I have read over the wiki for the modifiers (<a href="https://wiki.roll20.net/D%26D_5E_by_Roll20" rel="nofollow">https://wiki.roll20.net/D%26D_5E_by_Roll20</a>) and have most of what I want in place. However, I am trying to create a weapon for one of my players that on a Critical hit, it does an electrical discharge (long story short - he is building is own Mage Staff).&nbsp; So, this is what I have: Item Type: Weapon, Damage: 1d8, Damage Type: bludgeoning, Melee Attacks +2, Melee Damage +2, Secondary Damage: 1d8, Secondary Damage Type: lightning, Secondary Damage Critical: 1d8!&gt;6, Spell Attack +2, AC +1 However, the Critical does not work (which then in turn causes the Melee damage to not work correctly, because I have bad syntax). What I would really like is the Secondary Damage to be 0 (which that is pretty obvious how to do), but the Critical damage be exploding (which would be the wild magic surge from experimental creation) Any help with this would be appreciated.&nbsp;
