Hi Jose, and welcome! I think I remember you from the old forum.
I love this spell, this is brilliant. Rope Trick was always one of my favorite DnD spells from the old days, despite rarely being used. It is exactly the type of spell that fits with Codex Superno. I like how you wrote it just like the Superno style as well.
Like the best spells in that book, this one has ‘adventure hook’ written all over it. I can see this dovetailing into any number of scenarios.
Thanks for posting this. If you have time, I’d love to hear something about what kind of gaming you do or what kind of campaign you run.
