Way to add a permanent effect for Fey Foundling

[srbongo]

Try

VULN: 1 cold iron

this works with the extensions I listed above.

For healing, you'd have to have two effects like someone said above, basically, but a custom effect on the Fey, then have the healer have an effect like

IFTAG (feyfoundling): HEAL 1

[tahl_liadon]

.
in additional to srbongo above, i've updated effects codes in my original post.

have fun!
