Note the less critical strike chance modifier will affect effects that override base critical strike chance like Trypanon, but effects that always causes a crit such as in Lightning Tendrils and Plume of Pursuit won't be, therefore negating the item's downsides. Actum also does not receive less critical strike chance. The breakeven point in critical strike multiplier for a character to match the increased damage grated by Marylene's Fallacy alone at an equal critical strike chance is at a critical strike multiplier of 274% (150% base + 124% additional critical strike multiplier).
