So what's the story on this rapid succession of deaths?
Let's see...
1) Fighter, charged up to a bloodmage (evil necromantic PrC), copped a harm for his trouble. Fighter failed his save, took 140 points of damage, and died.
2) Berserker, already heavily wounded, attacked an enemy archer (actually a former PC who went bad). Archer got off her readied shot, berserker took ~20 hit points + Con damage, and died.
3) Same fighter as in 1, charged up to a lich while exploring the dungeon underneath the bloodmage's tower. Copped another harm for his trouble, failed his save, took 120 points of damage, and died. [This player actually said to me, before we started, how great it was that 3.5E harm could now kill on a failed save.]
4) Mage (same player as in 2, new PC because he got tired of always being a damage sink), got targeted by a dread wraith because he was the only one who was hurting it, got drained to 0 Con, and died.
5) Ranger cohort, got swallowed whole by a hungry spirit (based on No-Face from Spirited Away), tried to use a horn of blasting to blast his way out, detonated it instead, and died (but the resulting hole allowed the other trapped PC to escape).
6) Same mage as in 4, same battle as in 5. Got rolled over by a fiend of corruption (unique creature, sorta like a triple-HD gibbering mouther with extra powers), took 12 bite attacks, got reduced to ~-50 hit points, and died.
You don't need instakill effects for lethality, basically.
