The target is

Holy radiance emanates from you and fills the area.

You conjure a swirling pattern of twisting hues that roils through the air, appearing for a moment and then vanishing.

Range: Special (300 feet)

Area: 20-foot radius cylinder that is 40 feet high

You learn the target item’s magical properties along with how to use them. This spell also reveals whether or not a targeted item requires attunement and how many charges it has. You learn what spells are affecting the targeted item (if any) along with what spells were used to create it.

Alternatively, you learn any spells that are currently affecting a targeted creature. 

You inscribe a message onto the target and wrap it in illusion until the spell ends. You and any creatures that you designate when the spell is cast perceive the message as normal. You may choose to have other creatures view the message as writing in an unknown or unintelligible magical script or a different message. If you choose to create another message, you can change the handwriting and the language that the message is written in, though you must know the language in question.

If the spell is dispelled, both the message and its illusory mask disappear.

You utter the target's name and attempt to bind them for eternity. On a successful save, a target is immune to any future attempts by you to cast this spell on it. On a failed save, choose from one of the forms of bindings below (each lasts until the spell ends).

A cloud of burning embers, smoke, and roiling flame appears within range.

You infect your target with an arcane disease. At any time after you cast this spell, as long as you are on the same plane of existence as the target, you can use an action to deal 7d10 necrotic damage to the target. If this damage would reduce the target to 0 hit points, you can choose to leave it with 1 hit point. As part of dealing the damage, you may expend a 7th-level spell slot to sustain the disease. Otherwise, the spell ends. The spell ends when you die.

A weapon formed from the essence of Hell appears in your hands. You must use two hands to wield the weapon. If you let go of the weapon, it disappears and the spell ends.

When you cast the spell, choose either a flame fork or ice spear. While the spell lasts, you can use an action to make a melee spell attack with the weapon against a creature within 10 feet of you. On a hit, you deal 5d8 damage of a type determined by the weapon’s form. On a critical hit, you inflict an additional effect.
