adjust "ability change damage" not working

[tahltwo]

.
hi.

i am trying to custom build a slam attk that does 1d3 wis damage.

i have under bestiary monster creation > background >
- natural attack: slam 6d6
- special attack: ability drain - wis (slam)

then under "adjust" tab, the "ability change damage" looks promising, and seems to want to do what i need. however, it doesn't seem to do anything:

- ability change damage: "ability drain - wis" and 1d3 set for damage.

help?

thanks,

...also in adjust:

- remove class skill: what does this do? both skill tab and statblock still shows skill selected to be removed.

anyone?

Remove class skill removes he +3 and class skill status of a given skill, doesn't remove the skill completely.

I'm trying to do something similar with a slam attach, I am trying to add it a Natural attack but that might not be appropriate so I am also looking for some guidance on that as well.

ACTIONS
Multiattack. The monster makes two slam attacks.

Slam. +8 to hit, reach 5 ft., one target. Hit: 7 (1d8 + 3) damage plus 28 (8d6) fire damage.

I can add a natural slam attach but I cant seem to add the fire damage as well. Also is the Natural Attach the right place to put this?
