Thought that sanc and devotion don't stack?
I have never heard that. As far as I know, they do stack. Sanctuary cuts the damage down by 1/3, and then the devotion will cut that in half. Those two buffs alone would reduce 100 damage to 33 damage.
I'm fairly certain that the game checks order of operations from greatest to lowest. <Adhesive medical strip> would be checked first since it cuts <redacted> damage, which is the highest. Then sanctuary would check. Sanctuary would be doing less work though since the damage has already been greatly reduced.
As long as we agree that damage reduction from spell effects (i.e. buffs) is multiplicative (which anecdotal and experimental evidence seems to confirm), it doesn't matter which is checked first - the end result will be the same.
An example using commonly accepted values: if sanctuary (x) reduces damage by 33% and devotion (y) reduces damage by 50%, damage reduction (DR) for the two would be: DR = 1 - (x * y) or DR = 1 - (0.50 * 0.67)
DR = 0.665 or 66.5%
The result will be the same even if the reductions are calculated independently. If a lightning bolt does 100 damage (D) and that damage is reduced by devotion by 50% (100 * 0.50), the resulting damage is 50. If you then reduce the remaining 50 damage by an additional 33% for sanctuary (50 * 0.67), the result is the same as if you reduced the 100 damage by 33% and then reduced the remaining 67 damage by 50%.
In both cases the remaining damage would be 33.5. Or you could use the formula above and multiply D * DR - arriving once again at 33.5. We know several years ago that Dulrik changed how damage reduction is calculated, with damage reduction from spell effects (like sanctuary, devotion, protection) taking place BEFORE reduction from armor - it previously worked vice versa.
If armor reduction was multiplicative, it wouldn't have mattered. This leads me to believe that damage reduction from armor is value that is likely subtracted from damage rather than being multiplicative. Needless theorizing at this point, but fun if you're into that sort of stuff.
