Elite Workshop Day 1: What kind of item should we make?

Hydra Helm Wondrous item, rare (requires attunement) Formed from a hydra's skull, this helmet is built to channel its resilience. You gain advantage on saves against being Blinded, Charmed, Deafened, Frightened, or Stunned, and can maintain watch even when asleep. Additionally, your Constitution increases by 2, to a maximum of 20. Curse. The helmet gives its wearer more of the hydra's traits than they may have intended. You grow a second head, which wears an identical helmet. It is generally antagonistic towards the original head, but avoids actively sabotaging them for its own safety. You lose the helmet's bonuses (aside from the constitution buff) if you have less than half your HP remaining, as the other head is knocked unconscious; these bonuses are regained if you regain enough hit points. Additionally, you must consume twice as much food every day to avoid exhaustion.

You cannot target the same creature twice, and any special modifiers applied to the initial shot only apply to 1 arrow. You also do not suffer the downsides of firing this arrow underwater. Once used, the arrow shatters fully, and cannot be fired again.

Hydraslayer's Torch Weapon (club), rare (requires attunement) This club is always wreathed in burning flame, which is able to jump to its targets. On a successful hit, a gout of fire leaps to the target's neck, forming a ring of flame. A target can be affected by a number of these rings up to the number of heads it has. For each ring the target takes 1d4 fire damage at the start of its turn. These rings remain for 3 rounds, or a creature takes its action to tear it off.

Bracers of the Voracious Hydra Style Wondrous item, very rare (requires attunement by a monk) These brass bracers are shaped as the heads of a raging hydra. While wearing them, you gain access to the Voracious Hydra Style, a unique martial art based on the rapid movements of a hydra that grants the following benefits: -You gain a +1 to your attack and damage rolls with unarmed strikes, and they deal piercing damage instead of bludgeoning damage. -When you use Flurry of Blows, you can expend up to 3 additional ki points to make a number of additional attacks equal to the points expended. -You may expend 1 ki point to make an attack of opportunity without using your reaction. -You gain a swimming speed equal to your walking speed and can hold your breath for 1 hour. -Your Constitution score increases by 2 to a maximum of 20.

Hydrafoil Wondrous Item, Very Rare This belt made of leathered hydra hide bears the resemblance of hydra tails wrapped around one another, weaving in and out to make a proper circle. It was fashioned by a great adventurer who sailed the seas on his fast hydrofoil, and sought to replicate that speed on land. When buckled around a creature, 5 long tendrils shaped like hydra heads extend out from the belt and lift you off of the ground. You mentally control these tendrils and move using them, using a movement speed of 5 per head (eg. 25 if you have 5 heads) and ignoring difficult terrain. Whenever you take 10 or more damage due to an attack or spell, reduce the incoming damage by 1 and lose one of the tendrils. At the end of your next turn, two new tendrils bloom from the severed one. This belt cannot have more than 10 tendrils at a time. This belt resews itself each day at dawn, returning to 5 heads. Jewelry of Hydra’s Regrowth Wondrous Item, common This tan metallic string bares 5 metal emblems of reptilian heads, each with a different gemstone for their eyes. When attached around a body part and tightened, you can pluck an emblem from the string to sever the body part from the place where it is attached. This severing causes no pain and you maintain control of the severed body part for 1 minute. After 1 minute, the body part ceases to function and disintegrates to fine dust and a new body part rapidly regrows where the old one was severed. If there is at least 1 emblem left on this string at dawn, the string magically grows new ones until there are 5.

Staff of the Twin Hydras Staff, Very Rare (requires attunement) This staff is adorned with two heads: A pyrohydra and a cryohydra. You can take a special attack action on your turn to unleash the hydras to each attack an enemy within 10 feet. Make a separate melee attack roll for each. On a hit, one deals 1d6 piercing damage plus 1d6 fire damage, and the other deals 1d6 piercing damage plus 1d6 cold damage. You choose which attack deals fire damage and which deals cold damage when you declare the attack. Additionally, when you cast a spell or use a breath weapon that deals fire or cold damage, you can change the damage type to the other. Once you use this feature, you can't do so again until the next dawn.

Hydrequila Potion, uncommon or very rare This highly alcoholic drink is fermented in the gut of a hydra. The uncommon variant has a weaker taste.

The very rare variant has a much stronger, almost caustic flavor, and is a pale golden color. It activated under the same conditions as the uncommon variant, but can activate any number of times within the hour. Curse. When you drink this potion, your guts begin the rumble dangerously. You must eat five days of rations within an hour of the effect ending, or you suffer a level of exhaustion.
