Just how and when can you use armor spikes? If you’re
using two weapons already, can you use armor spikes to
make a second off-hand attack? What if you’re using a
weapon and a shield? Can you use the armor spikes for an
off-hand attack and still get a shield bonus to Armor Class
from the shield? What if you use a two-handed weapon?
Can you wield the weapon in two hands and still make an
off-hand attack with the spikes? What are your options for
using armor spikes in a grapple? Can you use them when
pinned? If you have another light weapon, can you use that
and your armor spikes when grappling?
When you fight with more than one weapon, you gain an
extra attack. (Improved Two-Weapon Fighting and greater
Two-Weapon Fighting give you more attacks with the extra
weapon.) Armor spikes are a light weapon that can be used as
the extra weapon.
If you attack only with your armor spikes during your turn
(or use the armor spikes to make an attack of opportunity), you
use them just like a regular weapon. If you use the full attack
action, you can use armor spikes as either a primary light
weapon or as an off-hand light weapon, even if you’re using a
shield or using a two-handed weapon. In these latter two cases,
you’re assumed to be kicking or kneeing your foe with your
armor spikes.
Whenever you use armor spikes as an off-hand weapon,
you suffer all the penalties for attacking with two weapons (see
Table 8–10 in the Player’s Handbook). When using armor
spikes along with a two-handed weapon, it is usually best to
use the two-handed weapon as your primary attack and the
armor spikes as the off-hand weapon. You can use the armor
spikes as the primary weapon and the two-handed weapon as
the off-hand attack, but when you do so, you don’t get the
benefit of using a light weapon in your off hand.
You cannot, however, use your armor spikes to make a
second off-hand attack when you’re already fighting with two
weapons. If you have a weapon in both hands and armor spikes,
you can attack with the weapons in your hands (and not with
the armor spikes) or with one of the weapons in your hands and
the armor spikes (see the description of spiked armor in
Chapter 7 of the Player’s Handbook).
When grappling, you can damage your foe with your spikes
by making a regular grapple check (opposed by your foe’s
check). If you succeed, you deal piercing damage to your foe
(see Table 7–5 in the Player’s Handbook) rather than the
unarmed strike damage you’d normally deal when damaging
your foe with a grapple check. Since you can use armor spikes
as a light weapon, you can simply use them to attack your foe.
You suffer a –4 penalty on your attack roll when attacking with
a light weapon in a grapple (see page 156 in the Player’s
Handbook), but if your foe is bigger or stronger than you, this
might prove a better tactic than trying to deal damage through a
grapple check because there is no opposed roll to make—you
just have to hit your opponent’s Armor Class. You can’t attack
with two weapons when grappling, even when one of those
weapons is armor spikes (see the section on grappling in
Chapter 8 of the Player’s Handbook).
You can’t attack and damage your foe if he has you pinned.
If you break the pin and avoid being pinned again, you can go
back to attacking your foe. If your attack bonus is high enough
to allow multiple attacks, you might break the pin and then use
your remaining attack to damage your foe. To accomplish this,
you must first use an attack to break the pin. You can break a
pin using the Escape Artist skill, but trying to do so is a
standard action for you; once you use the standard action to
attempt escape, you can’t make any more attacks during your
turn.
