A Final Twilight event as a result of extended Warping for Magi is potentially how their lives as characters will end, although to be fair many Magi in my experience are retired by story events, killed, or paused due to a permanent hiatus of the game. In my view warping is something which infrequently impacts a Magus character and very rarely ends their life through Final Twilight.
When advancing a character through their years post-gauntlet in bulk there is a rough rule of thumb to add a few warping points each year due to longevity, strange events and spell casting botches. Two points per year is ok, but does not reflect virtues and flaws, or other game events.
So how many points are reasonable to add per year when advancing a character before play begins?
Here are my suggestion:
- Add 1 point per year the character has a Longevity Ritual. This is standard to the core rules.
- Add 1 point for each extra virtue or flaw gained though non-Twilight related means (cult initiation, realm of magic, freaky story event in accelerated advancement, etc).
- Add 1 point per 5 years (rounding down) if the character has a flaw which makes Twilight more regular or more severe. If the character has more than one of these flaws then they are cumulative.
- Add 5 points per 10 years after their Gauntlet; because things go wrong.
- Mitigate the total value of item 4 above by subtracting the Familiar’s Golden Bond score; because the cord should greatly reduce the probability of botching.
- Further mitigate item 4 if the character has a suitable virtue such as Cautious Sorcerer, reducing by -1 for each.
Hope this is useful.
