You should add rare items/tools/weapons that help build onto the mystic side of Minecraft. I'd like to see more of the magic you find with the magic illagers and ender pearls.
-Destroyer's Crown: a crown that, when worn, the player can "tame" a limited number of hostile mobs and make them attack any other mob as they would command a tamed wolf. Could be found as the rarest item in a Nether Fortress chest or a Nether boss.
-Endshot: a scepter that hurls ender pearls in a straight, more accurate direction, like at the exact block the wielder is aiming at. Could be found in End ships in a 50/50 chance against elytra wings.
-Blazethrower: blasts a wall of fire vertical to the player, setting a line of blocks on fire and any mobs caught in range. Could be obtained from Mob D (the blaze-variant boss mob from Minecon)
-Sandblower: a strange, conical tool that could be found in desert temples. Breaks sand blocks faster than a shovel. Could be handy in finding buried treasure (1.13) Could also knock back mobs.
