Why. PrismScroll Djinn is the ultimate on-demand D&D resource. Make a request, for example "Fireball", and have the Djinn pop up all the information you need about that particular query, the damage, the range, you name it! With over +300 spells and 100+ game rules from the SRD, you will have all the magical information need at your beck and call. Features. Press-To-Talk. There are two ways you can ask for the Djinn's help. You can either use the press to talk feature for short and quick requests or you can use the play/stop setting which will be on the look out for keywords as long as you want it to listen. Favorite Lists. If you have a particular set of items that you always reference, you can create up to 7 saved lists for easy and quick reference. Compendium. If you want to search for an item yourself, you can use the compendium feature, allowing for text search. Keyword adjustments. Some words in the Dungeons and Dragons realm are unfortunately not immediately recognizable by the Djinn. No need to worry! You can help the Djinn by adding keywords to search items based on how you say/pronounce a particular word. Equipment, Magic Items, Monsters, Eldritch Invocations, and More. All spells and game rules will be free for all users! If you want the Djinn to be able to bring up more information, there are 4 additional categories that you can purchase with over 700 additional items. All items you would receive can be seen in the compendium even if they are locked so you can see what you would be getting. Join Us! Make your wish and try PrismDjinn for free in your next session!
