So I've actually had limited success with this in my game. I was able to do exactly what you said there, adding a "Crit damage" button to a single attack button, and it worked out really well. I was even able to embed choices into the crit roll for the type of damage that was crit (main hand damage, off hand damage, kick damage) and it worked just fine. The problem I ran into happened when I tried to add it to my existing attack roll buttons, which have a lot of options in them already. For example: /me attacks @{target|character_name}! /w gm ?{Flanking?|No,0|Yes,2} ?{Charge?|No,0|Yes,2} ?{Attack|Standard attack,Main hand attack:[[1d20cs>20+@{BAB}[BAB]+@{Str mod}[Str]+?{Flanking?&#125[flank]+?{Charge?&#125[charge]]] Damage:[[1d8+@{Str mod}]] Off hand attack:[[1d20cs>20+@{BAB}[BAB]+@{Str mod}[Str]-5[DW]+?{Flanking?&#125[flank]+?{Charge?&#125[charge]]] Damage:[[1d8+floor(@{Str mod}/2)]]|Full round,Main hand attacks: [[1d20cs>20+@{BAB}[BAB]+@{Str mod}[Str]-2[kick]+?{Flanking?&#125[flank]]]/[[1d20cs>20+@{BAB}[BAB]+@{Str mod}[BAB]-4[delay]-2[kick]+?{Flanking?&#125[flank]]] Damage: [[1d8+@{Str mod}]]/[[1d8+@{Str mod}]] Off hand attack: [[1d20cs>20+@{BAB}[BAB]+@{Str mod}[Str]-5[DW]-2[kick]+?{Flanking?&#125[flank]]] Damage: [[1d8+floor(@{Str mod}/2)]] Round kick: [[1d20cs>20+@{BAB}[BAB]+@{Str mod}[Str]-2[kick]+?{Flanking?&#125[flank]]] Damage: [[1d8+@{Str mod}]]|Opportunity,Attack: [[1d20cs>20+@{BAB}[BAB]+@{Str mod}[Str]+?{Flanking?&#125[flank]]] Damage: [[1d8+@{Str mod}]]|Standard w/ulak,%{Roslynd|UlakSA}|Full round w/ulak,%{Roslynd|UlakFR}|Opportunity w/ulak,%{Roslynd|UlakAoO}} I'd like to embed that button into each of the attack options so that it links to an individual crit damage button specific to this character, so she can choose crit damage for only the options she has. I currently settled for making a single macro for everyone's crit damage and it has all options visible for every player, plus my own option for enemy crits. I tried to add the embedded button to each option, even using alternate input codes, but it didn't work out. It gave text output to the entire macro (with the rolls in their correct boxes) and buttons for the attack options that aren't ulak options. The first button didn't function at all, but the other three buttons worked as they were supposed to. Any ideas?
