kykle - This is going to be a fairly long post, and if
LozHinge the Unhinged believes I am starting to invade on his thread covering GumbyBalboa's road to being a Patriarch, I'll carry on with this discussion on my own thread
http://www.purediablo.com/forums/showthread.php?t=583934
In the meantime, I'll try to cover these two topics you mentioned real quick.
Corpse Explosion - Yesterday while bored at work I was thinking the same thing you were and wondering if I could shave off a few points from CE, the Arreat Summit answered my question here
http://www.battle.net/diablo2exp/skills/necromancer-poison.shtml
On the chart there you can see the increasing radii that adds on with each level (this is common knowledge, I'm sure).
However, many people fail to calculate these radii into the
area of this death circle. Since the area of a circle equals the radius squared times
pi (A = r*r*3.14), let's look at the area calculations each new level can provide:
Levels 1 - 5 - 10 - 15 - 20
Radius (Yards) 2.6 - 4 - 5.6 - 7.3 - 9
"Area of Death (sq. yards) 21.2 - 50.2 - 98.5 - 167.3 - 254.3
The first 10 points into CE only provide for 98-99 square yards in the "death zone" while the last 10 points will give an extra 156 square yards
of
nitro blasting fun! In fact, the last 5 points spent maxing out Corpse Explosion gives you the best
bang for the buck (love that pun!) by packing on an extra 87 square yards of explosive power compared to the puny 50 square yards provided by the very first 5 points invested.
Also, I wanted to point out that several people here on the threads have pointed out that a large CE circle can even hit critters through walls! (unconfirmed).
I've also read somewhere that the 60-100% corpse damage is not random, but is applied according to how close the monster happens to be to the epicenter of the explosion. This is also unconfirmed but if this is true, it would make the 100% corpse damage "inner circle" that much larger.
Golem Mastery - You may be right about leaving only 10 points in GMastery, but I haven't researched this topic thoroughly enough. I could put 10 points in Blood Golem, instead, but I'll need to look into how to balance those 20 points between Blood Golem and GMastery in the best way possible for the most life possible for Gumby, Sparky, and the "glass cannon" Rusty (which, of course, would be used most of the time).
