Illusion Knight

The archetypal Illusion Knight combines the martial mastery common to all fighters with a careful study of magic. Illusion Knights use magical techniques similar to those practiced by wizards, They focus their study on two of the eight schools of magic: Abjuration and Illusion. Abjuration spells grant an Eldritch Knight additional protection in battle, and Illusion spells are used to misdirect their foes making them harder to hit. These knights learn a comparatively small number of spells, committing them to memory instead of keeping them in a spellbook.

Armor Bond

You learn a ritual that creates a magical bond between yourself and one suit of Heavy or Medium Armor. You perform the ritual over the course of I hour, which can be done. during a short rest. The armor must be within your reach throughout the ritual, at the conclusion of which you touch the armor and forge the bond. If the armor is on the same plane of existence, you can summon that armor as a bonus action on your turn, causing it to teleport instantly onto you wearing it.

Spellcasting

When you reach 3rd level, you augment your martial prowess with the ability to cast spells. See chapter 10 for the general rules of spellcasting and chapter 11 for the wizard spelllist.
Cantrips. You learn two cantrips of your choice from the wizard spell list. You learn an additional wizard cantrip of your choice at 10th leveI. Spell Slots. The Eldritch Knight Spellcasting table shows how many spell slots you have to cast your spells of 1st leveI and higher. To cast one of these spells, you must expend a slot of the spell's level or higher. You regain all expended spell slots when you finish a long rest.
For example, if you know the Ist level spell shieId and have a Ist level and a 2nd level spell slot available, you can cast shieId using either slot.

Spells Known of 1st-LeveI and Higher: You know three 1st level wizard spells of your choice, two of which you must choose from the abjuration and Illusion spells on the wizard spell list.
The Spells Known column of the Eldritch Knight Spellcasting table shows when you learn more wizard spells of 1st levei or higher. Each of these spells must be
an abjuration or Illusion spell of your choice, and must be of a leveI for which you have spell slots. For instance, when you reach 7th level in this c1ass, you can learn one new spell of 1st or 2nd leveI. The spells you learn at 8th, 14th, and 20th leveI can come from any school of magic. Whenever you gain a leveI in this c1ass, you can replace one of the wizard spells you know with another  spell of your choice from lhe wizard spell list. The new spell must be of a leveI for which you have spell slots, and it must be an abjuration or evocation spell, unless you're replacing the spell you gained at 8th, 14th, or 20th leveI.
