This invisibility potion is quite powerful - it can last for hours. However, it only works while the user has their eyes closed. For those that do not require open eyes to see, it simply does not work. Go to Comment
This potion allows the user to walk on water, carrying as much weight as they could normally handle. However, it is like walking on a waterbed, and should any part of the walker touch the water, aside from their feet, the effect immediately ceases. Go to Comment
Yes, these items are generally one-off constructions. They are very expensive (that is why the target in the backstory was a king) and need suprise to be effective. Once mages know what to look for, these suits lose their effectiveness. Go to Comment
In any case, I would let the GM decide on how well they are known. Their power is increased by their rarity. In this case, only Kagerith knows the way to make these suits (he has apprentices, but he is jealous of his secrets, so they only know part of the process). If his written works were stolen, then other mages could carry on with production. Go to Comment
Jeesh, the feedback others make to put a little more detail into the Bolt of Twilight has created a monster! :)
Seriously, when I started to read the description, I was wondering why people ever worship these things but that became pretty clear early on. This is an excellent alternative to the generic evil gods of death.
A people who believe it is incredibly impolite to speak to anybody they meet for the first time. They believe their actions should speak for them until they are comfortable in each others presence and can then trust each other. Only then would converstation be appropriate.
