+    description= _ "When encountering wild Taurochs, Quenoth hunters often observe the curious behavior of particularly stubborn beasts, who will brace their rugged bodies and absolutely refuse to budge when provoked. Though difficult to placate, these Taurochs are sometimes selected by skilled riders for their exceptional resilience. Any warrior who finds their advance blocked by a Stalwart would undoubtedly be wise to seek another path, for trying to displace the beast would be akin to trying to fight a stone wall."+{SPECIAL_NOTES}+{SPECIAL_NOTES_STEADFAST}
