Let me first paint a picture. Our GM has a cool little rule: on a natural roll of 01, something spectacular happens. On a natural 100, something utterly horrible happens.
Well I rolled a 01 when getting my best craftsmanship sword Sanctified, so thus it became Anointed instead. It's Faith Power is that demons are -20 to parry/dodge. It does not yet have an appearance power. Cool! I still haven't used it though as I am a Noble Born Banisher Cleric who is better at talking and knowing stuff than shooting or stabbing. Our group is working for an Istvaanian Inquisitor. My cleric has already expressed his hesitancy for this kind of thinking, but being from the Drusian Chantry, I can be bent to her way of thinking with some creative RP. Also, we have not uncovered or even hinted at anything demon related, nor do I know if we will find any. I just like the idea of a Banisher.
After our most recent two session mission, I talked my GM into letting me roll to find a Lathe shield. That is the only way I could figure to make a shield invulnerable to being destroyed by a power field. I told him that if I found one, I wanted it to eventually become an anointed weapon as well, but the only Faith Power in the book that would apply to it would be the additional +15 to parry against demons. All the other Faith Powers are offensive in nature, not defensive. Well lo and behold, I rolled another 01.
So what I'm trying to come up with is something neat and characterful without being munchkin busted for their appearance powers. Again, my character is the primary social character along with some specific knowledge clusters. We are about to start Haarlock's Legacy, and I have no idea how much in the way demons will be present (please no spoilers!). I was thinking that the since the shield would have next to no use for an appearance power, would it be over the top to give the sword the 'Toxic' Appearance Power and have it usable against all demons/warpspawn? The drawback would be that if for whatever reason the weapons are separated, neither weapon has any Faith or Appearance power.
