Well of Life

A Well of Life is a well blessed by the power of Sha'el-O'maga. Any creature with lower max HP than 40 gains temporary hit points equal to the difference.
Each well of life looks different, as they look as the original well that was blessed. Many Wells of Life were common wells built in tree or stone by humans but claimed by goblins either by force or when they were forgotten by those who lived there many years before.
A few of the wells was beautifully carved fountains, natural springs or rivers.
At the end of the Years of Fear most of the wells had been destroyed. When the humans fought back the Goblins the wells that the Goblins worshipped was often the primary target of the missions. Some of the wells was also destroyed by time or Goblin clumsyness.
The rest had either been claimed by civilized races or forgotten. Those that were natural, like rivers and springs, slowly lost their power and is today meerly known as healthy areas to wise healers. Those fountains and wells that remained became holy places and around them temples were built.
With the years going by the goblin origin of the wells was erased by history and so was the ritual to create them.
