0.8.1 DV versus PV
As everyone knows from reading the ADOM Manual, DV is an abbreviation
for Defensive Value and PV is an abbreviation for Protection Value.
The former determines how hard it is for an opponent to hit the PC;
the latter determines how much damage is absorbed by a PC's armor if
a monster makes a successful hit. In recent gammas of ADOM, there
has been a tendency for monsters to score more critical hits which
bypass PV. Some monsters *always* bypass PV, notably claw bugs,
which make them very annoying opponents for low level characters.
Note also that non-artifact armor can be damaged by monster attacks,
lowering its Protection Value especially and eventually destroying it.
So the question arises, which is better, a high DV or a high PV?
As with the question of whether to specialize in one weapon or become
proficient with many weapons, it is largely a matter of personal
preference and style. There are successful players who use both
approaches. In practice, it is possible to raise DV to the point
where none other than the very highest level monsters can hit the PC.
A DV over 100 means very few monsters will hit the PC successfully.
However, a DV this high is not available to any but the very high
level characters that specifically pursue it. Likewise, a PV over
100 means few monsters can hurt the PC, since the vast majority do
not deal over 100 points of damage in one round. Bear in mind,
however: 1) the possibility of critical hits and 2) the possibility
of running into something very nasty, such as balors, Greater Molochs
and the Emperor Moloch which certainly *do* deal over 100 points of
damage per round.
A general rule of thumb? Add up the DV and PV bonuses. A [-3, +5]
iron chain mail is about as good as a [+0, +2] leather armor (and the
latter is lighter and won't rust). Few non-artifact armors can compete
with an average eternium plate mail at [-1, +13]. Dragon scale mails
averaging [-2, +11] are also extremely desirable armors since they
grant immunity to the element corresponding to the dragon the armor is
derived from. On the DV side, few non-artifact items can compare to
eternium tower shields averaging [+16, +6]. Dragon scale mails and
eternium tower shields are so powerful that many players will use a
wish on these items.
The debate over DV versus PV is one that will never be settled, which
is as it should be. ;-)
0.8.2 DV bonuses
DV is increased based on Dexterity twice, by (Dx-12)/2 and (Dx-9)/2;
being Drunk decreases DV by 3. High Alertness with Alchemy have also
positive effect on DV (see section 0.4).
Monks get DV increased by (Level*2)/3 if not wearing armor except
specific (blood-stained robe, armor of rage?); Beastfighters by Level/3.
Mindcrafter's Mental Shield provides (Level+Wi)/5. PC's recieve about
half DV bonus from unarmed combat when fighting with staves.
0.8.3 PV bonuses
PV is increased based on Toughness, by (To-18)/2 (max 20), being
Blessed increases PV by 1, Mincrafter's Mental Shield provides
(Level+Wi)/8. If a PC's PV is below 4, they will suffer corresponding
damage from kicking walls and statues.
