Symbol Spells

[Galtrug]

I've noticed some symbol spells (especially ones not from the core rulebook, such as symbol of strife or vulnerability) lack any indication as to whether they follow the symbol of death's "150 hp" rule. Reading it as written, that would seem to make them fairly underpowered for their cost and level, so I was curious as to whether that was the intent or simply some kind of oversight in the spell text?

Symbol of Death wrote:

When triggered, a symbol of death kills one or more creatures within 60 feet of the symbol (treat as a burst) whose combined total current hit points do not exceed 150. The symbol of death affects the closest creatures first, skipping creatures with too many hit points to affect.

Symbol of Strife wrote:

This spell functions as symbol of death, except all creatures within the radius of a symbol of strife are compelled to attack the nearest conscious creature for 1 round per caster level (similar to the “attack nearest creature” result of the confusion spell), even after leaving the symbol’s area of effect.

Instead of 'one or more creatures whos combined total current hit points do not exceed 150' it is 'all creatures'.

If you look at each of the symbol spells you will find the parts that conflict with the original (Symbol of Death). Those that conflict is the replacement wording.

Thanks, I was mostly thrown off by a few which were worded the same way but added a note that said there was no hit point limit.
