Jsk Duty of the Spellshield

Arcane Aegis
At 3rd level, your Aegis feature is improved. While you are wielding a shield, you can reflect certain spells away from yourself. When you are the target of a spell attack roll and the roll does not hit, you can use your Reaction to empower your shield with a touch of magic and reflect the spell. You choose a new target for the spell that you can see within 30 feet of you. The chosen target becomes the target of the spell, using the original attack roll.

Spellcasting
At 3rd level, you gain access to the Wizard spell list. Your spellcasting ability for Wizard spells is Intelligence. Spell Save DC = 8 + your proficiency bonus + your Intelligence modifier
 * Ritual Casting: As a Spellshield, you cannot cast a spell as a ritual.
 * Spells Known: You know two spells from the Wizard spell list. You learn more Wizard spells as you gain levels with this class (see the Spellshield Spellcasting Table). Any spells you learn using this feature must belong to the enchantment, evocation, or illusion schools of magic.
 * Spell Slots: The Spellshield Spellcasting Table shows you how many spell slots you have. You regain any expended spell slots when you finish a long rest.
 * Spellcasting Focus: You can use a shield as a focus for your Spellshield spells.
 * Versatile Spells: When you finish a long rest, you can choose one Wizard spell that you know and replace it with another Wizard spell.

Spell Attack Modifier = your proficiency bonus + your Intelligence modifier

Versatile Slots
At 6th level, you can convert ability slots or spell slots into one another. During a short rest, you can expend an ability slot or a spell slot of any level to regain an expended ability slot or spell slot equal to half the expended slot's level. For example, you can expend a 2nd-level ability slot to regain one 1st-level spell slot.

Unknown
At 11th level, you can push yourself beyond natural limits to perform your duties. When you use a martial ability or cast a spell that requires an action, you can use a bonus action instead. Once you have used this feature, you cannot do so again until you have finished a short or long rest.

Aura of the Spellshield
At 15th level, you can expend one ability slot and one spell slot to flood the area around you with magic (no action required). You gain an aura centered on you that extends out to 15 feet. When you move, the aura moves with you. At the start of each of your turns, creatures of your choice within the aura, including you, gain the following benefits. These benefits last until the start of your next turn. Your aura lasts for 1 minute, and ends early if you are incapacitated. You can also choose to end your aura early on your turn as a bonus action. When you use this feature, the number of ability slots and spell slots required to use it again increase by 1 each. When you finish a long rest, this number is reduced to 1 each.
 * A creature gains temporary hit points equal to the amount of damage your Aegis feature blocks.
 * A creature gains resistance to necrotic damage.
 * A creature makes death saving throws with advantage.
