Is it possible to add the versatile option (holding two handed) to a monster's weapon damage stats?

If so what is the proper code/format?

I'd like to be able to roll the versatile option for the monster's in AboveVTT.

I'm unable to make the code below function...

Kanabo (War Club). Melee Weapon Attack: +2 to hit, reach 5 ft., one target. Hit: 4 (1d8) bludgeoning damage, or Hit: 5 (1d10) piercing damage if used with two hands to make a melee attack.

Yari. Melee or Ranged Weapon Attack: +2 to hit, reach 5 ft. or range 20 ft./60 ft., one target. Hit: 3 (1d6) piercing damage, or Hit: 4 (1d8) piercing damage if used with two hands to make a melee attack.

Could you copy-paste the Actions Description section into a post? That way we could examine it for possible coding errors (visible using the </> button in the post editor.)

Yari. Melee or Ranged Weapon Attack: [rollable]+2;{"diceNotation":"1d20+2","rollType":"to hit","rollAction":"Yari"}[/rollable] to hit, reach 5 ft. or range 20 ft./60 ft., one target. Hit: 3 [rollable](1d6);{"diceNotation":"1d6","rollType":"damage","rollAction":"Yari","rollDamageType":"piercing"}[/rollable] piercing damage, or Hit: 4 [rollable](1d8);{"diceNotation":"1d8,"rollType":"damage","rollAction":"Yari","rollDamageType":"piercing"}[/rollable] piercing damage if used with two hands to make a melee attack.

Kanabo (War Club). Melee Weapon Attack: [rollable]+2;{"diceNotation":"1d20+2","rollType":"to hit","rollAction":"Kanabo"}[/rollable] to hit, reach 5 ft., one target. Hit: 4 [rollable](1d8);{"diceNotation":"1d8","rollType":"damage","rollAction":"Kanabo","rollDamageType":"bludgeoning"}[/rollable] bludgeoning damage, or Hit: 5 [rollable](1d10);{"diceNotation":"1d10,"rollType":"damage","rollAction":"Yari","rollDamageType":"piercing"}[/rollable] piercing damage if used with two hands to make a melee attack.

Those are coded properly (except you have Yari in as the damage source instead of Kanabo for the two-handed damage). Your issue is not with DDB’s coding but with AboveVTT not reading it properly. You will have to contact the Devs that make that VTT.

This is why I hate attempting to play D&D online all that coding and crap, I feel for dude
