5e Features as Magical Weapons and Items - Barbarian

The lack of powers/features/feats available to characters can be quite a jarring difference between modern and old school play. To try and bridge that gap, it occurred to me to create magic weapons and items out of the many features that from 5e that can be used in B/X.

Barbarian

Axe of Bloodlust - Once per turn, an attack that doesn't hit may be re-rolled. In the round this is used, one missed attack against the wielder may also be re-rolled. [Reckless Attack]

Black Cap Mushroms - Eating one causes the character to enter into frenzy where pain isn't felt and their adrenaline is pumping. For one turn, attacks do +1 damage and damage received is reduced by 1. Eating more than one in a day causes a character to fall unconscious for 4d6 hours. [Rage]

Boots of Leaping - When activated, you have a flying speed equal to half your speed. This benefit works only in short bursts: you fall if you end a round in the air and nothing else is holding you aloft. Usable once per day. [Totemic Attunement: Eagle]

Sandstorm Hourglass - When you place this hourglass with the filled side up, a sandstorm engulfs the immediate area. In a 10 foot radius, boiling-hot sand whips around the glass, dealing d3 damage to anyone who enters or begins in that area.

Undying Amulet - When a character wearing the amulet is reduced to 0 HP, the amulet shatters, and the character is left with 1 hit point. [Rage Beyond Death]

Brutal Weapon - Critical hits made with a brutal weapon deal three dice of damage, instead of two. Costs ten times the amount of a regular weapon to purchase from a master smith.

Totem's - I'm too lazy to write them all out, but all the Aspects of the Beast make great magic items.

Next installment will feature Bard-y items
