Master the Secrets of Unlight and the Artifacts of Ancient Imaskar
Imaskarcanists have learned the ancient secrets of Deep Imaskar, a once-human society living in the deepest depths of the Underdark. Through these eldritch arts—taught to the Deep Imaskari by sentient artifacts called the Imaskarcana - they have mastered the power of Unlight, a brilliant, destructive, and infectious energy that can be used to both heal and destroy. With this power, the Deep Imaskari have launched a war of conquest to bring light to every corner of the Underdark. Each Imaskarcanist must decide for themself whether to aid the conquering army or use their power against it and preserve the comforting darkness of the world below.
Learning the Secrets of Unlight
Unlight is a rare form of magic known to very few.
You can roll on or choose a result from the Secrets of Unlight table to inspire how your character learned about this secret magic.
Secrets of Unlight
| 1d6 | You Learned About Unlight When… |
|---|---|
| 1 | You were taught by a refugee from Deep Imaskar who brought this knowledge to the surface world. |
| 2 | You heard whispers in your dreams in a language you inexplicably understood. |
| 3 | You discovered written records left behind by a long-dead Imaskari wizard. |
| 4 | You were apprenticed to a Deep Imaskari wizard in the depths of the Underdark, but you escaped. |
| 5 | You heard rumors of this power from Underdark refugees, then pieced its secrets together through laborious research. |
| 6 | A mind flayer gave you notes salvaged from a Deep Imaskari whose brain the creature had eaten. |
Level 3: Unlight Adept
You know how to weave Unlight into your damaging spells. When you cast a spell that deals Acid, Cold, Fire, Lightning, or Thunder damage, you can change that damage type to Radiant.
In addition, Dim Light created by spells you cast is Bright Light instead.
Level 3: Unlight Invigoration
You can imbue creatures with Unlight drawn from your own energy, making them stronger and fiercer.
As a Bonus action, choose a willing creature you can see within 30 feet of you and roll one or two of your Hit Point Dice. Those dice are then expended. The target gains Temporary Hit Points equal to the total rolled plus your Intelligence modifier, and until the target has no Temporary Hit Points, it has Advantage on Strength checks and sheds Bright Light in a 10-foot radius.
Level 6: Unlight Restoration
You can wield the restorative effects of Unlight to heal injuries and remove harmful effects. As a Bonus action, choose a creature you can see within 30 feet of you and roll one or two of your Hit Point Dice. Those dice are then expended. The target regains Hit Points equal to the total rolled and sheds Bright Light in a 10-foot radius until the end of its next turn.
If you expended two Hit Point Dice, you can choose to end one of the following conditions on the target: Blinded, Deafened, Paralyzed, or Poisoned. If you do, the target does not regain Hit Points.
Level 10: Secrets of Deep Imaskar
Your research into the secrets of the Imaskarcana grants you the following benefits.
Imaskarcana Lore. You can attune yourself to a magic item as a Magic action. Once you use this feature, you can’t do so again until you finish a Long Rest.
Piercing Unlight. Your spells ignore Resistance to Radiant damage.
Unlight Resilience. You gain Resistance to Radiant damage.
Imaskar Seals. You always have the Glyph of Warding spell prepared and can cast it once without a spell slot. When you cast the spell in this way, you don’t need Material components, you cast the spell as if using a spell slot equal to the highest Wizard spell slot you have. Any previous glyph you created in this way is broken, and its spell ends without being triggered. You regain the ability to cast Glyph of Warding in this way when you finish a Long Rest.
Level 14: Doom of Unlight
You can curse your enemies with corrosive Unlight, and the only escape from the curse is physical violence or an explosive death.
When a creature takes Radiant damage from a spell you cast, you can take a Reaction to curse that creature with Unlight. The creature makes a Constitution save against your spell save DC. On a failure, the creature is cursed. Until the curse ends, the target suffers the following effects:
• The target emits Bright Light in a 20-foot radius.
• Attack rolls against the target have Advantage.
• At the start of each of the target’s turns, it takes Radiant damage equal to your character level.
• The target has Advantage on Strength checks and melee attack rolls.
• If the target hits another creature with a melee attack roll, the target can repeat the Constitution save, ending this curse on a success.
• If the target is reduced to 0 Hit Points, it explodes.
Roll a number of d8s equal to half your character level. Creatures in a 10-foot Emanation centered on the target take Radiant damage equal to the total rolled.
Once you have attempted to curse a creature using this feature, you can’t do so again until you finish a Long Rest or until you expend a level 6+ spell slot (no action required).
