A very solid introduction to what looks like an ongoing series set in the same town with recurring npcs (I've played through the second book (The Shadow of Serpentridge Hollow) too and was very happy to meet them again). I played as a 1st level high elven fighter and my dice were kind in the combat encounters so I survived unscathed. You have the ability to gain a decent amount of coin which helps set your character up with any extra equipment for the next book which has a lot more in it. It's definitely well worth the very reasonable price and I'm interested to see what futher adventures the author has planned.

Please do not let my comments minimize what I think is a good solid, but brief solo adventure.

Areas where modifications are required... 1) Stated as levels 1-3 but no adjustment is provided for which level is to be run. I'm running a 2nd level 1/1 Sorlock and had to adjust the encounters to 1 Goblin Boss with 2 Goblins as Gate Guards outside and a Goblin Shaman with 2 Goblins as bodyguards inside for proper game ballance. This gives 2 each 300xp encounters, increasing my character from 2nd to 3rd level. 2) The word Ogre is used 3 times, but there is no Ogre encounter 3) No treasure, just the 150gp reward and a Potion of Healing from the townsfolk... what happened to the 50gp collected by the Goblins every time they blow the silver horn? I recommend 1 gp per 2 xp in treasure or magic item value awarded so that this would be 125 gp in the Goblins posession, plus the reward offered by the townsfolk. 4) Need a map for the Goblin Gate/Barricade as this could be a combat situation. My first instinct would to be pay the 50gp to gain entry then negotiate via combat.

I like this adventure with the above modifications... it very nicely satisfies my requirements for character development.

Follow-up @ item 2) above: I'm a power gamer so standard DMG recommendations are not very challenging... > Playing a Yuan-ti 2nd lvl @ 1 lvl Stone Sorcerer > 1st lvl Hexblade Warlock with 16 Con & 16 Dex & 16 Cha, all +3 modifiers, using a standard 27 pt build gives you 19 AC > 21 AC using a shield, immunity to poison, advantage on all magic saving throws, a Familiar that only uses the Help action so you have advantage on one skill roll or attack roll per round, always using two weapon fighting when hand-to-hand, plus 3 Sleep/Shield/Hex spells > Sleep spell takes out the Goblin Boss > Hex/Eldritch Blast takes out the 2 Goblins as Gate Guards outside > you'll take a hit or two, but Healing Surge and you're back up to full hit points > Sleep spell takes out the 2 Goblins as bodyguards inside > maybe you'll take a hit or two before they drop > Hex (still concentrating)/Two weapon fighting (shortswords) takes out the Goblin Shaman > So, you've used up all your spells, except for Cantrips and are still concentrating on Hex and you're at least 1/2 dead > Perfect game balance!

At first I was undecided as to whether this needed a DM or not, but it works well without. I liked the blocked text. This was a nice little adventure.
