Primeval Brooch

Wondrous item, uncommon (requires attunement)

The symbol of some long-forgotten deity is carved on this cloudy piece of obsidian, and it hangs from a rough leather cord. While worn in a desert, jungle, or tundra terrain, the primeval brooch grants you advantage on all ability checks and saving throws versus effects that cause the frightened condition.

When you use an effect to assume the form of a beast, you may choose to assume a wilder, more primeval bestial form. You gain advantage on Charisma (Intimidation) and Wisdom (Survival) ability checks and on scent-based Wisdom (Perception) ability checks in this form. You also gain a +2 bonus to either Strength or Constitution (up to a maximum of 20) or can forgo this bonus cause melee weapon attacks to have disadvantage against you. While in this form, you disadvantage on Intelligence ability checks (if you take a bonus to Strength), Wisdom ability checks (if you takes a bonus to Constitution), or Charisma ability checks (if you decide to have melee weapon attacks to have disadvantage against you).

Epic Attunement. Melee attacks you deal while in the form of a beast deal an extra 2d6 poison damage.
