The road to adventure is never an easy one. Whether travelling on horseback through lonely forest wildernesses, with a caravan across rolling planes, or by stalwart ship, danger awaits in the shape of escaped slaves, imprisoned mermaids, swarming elementals, blink bunnies, insane inventors, peeved trolls, possessed livestock, and a bevy of other hazards to block your way. By Land or by Sea, like the original En Route, is a collection of short encounters that GMs can easily insert into longer adventures of their own design, or use as transitions between published modules. En Route II features scenarios suitable to sea voyages as well as to land-bound travel, which can be played in about one hour's time. It promises to be just as useful and popular as the original!This sourcebook includes: A host of unique encounters designed to be played at a moment's notice New magic items, potions, weapons, spells, traps, monsters, and a cast of fully-statted NPCs ready to use out of the book Quick-reference appendices arranged by new D20 material, encounter location, and Encounter Level, to make finding encounters and crunchy bits fast and easy.
