Tiamat's Bane

Description:

You channel the eternal wrath of Tiamat to permanently curse a single creature within range. The target must succeed on a Wisdom saving throw or be marked by the Dragon Queen. The curse grows in power as time passes, becoming more difficult to endure. Only a Greater Restoration, Remove Curse cast at 7th level or higher, or Divine Intervention can lift this permanent curse.

Initial Effects:

• Draconic Focus: Any dragon or draconic creature within 120 feet of the target has advantage on attack rolls against them.
• Chromatic Weakness: Whenever the target takes damage from acid, cold, fire, lightning, or poison, they take an additional 2d6 damage of the same type.

Long-Term Effects (after 24 hours):

• Everlasting Weakness: The additional damage from Chromatic Weakness increases to 3d6. Additionally, the target has disadvantage on saving throws against acid, cold, fire, lightning, or poison damage.
• Dragon’s Fury: The first attack that hits the target in each round deals an additional 3d6 damage.

Escalation (after 7 days):

• Crumble Under Tiamat’s Gaze: The target gains disadvantage on all saving throws made to resist being frightened or charmed by dragons or draconic creatures.
• Doomed by Dragons: Whenever the target is within 1 mile of a dragon or draconic creature, they automatically sense the target's presence and become hostile towards them.

Ultimate Wrath (after 30 days):

• Tiamat’s Judgement: The target begins taking 2d6 necrotic damage at dawn each day as their body starts to deteriorate under Tiamat’s curse. This damage cannot be reduced or prevented by resistances or immunities.

Removal Conditions:

The curse can only be removed through one of the following:

• Greater Restoration cast with a 7th-level spell slot or higher.
• Remove Curse cast with a 7th-level spell slot or higher.
• Divine Intervention or direct intervention from a god of comparable power to Tiamat.
• The Caster can choose to end the spell’s effects at any time. However, if Tiamat herself wills the curse to remain, it cannot be removed, and the curse persists indefinitely.
