Awakened Blood Fountain Pen

This pen of black with gold trim bears a bone nib with a regal and decadent design. While you are attuned to it, you gain the following benefits.

Infernal Focus. The pen can be used as a spellcasting focus and must be used as the spellcasting focus when using Blood to Component.

Improoved Infernal Resistance. You have resistance against fire, cold and lightning damage.

Infernal Gifts. As a reaction, when you see a creature take damage that you are resistant to, you may remove that resistance from yourself and gift it to the creature taking that damage before they take it. This effect lasts for 1 minute or until you dismiss it as a bonus action.

Infernal Tongue. You can speak, read, write and understand Infernal and Abyssal. In addition, you gain advantage on all charisma checks against internal creatures.

Bloodied Blade. As a bonus action, you can cause the pen to magically transform into a wicked bone dagger. The dagger serves as a magical weapon with a +3 to attack rolls and damage rolls made with it. If you deal the killing blow to a humanoid, you gain 100gp worth of inkblood in regard to the Feed The Focus property of the pen.

Feed The Focus. As a bonus action, you can draw blood from yourself and feed the pen, taking 1d12 necrotic damage, and your hit point maximum is reduced by an amount equal to the necrotic damage taken. If this effect reduces your hit point maximum to 0, you die. This reduction to your hit point maximum lasts until you finish a long rest. This damage cannot be reduced in any way.

Each time the pen is used in this way, it gains 50gp worth of Inkblood, a magical and potent liquid with many properties. The pen can store up to 2000gp worth of Inkblood. If extracted from the pan without being used immediately, the liquid vanishes in a flash of steam. The Inkblood can be spent in the following ways:

Blood To Ink. The Inkblood can substitute the gold cost of copying a spell into your spellbook, provided you are a wizard.

Blood To Component. The Inkblood can be used to replace material components within spells that have a gold requirement. the bloodink is used in the casting of these spells is spent and consumed regardless of whether the spell would usually consume the material component.

Blood To Gold.  The Inkblood can produce an amount of gold equal to the amount of inkblood spent.

Blood To Power. The Inkblood  can be used to bolster a damaging spell or attack. After you hit with an attack roll, you may spend up to 1000gp of Inkblood to deal an additional 1d6 damage per 100 gp of Inkblood expended. This effect can only damage one creature or object at a time.

Curse Of Infernal Blood. Your creature type in now fiend, in addition to any you already have. You count as a fiend for any spells and abilities that affect fiends differently. In addition, you grow horns and a tail and your skin changes colour to either a deep red, blue or purple. If you ever slay a Fiend allied with the arch devil Fenton, your attunement ends immediately and you must make a DC20 constitution save or suffer 5 levels of exhaustion, of which cannot be removed through magical means.
