Elemental Adept FEAT

[antaskidayo]

how do you code a weapon or a spell that can overcome an enemy's resistance?

[Zacchaeus]

Add the 'magic' tag to the damage line. More information here (https://www.fantasygrounds.com/wiki/index.php/5E_Item_Sheet).

EDIT: Looking again at the title of your post (rather than just reading the question) and then reading the Feat; that gets a bit more complicated. Easy enough for weapons since usually there's something about the resistance being overcome by magic weapons in the description of the resistance. However for spell damage there's no such thing. There's probably two ways. You could add the effect VULN: <damage type> to the NPC which would negate the resistance or the DM could temporarily switch off the effect on the CT before the spell is cast. Oh, and no way to do automate the rolling a 1 and making it a 2. You'll just need to add that in manually.

What if you made a weapon entry for the spell and gave it the property Reroll 1?

[Bidmaron]

Reroll 1 is much more powerful than 1=2

[Nickademus]

True. Didn't think through that one very well. Distracted by coding.
