I'll show you some of it, but you should really read through the documentation . It's linked at the bottom of every sheet. It explains in detail how these features work. This is not for Hunter's Mark, since I don't have a ranger build handy, but this shows one way to set up Sneak Attack for a rogue. Attachers are bits of code that add to an skill, attack, save and other features whenever they are invoked.I have this attacher set up to roll whenever an offensive power (an attack) is used: here is the code: {{text=[Sneak Attack](~repeating_classfeature_-kejkmevdzrcy69kwqeq_action) [Double Strike (Ability granted by Sickles)](~repeating_trait_-kul2q6dz1r3azvdqlgm_trait) [Sound Effect](!roll20AM --play|Dagger_01 by DM98362)}} It's basically adding the text field to the attack template and putting in some Ability Command Buttons. The first one is the only one that's important. [Sneak Attack] is the label of the button. (~repeating_classfeature_-kejkmevdzrcy69kwqeq_action) is the ability that is invoked when the button is pressed. The documentation explains how to find the name of the ability, but you could just as easily create an Ability on the Attributes and Abilities tab of the character journal and call it "Sneak-Attack" with a macro code of "plus [[3d6]] weapon damage". If you did this, the button becomes a little less arcane: [Sneak Attack](~Sneak-Attack) The output for the code I posted above looks like this, when I use a weapon attack: When I click the Sneak Attack button, I get the following output: Which is drawn from this ability on the character sheet (the one referenced by the ~repeating_classfeature_-kejkmevdzrcy69kwqeq_action code above: This approach is probably best since Hunters Mark and Divine Smite are conditional depending on attack. There are ways to get it to roll automatically, but you should be able to find examples in the documentation.
