Hi Raul! I've been running a game for about 6 weeks using 4e. I'm using the Character Sheet by Wes, with power macros built via this tool: <a href="http://4e-power-builder.s3-website-us-east-1.amazonaws.com/" rel="nofollow">http://4e-power-builder.s3-website-us-east-1.amazonaws.com/</a> I haven't found any API scripts to use with 4e yet, but I'm looking. Here are my macros: These macros are built using the information on the following page: <a href="https://wiki.roll20.net/DnD4e_Character_Sheet" rel="nofollow">https://wiki.roll20.net/DnD4e_Character_Sheet</a> They’re built with guidance from this page: <a href="https://wiki.roll20.net/Dungeons_and_Dragons_4th_Edition" rel="nofollow">https://wiki.roll20.net/Dungeons_and_Dragons_4th_Edition</a> Some of the values are based on character sheet values, except for all of the Atk variants and Init, which are values I manually added onto monster character sheets. The request defenses will work without manually adding values. Just make sure to assign a token to a sheet, then after clicking on the macro, click on the target token and it will display defenses. Monster actions I changed all the attacks to have damage removed. I also replaced /emas with /w gm So no one could see my prep. Attack-ac /emas @{selected|token_name} rolls [[1d20+@{selected|Atk}]] to hit vs @{target|token_name}'s Armor Class [[@{target|ac}]] and deals [[@{selected|Dmg}]] damage. Attack-fort /emas @{selected|token_name} rolls [[1d20+@{selected|Atkf}]] to hit vs @{target|token_name}'s Fortitude [[@{target|fort}]] and deals [[@{selected|Dmg}]] damage. Attack-ref /emas @{selected|token_name} rolls [[1d20+@{selected|Atkr}]] to hit vs @{target|token_name}'s Reflex [[@{target|ref}]] and deals [[@{selected|Dmg}]] damage. Attack-will /emas @{selected|token_name} rolls [[1d20+@{selected|Atkw}]] to hit vs @{target|token_name}'s Will [[@{target|will}]] and deals [[@{selected|Dmg}]] damage. Monster-Initiative /emas @{selected|token_name} rolls [[1d20+@{selected|Init} &{tracker}]] Monster-damage /emas @{selected|token_name} rolls [[@{selected|Dmg}]] Request-defenses /emas The Dungeon Master checks @{target|token_name} defenses: Fortitude [[@{target|fort}]] Reflex [[@{target|ref}]] Will [[@{target|will}]] and Armor Class [[@{target|ac}]] Saving-throw [[1d20cs>[[10 - (?{Bonus|0}) ]]cf<[[ 9 - (?{Bonus|0}) ]] + (?{Bonus|0})]] All of my adventures have been custom so far. I've been adding monsters as needed, but I really wish I had an API script that could import old DDI monster files from the Adventure Tools or elsewhere. If anyone has any suggestions, I'd be glad to hear them.
