So, I avoided this when reviewing spells, because I figured that being a 4th level spell, it couldn't be the same thing as the 8th level spell. And I was right. The current spell is bizarre. It only allows you to target yourself, causing a large radius burst out from you, like bless. What it appears to do is entangle people in the area of effect. But to avoid entanglement requires a will save instead of a reflex save. Looking at the script, it also does something to the caster, but I'm not really sure what. Anyhow, I'll fix the spell to do what the SRD says, and move it to 8th level, because the current implementation is just weird.
