Vulnerability vs. Weakness

[Zsig]

How does Vulnerability interacts with Weakened (or insubstancial for that matter)?

For example,

I use Turn Undead on some undead (vulnerable radiant 5) while I'm Weakened, do I:

-Calculate damage as normal, apply Weakened (1/2 damage) and finally add 5
-Calculate damage adding 5, and then divide the result by 2

??

Thanks in advance!

Vulnerability triggers when the target takes damage, not when the attacker deals damage, so it isn't halved.

I believe option 1 is correct, that is:

* Calculate damage, divide by 2 (weakened), then add 5 (vulnerability).

Hum, that's how we thought it would be, and that's how we're using it so far.

I guess I just wanted to be sure.

Thanks.

Hrm--then how should vulnerability interact with insubstantial?

Insubstantial reduces damage from attacks and ongoing damage. The extra damage from vulnerability is neither. Again, full vulnerability damage.
