Heal is a second-level Life magic spell from Heroes of Might and Magic IV. It costs three mana and cures a target of a number of Hit Points based on the level of the caster. Heal is also capable of curing Poison and Plague.
Show me a man who walks into a sick tent with no thought of his own health and I'll show you a brave man.
An upgraded version of Bind Wound as far as health restoration goes, the secondary ability of this spell to remove Poison and Plague is quite useful, since other magic removal spells such as Exorcism and Dispel are ineffective against these curses.
