Recharging Spells (Paraelemental) (EAFW)

Spells may only be recharged when a cleric is in contact with his patron paraelement The time required for meditation is exactly the same as that required for the prayers of the traditional AD&D® cleric.
This can be extremely difficult for a paraelemental cleric since the raw material of his plane is usually found only in certain regions. The priests of Athas have found two ways around this. The first is to gate in material and use it to recharge their spells. The second method—that of remaining physically near the element—is more limiting, but some paraelemental priests rarely stray far from the source of their power. Silt clerics, for instance, are almost always found around the Sea of Silt or the Estuary of the Forked Tongue.
Sun clerics are not so limited. They may recharge their spells simply by sitting beneath the sun for the required time period. Unfortunately, this means that they cannot recharge their spells at night.
Rain clerics may recharge their spells any time a cloud is visible in the sky. On Athas, some sort of cloud is visible 50% of the time. This percentage increases in certain types of terrain. On high hills and over scrub lands it is 60%; over farm lands, 70%; and in forest or jungle areas, 80%.
