HITDICE

A high number of dice makes for less variance in mobiles hitpoints.
Suggested values are:

       level:     dice         min         max        mean
         1:       1d2+6       7(  7)     8(   8)     8(   8)
	 2:       1d3+15     16( 15)    18(  18)    17(  17)
	 3:       1d6+24     25( 24)    30(  30)    27(  27)
	 5:      1d17+42     43( 42)    59(  59)    51(  51)

	50:    10d169+920   930(923)  2610(2610)  1770(1767)

Diff = max - min.  Mean is the arithmetic mean.
The values in parenthesis are the standard merc values.
