The result for 171+ on the Shock Table 8-11 on page 288 is changed to what it was in DH1:

“The character is so affected that he begins to see strange and terrible visions as his hold on reality shatters. The character suffers the effects of "acute hallucinations" – either peculiar to that PC or roll on the Hallucination Table on page 147 – for 2d10 Rounds. After the hallucinations fade, the character will make all Tests with a -20 penalty while the encounter lasts.

The character gains 2d10 Insanity Points & 1d10 points of permanent Willpower damage."
