Hero health and regeneration
In a battle the hero loses as much health (in %) as its army loses troops. Health regrows 10% per day plus 5% per Regeneration point, times 100 on this world.
Example: the hero's army loses 30% of its troops, so the hero loses 30 health.
On this x100 world the base regrowth is 1,000% per day: about 42% per hour, even with 0 Regeneration points.
Health regrows only while the hero is alive.
At 0 health the hero dies. See Hero death and revival.
