ToME: the Tales of Maj'Eyal

The tooltip claims I regen a new bone every 5 turns, but this is clearly not the case...more like 15 or 30. Not wanting to just hit "5" and count to myself....does anyone know how long it takes to regen?

Cheers.

The time needed to refresh a bone shield doesn't automatically correct itself as you level up the talent, as I recall, so you need to deactivate then reactivate it in order to have the correct refresh rate.
