Well looking back at my buddy George the Huge Awakened Blacksand buddy got me thinking about other things
A 20'-radius patch of black sand can heal
- who is undead
- anyone with tome tainted soul
- anyone under the 2nd level cleric spell: Shroud of Undeath
At 3rd level - the lowest you can cast Blacksand (5th if pure cleric and not domain)
will heal* 1d4/round to the above list, for 3 minutes which is roughly 30*2.5 = 75hp of healing.
If you maximised the Blacksands it would heal 120hp
Note that its 20' radius is about 50 odd squares, so if you had a small army in there, 1 creature per square your healing 3750hp (maxed 6000hp)
Not bad for a 2nd level spell, that is also a column of darkness.
Some one check this out, and I'm not going mad?
