It's a shame i just did a cleaning up last week and deleted everything but here's from memory :
I modified it quite a bit, since we where playing in FR..
A timely rescue : doubled the map by copying, mirroring, and pasting them together - put the foes on the left, and heroes entering on the right - added many bystanders in the way
village showdown : same map
changed foes to : 6 banite converts, HalfOrc Scarthane
blades in the night : same map
changed foes to : 2 doppelgangers and 4 barghest savager
Black march, white water : ditched this part (no river boat travel) - they travelled between 5-6 towns before finding a feywild crossing in a cavern (to get to the Pillars of Night)
hunter and hunted : changed map,
changed foes to : 3 young phase spiders, 9 phase spider hatchlings and 9 spiderlings
fire on the water : changed map,
changed foes to : 2 HobG Archers, 6 banite converts, HobG warcaster
the friend of my enemy (where they found my feywild crossing): changed map
changed foes to : mourning haunt (upgraded to lv4), 5 manes
Hall of warriors (hall of faith): changed location to T3 instead
changed foes to : Tajani (solo from friend of my enemy) , Level 3 Poison Trap in small firepit (expanding each round), and Level4 Demon Face trap on door (pushes them back inside the room, hard to leave)
(hall of warriors, now empty)
black cells : same map
changed foes to : Thagdal (from LFR adventure SPEC1-1, encounter 10) , spectral tendrils (all difficult terrain are tendrils) , arcance energy pools (both pools at each end)
last stand : same map
changed foes to : only 3 berserkers, no other foes
wrath of naraash : same map
changed foes to : Jaryn (same) , Naarash is now a Chained Cambion, 3 Infernal Battle Armor and Hand of Bane Lv5 hazard (Eye of Naarash)
Thematically, i think the Cambion (chained devil) is better suited than a Balgurra (brute demon).
