is there an event\damage in game session log ??

after recognizing a potential bug on thornmail ( due errata incremental calculation of % on yellow parenthesized buffer on item description(draw by pointeroveritemicon after bought ) i need a reference about the exact damage deal
after bought ninja shooes + thornmail (so bonus armor should be 30 ) the parenthesized value was 24 so the damage should be (30 +25) *(100/[100+MR])
