Actually Zero, your soul stone only caused me to get hit for 5,000.
It was raising that other fellow who was Neutral where I lost 2,500 points (I would have lost nothing if he had a soul stone).
Which draws a point: SOUL STONES ARE STILL IMPORTANT!
I cleric of a deity neutral to yours would think nothing of raising you with a soul stone, but without one they may think twice.
I usually raise anyway, but I might not want to raise someone three times during a particularly long quest if it means 7,500 xp when (if that person had a souls stone) it would be no xp loss.
Zero's character hurt my cleric (at a 5,000 xp loss) that led to some good roleplay... a 10,000 point loss would probably led to a more negative reaction.
So please... for the sake of people roleplaying merciful clerics... carry a soul stone.
