Fractional Defence Bonuses

Question

Some pieces of Armour can be granted a fractional DEF bonus. Examples can be seen on the example Adventure Sheet on page 16 of the rulebook.

As far as I can see, there are only three ways to obtain this (in Book 1 at least), i.e. Finer 0.2 DEF, Greater 0.4 DEF, and Superior Amour 0.6 DEF on the TA, TB, and TC Treasure tables.

How are partial DEF values treated? Do you

(a) Round; so 0.2 and 0.4 round to 0, while 0.6 and 0.8 round to 1.

(b) Truncate; so 0.2, 0.4, 0.6, and 0.8 all truncate to 0.

(c) Apply fractional damage, which might result in having 19.6 HP for example.

As written it seems you apply fractional damage, which is fine, but I would like to confirm if this is the case. Many Thanks.

You can stack DEF bonuses from different equipment parts. So if you have, let's say, two equipments 0.2, and one equipment 0.6, your total will be +1 DEF. If you have +1.8 DEF i would consider it as +1.

That's how i understood it.

@Martin Knight Could you confirm that the number is in fact truncated.

Thanks.

This appears to be treated differently to when shading in Damage Deflection since there a Shield can have 0.5 pips shaded.

Xavier's answer is correct and how def is applied.

Indeed, you can stack the fractional DEF bonuses, the example Adventure Sheet on page 16 does exactly that.

The issue isn't if you can stack them or not (and there's no reason to think you can't stack them), the question is what to do with the factional part of such a DEF bonus?

I can imagine most people will just round the number but some might round 1.8 up to 2. Rules as written, it suggests you should simply apply fractional HP as the rules tell you to subtract the DEF, so if you have a DEF of 1.8 you should therefore subtract 1.8, not 1 (or even 2).
