It's such a relief to see LIFE use VIT instead. GRIT as damage prevention doesn't feel too far off from the concept of TEMP HP, but it definitely hurt a bit to have a Healer Aspect that didn't heal past one-time-use abilities, and that the "TEMP HP" you did gain would reset at the beginning of your turn every time, and was also pretty irrelevant if you wanted to use your powers outside of any interaction that wasn't specifically Strife.
