I cannot tell you how to do 3 boxes, it would require the Roll20 Devs to change the sheet. But, you can make an Ability macro for it using the same output format as normal. Here is how you do that: 1) Edit your bow, add Elven Accuracy to the description box. (This will be deleted later, or you can put some other text in to indicate this is an Elven Accuracy attack.) 2) Make an attack with your bow. (You can now remove the Elven Accuracy line from your bow.) 3) Go to the chat window, click on it, push the up arrow, then copy the text. The text should look similar to this: @{Merric|wtype}&{template:atkdmg} {{mod=+5}} {{rname=Shortbow (2hand)}} {{ r1=[[@{Merric|d20}cs>20 + 3[DEX] + 2[PROF]]]}} @{Merric|rtype}cs>20 + 3[DEX] + 2[PROF]]]}} {{attack=1}} {{range=80/320'}} {{damage=1}} {{dmg1flag=1}} {{dmg1=[[1d6 + 3[DEX]]]}} {{dmg1type=Piercing}} 0 {{dmg2=[[0]]}} {{dmg2type=}} {{crit1=[[1d6[CRIT]]]}} {{crit2=[[0[CRIT]]]}} 0 {{desc=}} {{spelllevel=}} {{innate=}} {{globalattack=@{Merric|global_attack_mod}}} {{globaldamage=[[0]]}} {{globaldamagecrit=[[0]]}} {{globaldamagetype=@{Merric|global_damage_mod_type}}} ammo= @{Merric|charname_output} 4) Now create an Ability (Attributes and Abilities tab), paste the text you got from copying and pasting. Now, we change the bolded section above to this (make sure you use the correct name, not "Merric") r1=[[ {@{Merric|d20}cs>20, @{Merric|d20}cs>20}kh1 How it looks: @{Merric|wtype}&{template:atkdmg} {{mod=+5}} {{rname=Shortbow (2hand)}} {{ r1=[[{@{Merric|d20}cs>20, @{Merric|d20}cs>20}kh1 + 3[DEX] + 2[PROF]]]}} @{Merric|rtype}cs>20 + 3[DEX] + 2[PROF]]]}} {{attack=1}} {{range=80/320'}} {{damage=1}} {{dmg1flag=1}} {{dmg1=[[1d6 + 3[DEX]]]}} {{dmg1type=Piercing}} 0 {{dmg2=[[0]]}} {{dmg2type=}} {{crit1=[[1d6[CRIT]]]}} {{crit2=[[0[CRIT]]]}} 0 {{desc=}} {{spelllevel=}} {{innate=}} {{globalattack=@{Merric|global_attack_mod}}} {{globaldamage=[[0]]}} {{globaldamagecrit=[[0]]}} {{globaldamagetype=@{Merric|global_damage_mod_type}}} ammo= @{Merric|charname_output} Close it and now you have a macro that does it for you. Limitation: The Macro will ALWAYS roll 2d20 and keep the highest one, but when you have advantage turned on AND you want Elven Accuracy it will work correctly. When not using Advantage make the roll normally (not via this Ability macro). You may be wondering about the logic of it. This basically moves advantage to the 2d20kh1, and the "advantage" roll you normally see is the 3rd d20 that replaces the lowest die of the 2d20kh1. Edit: added the Elven Accuracy description to the steps.
