All details are in the readme on the nexus or in the download, but here we go:
Lizard: Shed Skin. Remove all statuses on yourself, positive and negative, and apply a 25% all resistance penalty to yourself for 2 turns.
Dwarf: Stone's Embrace. Grant a target Stone's Embrace, which increases their physical and piercing resistance by 35%, but reduces their move speed by 75%.
Human: Tactics. For 2 turns, grant an ally +5 initiative, or an enemy -5 initiative. Note: initiative changes don't take effect until the turn after the status is applied.
