Great Oaken Cudgel [CARD] (Patreon)

Weapon (greatclub), legendary (requires attunement)

A massive club that carries the might and weight of age. You gain a +3 bonus to attack and damage rolls made with this magic weapon. This great club deals 1d12 bludgeoning damage. While attuned to this weapon you cannot be aged magically. You can still die of old age.

Speak Softly. You gain a +1 bonus to melee attack rolls made with this weapon against creatures wearing metal armor.

Curse: Tree Ring. The first time you are reduced to 0 hit points but not killed outright while attuned to this weapon, you drop to 1 hit point instead and the curse of this weapon extends to you. This item remains attuned to you until you die but the curse remains until this weapon is destroyed.

Each subsequent time you are reduced to 0 hit points but not killed outright you gain a point of Growth and are now a Plant creature in addition to your original creature type. For each point of Growth, your skin takes on an increasingly bark-like texture and your Constitution score is increased by 1 and your Dexterity score is reduced by 1. This effect cannot be reversed unless this weapon is destroyed even if your attunement to this weapon ends.

While attuned to and cursed by this weapon you gain the following traits:

The first time each long rest you are reduced to 0 hit points but not killed outright, you drop to 1 hit point instead.

You become one with this weapon as it fuses with your new form. As a bonus action you can have this weapon form in your empty hand or dismiss it while holding it, reabsorbing it into your body.

You can cast the Speak With Plants spell once per short or long test without expanding a spell slot. You have advantage on Charisma checks on plants and plant creatures.

This item is destroyed if a creature cursed by and attuned to this weapon is the target of the Blight spell cast at 9th level. When the item is destroyed all cursed creatures lose all points of Growth and are no longer cursed.

An ornery and cantankerous old man, Willem was rarely ever unaccompanied by his walking stick, a monstrous piece of wood that towered over his small frame. Over the years he would inevitably butt heads with similarly obstinate folk, the more aggressive of whom often receiving a subsequent beating over the head. Towards the end of his long life, nobody could quite explain how the old man continued to outmatch those in the prime of their careers even as he grew ever older and slower.

One day, he simply never appeared in town again. Those that bothered searching for the old man only found a mighty tree nobody could remember being there suddenly growing beside his home.
