@Daryl: what GiGs said ;). I usually try to avoid html replacements whenever possible, though it's sometimes a necessary evil if you really want a particular functionality. Another thing to keep in mind when you use the Adv query for --saveFormula is that whatever you choose will be applied to ALL the tokens in the area. So, if one creature has circumstantial DisAdv and the rest don't, you would probably need to use a "Trigger-Target" on all of them. Or if there are a ton of tokens, perhaps temporarily move the outlier token out of the AoE, "Trigger-ALL", then move it back into the area and Trigger-Target with DisAdv. That's all a bit fiddly for me, which is why I have just used the vanilla 5eINT so far in my games. Again, it comes down to how frequent these cases come up in your own game to determine what works best for you. @Leon: So, nothing happens and you get no error messages? Do any of your macros using other api scripts work?
