In which way "interesting"? I've always thought that was the correct spell's outcome. I mean isn't it supposed to give permanent + dmg and + HP? Otherwise it would be just rubbish.
It doesn't just give the extra stats, there is a condition label (bar under the abilities bar) which mention the increased stats. Dispel normally removes these conditions.
We will have to think this over in terms of should it be cleanseable versus updating the description.
Why? It is already permanent and it is already quite "expensive" in terms of what You need to sacrifice to make it work. Either you kill half your bg or severely damage your Shrine (with Graveyard, +45 Nora), just to possibly use that spell.
