Strike

Roll 1 twenty-sided die. Add +9. Compared against AC 15: you hit if the kept d20 face plus the bonus totals 15 or more (so the d20 needs to land on at least 6). A natural 20 always crits, regardless of AC. On a hit, deal 1 8-sided die (slashing damage), plus 1 6-sided die (fire damage). On a crit, double the damage dice (the 1d8:slashing+1d6:fire becomes 2d8:slashing+2d6:fire); flat modifiers stay the same. The target also has type-specific damage reduction (DR 3 vs slashing). Each typed bucket of the base damage is reduced by its own value and clamped at 0 before the buckets are summed and before any flat DR applies; untyped damage components are unaffected.
