Field Medic (Nexus)

You have been specially trained in magical triage and are able to identify the signs of shock and fatigue in those suffering from injuries. You are always ready to provide aid to those in need. You gain the following benefits:

• You can tell by looking at a creature if it is missing any of its hit points and whether or not it has more than half of its hit points. You also have advantage on Wisdom (Medicine) or Intelligence (Arcana or Religion) checks made to determine if the creature is cursed, diseased, possessed, or afflicted by any of the following conditions: blinded, deafened, exhaustion, incapacitated, paralyzed, or poisoned.
• You learn the spare the dying cantrip and can cast it as a bonus action.
• You gain the ability to cast the spell cure wounds without using a spell slot, up to a number of times equal to half your proficiency bonus. You regain all expended uses when you finish a long rest. Wisdom is your spellcasting ability for this spell.
