Sorcery Clans algorithm:

Multiple Medical Skill * Medical Power to get total medical healing “points” (?)

Injured soldiers need healing with difficulty based on their injury level:

• Uninjured: 50 mp for 50% chance to heal 1HP
• Injured: 100 mp for 90% chance to heal 1 HP and 50% chance to heal 1 level
• Wounded: 150 mp for 90% chance to heal 1 HP and 50% chance to heal 1 level
• Critical: 200 mp for 90% chance to heal 1HP and 50% chance to heal 1 level

In other words, the total MP dedicated to a soldier reflects the % chance to heal 1 HP (but capped at 90%). Also for the three injured levels, the MP divided by the number of the level reflects the % chance (capped at 50%) to heal by a level

INTERESTING WRINKLE: If a soldier is critically injured but receiving top quality battlefield care, it should still take them a while to heal! Maybe there’s a tally on last heal or something…
