I thought the hardening rules were a bit vague (what exactly is a source of stress?) and binary (you either roll and could get all of it, or you don't roll at all after you experience it five times). I also really like the way Unknown Armies does their hardening. So, I (more-or-less) converted it to Eclipse Phase, with as few changes as possible to the normal rules. Five sources of Stress: [list][*][b]Violence[/b]: Stress from hurting others, watching others get hurt, or getting hurt. Also fear of death. [*][b]Alien[/b]: Stress from the unknown, from inhumanity, from attacks upon your idea of how the universe works. [*][b]Isolation[/b]: Stress from being alone, from being separated from humans or society or sensory input. [*][b]Existential[/b]: Stress from attacks upon your sense of self, from guilt and self-loathing, from not being the person you think you are. [*][b]Helplessness[/b]: Stress from lack of control or safety, of powerlessness.[/list] [b]Hardening[/b]: Mental armor against its category of stress damage, reducing SV by one per point, to a minimum of zero. Every 3 in a single category reduces your maximum Moxie by one (so 2s across the board doesn't cause the reduction). Imposes quirks/personality shifts akin to derangements. Hardness usually ranges 1-10. Any stress that doesn't have a WIL × 3 Test does not apply Hardening. [b]Sensitivity[/b]: Reduces Trauma Threshold by one per point against its category of stress damage. Usually ranges from 1-5. Imposes quirks/personality shifts akin to derangements. [b]Taking Stress[/b]: Roll damage first, then apply Hardening. If the damage is completely soaked, that's it. If any damage remains, make a WIL × 3 Test (negative modifiers may apply for particularly horrific situations). Succeed, negate the remaining stress and get +1 appropriate Hardening. Fail and take the remaining damage as stress. If the failure is critical or severe, get +1 appropriate Sensitivity. [b]Healing Hardening and Sensitivity[/b]: Each point of Hardening takes 12 hours of psychotherapy to heal. Naturally, each point heals after 2 months with its type of stress and with a successful WIL × 2 Test. Each point of Sensitivity heals naturally and with psychotherapy as if were a disorder.
