Characters were created by deriving rules from the Beyond the Wall system. Character concepts come from two personae in an early 1990s AD&D 2e campaign.
Overlaid onto a majority of BTW's rules are the following house rules:
- Fortune Points
- these points are restored after a Long Rest
- sacrifice a FP to re-roll a failed saving throw
- sacrifice a FP to re-roll a failed attack roll
- sacrifice a FP to re-roll critical damage before doubling
- sacrifice a FP to re-roll a failed ability check
- sacrifice a FP to cry out to Cromm for healing (2d6)
- sacrifice a FP to give an ally either a re-roll or advantage on next roll
- Leveling
- Character Advancement is unlimited in levels
- Every five levels, increase one stat by one point
- after level 10, you only gain Con bonus to HP
- Dorn & Exie gain in FGT/THF when leveling
- Zorvin will gain in CLE/WIZ when leveling
- PCs use the better saving throw vs each type of save
- FGT/THF gains 7+Con bonus HP upon leveling
- CLE/WIZ gains 5+ Con bonus HP upon leveling
- FGT/THF gain a Warrior Knack at levels 1, 3, 6, and 9
- Undead
- Levels aren't permanent drained by powerful undead
- restore one level whenever you:
- get (a) full day of rest and (b) a remove curse
- restore one level whenever you:
- Levels aren't permanent drained by powerful undead
