Warlock Patron: The Deep Well

You have peered into the well of knowledge and kept a grasp on your sanity. An elder being has decided to reward your curiosity with wonderous powers. He does not ask for much in return for these powers, only that you seek knowledge and provide it to him. The powers he grants the warlock include honing the mind beyond mortal limits and control over his servants.

Expanded Spell List

The Deep Well lets you choose from an expanded list of spells when you learn a warlock spell. The following spells are added to the warlock spell list for you.

Deep Well Expanded Spells

Spell Level Spells 1st disguise self, dissonant whispers 2nd detect thoughts, knock 3rd servants of the well, mind shatter 4th greater invisibility, evard's black tentacles 5th legend lore, seeming

Eldritch Knowledge

Starting at 1st level, your keenly honed intellect grants you proficiency in the Arcana, History, and Religion skills. If you already have proficiency in any of these skills, your proficiency bonus is instead doubled.

Arcane Reflex

At 6th level, you learn to protect yourself and the knowledge you've collected. After finishing a long rest, you can prepare an illusion spell from the wizard spell list of level no higher than 1/3 your warlock level that you can cast as a reaction. This spell does not use a spell slot and can be used once before a long rest. The wizard spell does not have to be from the warlock's known spell list. The prepared spell can be changed during a short rest, but not if it has already been expended.

Expanded Mind

At 10th level, your mental prowess starts to rival all but the most powerful spellcasters. You can now maintain concentration on two spells at the same time. The levels of the spells you are concentrating on can be a combined level of 1/2 your warlock levels. While you maintain concentration on two spells, any time you make an action other than a move or dash action, you must make a DC 15 concentration check. Concentration checks from taking damage are DC 15 or half the damage taken, whichever is higher. If you fail the concentration check you lose concentration on both spells. You can drop concentration on either spell as a free action.

Pierce the Veil

At 14th level the Deep Well imbues you with the ability to see through any magic that would shield knowledge from you. As an action, you can gain truesight for 30 feet and darkvision for 120 feet that lasts for one minute. This ability can only be used once and is regained after a short or long rest.
