This product like Robs other products has been painstakingly created with superb detail. As a DM and being able to drag and drop effects and having the desciption symbols as part of the name. This makes things so easy for me and my players to see whats going on without looking things up or editing stuff on the fly. If the module that its linked to ever changes be sure Rob will have an update shortly after. I have purchased his 2016, and 2017 packages along with all the effects for 2018 and have been truely greatful for the ease of use and attention to detail and the consistant updates.
If your a new DM or a veteran DM this will make your experience easier and in my opinion more enjoyable for you and your players.
