This module is, in my mind, a must have. I personally like using multi-level builds a lot, and giving the player the ability to move between maps without DM input makes this much easier. The possibilities go beyond that. Want to create a teleport trap, link two outdoor maps, simulate a fall down a long shaft into another location? Maybe you want to create a confusing portal maze where players have to figure out the right combination of portals to leave. Portals makes it all possible, and better, automatic.

In this package, nothing has been done that you couldn't do yourself, but oh what a blessing it is not to have to do yourself. If you run games often, then you'll easily save enough time to warrant purchasing this module just during your players' character creation. The added signifiers to spells, such as range, whether they require concentration or not, makes it easier for players and GMs to keep combat flowing in-game, while the additional coding takes a load of work off the GM. In short, if you're a GM, you want this module. If you're a player, you want your GM to have this package. What are you waiting for?

In the spirit of full disclosure, I won this module. That being said, this was the third line on my Fantasy Grounds shopping list, just under the 5E PHB and DMG.
