Gah, so little time for D&D nowadays, but fulfilling my duties as a player is easier than fulfilling my duties as a DM, so here I am.
As a note, I had buffed my AC to 26 with Alter Self as detailed on my last IC post, and R5 rolled 25, so that should've been a miss I guess. I'll assume they had some ability to reduce my AC or something. I'll also take in account the fire damage I took didn't take in account my Fire Resistance 3.
Anyway, when R3 dies Morte will use an Immediate action to recover Scythe of Exorcism so she can use it again this turn, except this time I burn 45 ghost money to create a healing spirit in the square below R4.
Attack roll for Scythe of Exorcism. Crit threat range increased by 2 for a total of 18-20 crit threat.
Rolled 1d20+13 : 7 + 13, total 20
Damage roll:
Rolled 2d4+4 : 2, 4 + 4, total 10
