Giant Gem

From KeenWiki

The Giant Gem is an item in the Keen 4 mod The Keys of Krodacia. Magic Gems can be found floating in the sky all over Krodacia. They have life-sustaining properties and if Keen can collect 100 of them, he will receive an extra life. A Giant Gem contains the equivelent of 100 Magic Gems, so when he finds one it immediately gives him an extra life. There are a least 22 (maybe more) of these gems scattered throughout Krodacia. Some of them can be visibly seen, others are hidden in secret areas. Some are easily accessible, others require a secret passage to get to them. Unlike Keen 4 and Keen 6 all extra lives are reachable and committing suicide is not necessary in order to obtain any of them.
