Recently, I soloed my way through Path to the Paladin Queen's Forest (90 pages, at DriveThruRPG). This adventure is for Pathfinder 2.0 which I did use. To create my solo engine, I combined a yes/maybe/no oracle with Seeds of Decay (5e). Well, the PCs started the day off with some bad luck - they accidentally wandered into Queen Artemisia's hunting preserve. It was here that they ran into a cockatrice. When Salem the PC was petrified, Hannah freaked out and used alchemist's fire. It missed the monster's body, but a few drops did get on its beak. Its response was to run deep into the forest. When the forester showed up, he told them to leave, don't come back, and here are the directions to get to the Evergreen Forest. The PCs managed to get Salem back to town. A powerful caster just happened to be in town. He cast Stone to Flesh for a fee. The PCs spent the night at the inn. The next day (day # 2), they started walking in the direction of the Evergreen Forest. They were on a road with a canal next to it. This was when they were attacked by a Spore Zombie. The PCs killed it. Just before dusk, they set up a camp. When they looked for firewood they found an elven dagger. On day # 3 they entered the Evergreen Forest. They encountered a friendly wood elf who led them to the Wood Elf Village high up in the trees. The PCs had dinner there and spent the night there. On day # 4 they discovered footprints that led to a cave. In the Mushroom Chamber they solved the puzzle which gave them access to a hexmage's lab. They found several sick (cursed) fairies in glass jars. They freed the fairies and went through another door which took them into the hexmage's room. Grod did a spell duel with him. Grod won and the hexmage was killed. For loot they found a Potion of Necrotic Resistance. So, they continued to explore the forest. Next, they found Harry the Hermit. The PCs had a conversation with him and then moved on. They avoided a swarm of wasps and then found a portal. The PCs discussed their options and then entered the portal. I will continue this fun adventure on another day. :)
