Lower Water

The cleric casting a lower water spell causes water or similar fluid in the area of effect to sink away. 

Lowering is 5% of original effect for every level of experience of the cleric, i.e. 40% at 8th level, 45% at 9th, 50% at 10th, etc. The effect of the spell lasts for 1 turn for each level of experience of the cleric casting it. Likewise, the area of effect increases by level of experience, an 8th level cleric affecting an area of 8" x 8", a 9th level an area of 9" x 9", and so forth. 

Material components of this spell are the cleric's religious symbol and a pinch of dust.

The reverse of the spell causes the water or similar fluid to return to its normal highest level, plus one foot for every level of experience of the cleric casting it.

Except as noted above, and for the facts that the reverse spell raises water only ½-ft per level of experience of the spell caster and the material components for the spell are a small vial of water and a small vial of dust, it is the same as the fourth level cleric spell, lower water (q.v.).
