TEXT: IVERNICASTE	RISING	
  The	malevolent	greatsword	Ivernicaste,	Eternal	
  Winter	has	awoken	in	his	wintry	tomb.	At	the	
  start	of	the	adventure,	roll	initiative;	players	
  have	15	rounds	to	>ind	and	defeat	Ivernicaste	
  before	he	summons	an	apocalyptic	blizzard.	
  AREA	1:	DOORS	OF	THE	HEAVENS	
  • Three	massive	doors	are	set	into	the	frozen	
  mountainside	leading	into	Ivernicaste’s	tomb.	
  One	is	inscribed	with	a	star,	one	a	moon,	and	
  one	a	sun.	
  DEVELOPMENT	
  • The	doors	are	magical	and	locked	(all	lead	to	
  Area	2).	They	can	be	opened	with	a	DC	20	
  Strength	check	or	a	DC	23	Dexterity	check	by	
  a	character	pro>icient	in	thieves’	tools.	
  • Touching	the	sun	door	summons	an	
  indifferent	8ire	giant.	Touching	the	moon	
  door	summons	a	hostile	oni.	Touching	the	
  star	door	summons	a	friendly	young	copper	
  dragon	who	tries	to	summon	the	other	two	
  to	engage	in	a	philosophical	debate.	
  DRAMATIC	QUESTION	
  Can	the	characters	get	through	the	doors?	
  AREA	2:	CREVASSE	CHAMBER	
  • Multi-faceted	walls	of	ice	swirl	up	into	
  darkness.	The	glassy	>loor	provides	a	thin	
  layer	of	ice	over	a	deep	crevasse.	
  • A	tunnel	is	eighty	feet	away	across	the	room.	
  DEVELOPMENT	
  • A	hostile	air	elemental	swoops	from	above	
  to	harry	the	characters	when	they	enter.	
  • Any	character	walking	on	the	ice	must	pass	a	
  DC	16	Dexterity	check,	or	a	crack	forms.	If	
  three	or	more	cracks	form,	the	character	who	
  last	failed	must	pass	a	DC	16	Dexterity	save	
  or	fall	into	the	80-foot	deep	crevasse.	
  DRAMATIC	QUESTION	
  Can	the	group	cross	the	ice?	
  Treasure	
  A	frosty	Wand	of	Magic	Missiles	lies	at	the	
  bottom	of	the	crevasse.	
  AREA	3:	FALSE	SWORD	
  • A	short	>ire	giant	stands	behind	a	marble	
  pedestal	housing	a	serrated	greatsword.	
  Shattered	chains	of	iron	snake	around	the	
  >loor.	The	giant	shakes	her	head	and	smiles,	
  saying	she	has	already	defeated	Ivernicaste.	
  • A	large	hole	in	the	40-foot	high	ceiling	lets	in	
  blasts	of	wind	and	eddies	of	snow.	
  DEVELOPMENT	
  • The	Large-sized	>ire	giant	is	actually	a	hostile	
  oni	who	has	used	its	Change	Shape	ability.		
  • The	greatsword	is	the	oni’s	own	weapon,	a	
  false	duplicate	of	Ivernicaste.	
  DRAMATIC	QUESTION	
  Can	the	characters	defeat	the	oni?	
  AREA	4:	SNOWY	SUMMIT	
  • The	ice-rimed	greatsword	Ivernicaste	
  plunges	into	the	small	plateau	at	the	peak	of	
  the	mountain.	He	laughs	maniacally.		
  • A	howling	blizzard	whips	ice	through	the	air.	
  DRAMATIC	QUESTION	
  Can	the	characters	stop	Ivernicaste?	
  COMBAT	
  • Treat	Ivernicaste	as	an	ice	devil	with	17	AC,	
  150	HP,	and	a	>ly	speed	of	30	ft.	Replace	his	
  Bite,	Claws,	and	Tail	attack	with	a	Sword	
  Slash	attack	that	is	identical	to	Claws.		
  • Characters	in	the	blizzard	must	pass	a	DC	15	
  Constitution	save	at	the	start	of	their	turns	or	
  their	speed	is	halved	for	one	round.
