Hello, I've moved an offline Werewolf The Apocalypse game online using Roll20 . I've not used Roll20 before. In my game, the house rules for dice rolls differ from those used in the WtA character sheet: on a standard roll, difficulties vary from 1 to 10; all 10s explode; and 1s cancel successes. To recreate this, I've written some macros for attacks and skill checks. And I have two questions about how they can be streamlined. Default option values The macro for a basic roll is: /me rolls [[(?{Dice pool}+?{Extra actions?|None,0|One,-1|Two,-2|Three,-3|Four,-4|Five,-5|Six,-6}+?{Other modifier})d10>?{Difficulty|6,6|1,1|2,2|3,3|4,4|5,5|7,7|8,8|9,9|10,10}f1!]] successes If no value is entered for "Other modifier”, the macro stops running and no roll is made. Is it possible to give this a default value of "0", without creating a drop-down menu? Difficulty modifiers The other question is about macros with pre-set difficulties, like this one for changing werewolf forms: @{selected|token_name} tries to change form, and gets [[(@{selected|Stamina}+@{selected|Primal-Urge}+?{Extra actions?|None,0|One,-1|Two,-2|Three,-3|Four,-4|Five,-5|Six,-6}+?{Other modifier})d10>?{Form|Homid,6|Glabro,7|Crinos,6|Hispo,7|Lupus,6}f1!]] successes While the difficulties for changing forms are set at 6 and 7, occasionally these can drop by 1. I don’t want a very long menu of difficulty settings, so I would like to have an “other modifier” option as in the previous macro to tweak difficulties. But when I try to add a “+?{Other modifier}” to the difficulty – (?{Form|Homid,6|Glabro,7|Crinos,6|Hispo,7|Lupus,6}+?{Other modifier}) – the macro rolls, but gets 30-40 successes. If there is no math operator before the “d10>” then using “+?{Other modifier}” in the difficulty setting works as I intended. So is it possible to add an maths operation to the difficulty part of the macro and in the dice pool part? Thanks. - Richard
