The setting is good. Getting to the spire itself is an interesting task and the scenario offers various ways to accomplish it, as well as offering some enemies to make it harder. Once it gets to the actual, titular spire, it's still... alright. There are some interesting magical things to play with but the dungeon part lacks the feeling of urgency. The designer foresees some tricky situations and explains how to deal with them, which is what all scenarios should do.
