The Conjurer's Coat is a reasonably cheap Armor at a cost of 4000 gold. It adds 50 points to Shovel Knight's Magic Capacity as well as ensuring enemies always drop magic jars. The trade-off is that the armor increases the amount of damage Shovel Knight takes in each hit by one (not affected by NG+ or damage multiplying cheat codes). Note that most things deal one damage by default.
These properties means its usefulness fluctuates. On one hand, the extra magic is more useful in the early stages of the campaign when Shovel Knight has less magic, but on the other hand, the extra damage penalty is also more threatening when Shovel Knight has less health. It may be wise to use the Phase Locket liberally to avoid damage as far as possible. On the flip side, in the hands of skillful players who can evade attacks and avoid taking damage, it allows more liberal uses of Relics, such as using the Propeller Dagger aggressively to increase maneuverability and rapidly thrust toward the enemies while regaining magic after defeating each enemy.
It's worth noting that it's far cheaper to get an extra 50 magic through this armor than through the magic capacity upgrades offered by the Magicist, as it cost a total of 10300 gold to boost Shovel Knight's magic from 30 to 80.
While in Pocket Dungeon the Conjurer's Coat is not present, Shovel Knight can purchase its exact same color palette from Myriad.
In Dig, the Conjurer's Coat returns as one of the purchasable armors. Winning a run down The Well with the Conjurer's Coat equipped will reward the Memento Conjurer's Coat Helm, found placed on the shelves of Hoofman's shop.
