Stacking of resists with shape change

[backwardsEric]

If I'm understanding things correctly, when @ has two resistance to an element from equipment or race and has one vulnerability to that element from equipment, the net result is no resistance to that element.

With the same combination of permanent effects (two resistances, one vulnerability) but where one of the resistances comes from a shape change, the net result is resistance to the element: the effects from equipment and race are combined (one resistance + one vulnerability = no resistance) and then the effects from the shape change are added (no resistance + resistance = resistance).

Was it intentional that the effects from a shape change stack that way?

There's little or no effect on current gameplay since pukel-man is the only shape that has a resistance (shards; its poison immunity would stack like any immunity does) and the standard items don't have anything that gives a vulnerability to that element.

I don't have a position, but what makes you say that a shapechange resistance is a permanent resistance?

What I meant was that it's not handled as one of the timed effects like a potion of poison resistance. So I probably should have said non-timed resistance or something like that.

IIRC I was just not very careful about that because I knew there were no gameplay implications. Probably it technically should be set up so that race, shape and equipment all have the same effect, but it's not a real high priority.
