Code:
if (field[hIsOn1].value <> 0) then
hero.child[aCON].field[Penalty].value -= field[hUsed].value
endif
if (field[hIsOn2].value <> 0) then
hero.child[aCON].field[Penalty].value -= field[hUsed].value
endif
There's no way to have separate selectors for these, so the primary and secondary damage will be the same, which doesn't match the way the item works.
Also, is the person who owns the poison item going to be the one who's going to suffer the damage from it? Or do you have to pay 4500gp and then suffer these effects? (just joking - you'd buy it for free).
I'd recommend just making poison items normal pieces of gear, with no activation, and leave it up to the victim to use adjustments to apply the effects.
Either that, or add a separate adjustment for the effects, rather than putting the effects on the gear - but there, you have the same problem that there's only one incrementer available. I still recommend using the normal adjustments to apply the effects of poison.
