I'm not familiar with the rules, dice rolls or the Attributes on the sheet, but here's an example using a 1d20 roll for the attack: &{template:default} [[[[{ceil([[1d20]]/@{selected|hth1_critical}),2}kl1]]*(?{Level|4}d4+2d4)]] {{name=Attack}} {{Attack Roll=$[[0]]}} {{Damage=$[[2]]}} So you'd need to replace the [[1d20]] bit with your attack roll, and possibly adapt it for one of the roll templates available in that character sheet.
