The Blood of Old Heroes

Your lineage is a story half-forgotten, whispered in old wars and stranger nights. In moments of crisis, echoes of those long-gone champions flood your limbs with borrowed memories and iron resolve. The Heroes of Old have awakened once again. 

 When you are reduced to 0 hit points but not killed outright, you can drop to 1 hit point instead and immediately make one weapon attack or cast a cantrip before falling prone.
