy barrier that damages creatures that attempt to cross it. Creatures that attempt to cross it must make a Wisdom save DC 15. Good creatures who fail the save take 4d8 psychic damage, and are poisoned for 1d4 rounds, Good Celestials take 8d8, and are poisoned for 1d8 rounds. Non-good creatures that cross the barrier take 2d8, and are poisoned for 1d4-1 rounds. A successful save halves the damage, and prevents the poisoned effect.

A Dispel Magic will suppress the Sanctum barrier for 1d6 rounds, allowing safe passage for any being crossing it. This barrier only protects the Sanctum, and does not cross the Spiral Stair.

Does this apply to the Nightmare and Hell Hounds now since they are Fiend ie Demonkind?
The Withering Eye- Desecrates the Horn, undead and demonkind (fiend) gain +1 on all attacks and saves. Any undead or demonkind created or summoned in the Horn gain +2 HP/HD. Demonkind in the Horn gain Regeneration 10.

Yes, they all gain the extra HP.

The save and attack bonuses are onky while in the Horn, and they get those too.

You guys have secured the 4th teleporter. Its key word is “Say.”

It sits in the ruins of a keep to the Northwest of the Horn.

The throne is enclosed is a 30ft cube that is filled with water and has a 1 inch air hole on top.

4 Explosive Glyphs cast at 5th level- 1 by the air hole, 3 around throne.

Updated June 15

Amadeus discovered a “Marauders Map” in the Mural Room.

You guys can register each of the inhabitants of the Horn, and their movements within the Horn will be tracked. Unregistered creatures in the Horn show up, but there is no accompanying identification other than the type of creature they are. e.g. undead, aberration, humanoid, etc.

Activating the Map requires a blood sacrifice. It only needs to be activated once.

It requires an action to interface with the map in a meaningful enough way to gain useful information from it.

May activate Guards and Wards type effects through the map. See below for details.

All of the Forsaken and Tim are able to use the map.

Amadeus has discovered that the map mural can be used to cast Guards and Wards as described in the PH with the following changes and restrictions:

Any individual selected to be unaffected by the G&W must be registered with the map.

The wards last for 1 hour.

The wards can’t be made permanent.

This ability can be used only once every 24 hours.

Registered inhabitants-

The Forsaken
Hexor & Vexor
Valek’s men

You may now use any of the teleporters to beam directly to any location inside the Horn as if you are “very familiar” on the Teleport table. This includes the outside teleporter.

The only room that cannot be teleported directly into is the secret treasure room as it is an extra dimensional space.

About half of the outer defense walls fall down.

C-13 The fissure accessing the hidden redoubt closes tight.

C-19 The “ice” floor shatters into thousands of shards.

1-9 The entire west wing of the Death’s Head Tavern breaks off and falls down the side of the Horn. It crashes in a pile of rubble at the base of the Horn.

1-16 The basin of the fountain cracks spilling a hundred gallons of water all over the courtyard. The fountain’s magic is ruined.

1-23 The chute that connects 2-1 to 1-23 collapses. The stairs crumble and fill 1-23 with debris. The bars of the cage are twisted and ruined.

1-27 The hidden stair in the column is exposed.

2-1 The Wall of Stone plug is broken

2-2 Both walls of this guardroom collapse transforming this chamber into a deathtrap. There is a 20ft wide opening into the Hall of Murals.

2-3 The outside wall (south) falls away. There is a 15ft hole in the side of the Horn, 5ft of 2-1 and 10ft of 2-3.

2-5 The metal bars of the cage twist and warp creating a hole big enough for any creature size large or smaller to escape the cell.

2-9 A 5ft hole opens on the outside wall. The rest of the wall is very unstable.

2-15 This room collapses. Anything or anyone in it are buried under several feet of stone.

2-20 The Pillar marked ‘B’ collapses smashing into the double doors. The spiral stair is exposed.

The Marauders Map appears to be working normally.

3-1 Most of the balcony falls off taking most of the Wall of Stone plug with it.

3-2 The curved northeastern wall collapses opening a new entrance into 3-13.

3-7 This room entirely collapses. Anything left in the room is crushed and buried. Fragile outer wall.

3-10 All the cell doors pop open in unison as the ceiling buckles and barely holds. Valin’s chains are still attached to the ceiling hook.

3-11 The entire north wall crumbles and falls into the valley below opening up a new entrance to the Horn. 30ft hole at the curve.

S-1 The half-wall that seperates S-1 from B collapses.
