A mercurius (plural mercurii) is a shifting, ooze-like
blob made from silvery metallic fluid. Mercurii are
native to planes where intelligent machines dwell,
such as the Inevitables. They digest metal and are
especially attracted to magical metals, meaning that
these constructs are wary of them. They are typically
trained to be guardians or hunters.
Mercurii move with blinding speed; they race along
vertical surfaces as easily as horizontal ones.
Absorb (Su): A mercurius that snatches a magical item
(other than one made from stone) can absorb it, draining
its enchantment and disintegrating its substance. On
each round on which the mercurius holds the item, the
item is dealt 19 points of acid damage; on reaching zero
hit points, it is absorbed. When a mercurius absorbs
an item, it gains ten temporary hit points, irrespective
of the item’s magical strength. Artefacts cannot be
absorbed.
Acid (Ex): The metallic blob secretes a digestive acid that
dissolves organic material and metal quickly but does
not affect stone. Any melee hit deals acid damage; the
opponent’s armour and clothing immediately dissolve
and become useless unless they succeed on Reflex
saving throws (DC 19). A metal or wooden weapon
that strikes a mercurius also dissolves immediately
unless it succeeds on a Reflex saving throw (DC 19).
The saving throw DCs are Constitution-based. The
mercurius’ acidic touch deals 19 points of damage per
round to wooden or metal objects, but the creature must
remain in contact with the object for one full round to
deal this damage.
Constrict (Ex): With a successful grapple check, the
silver tentacle of a mercurius constricts for 2d4+11
damage plus 2d6 acid damage.
Disarm (Ex): Mercurii are adept at snatching objects.
They receive a +2 racial bonus to their attack rolls when
making a disarm attempt.
Engulf: A mercurius can dart forth swiftly and envelop
a foe in its gleaming mass. It cannot make a slam attack
during a round in which it engulfs. The mercurius
merely has to move over the opponents, affecting as
many as it can cover. Opponents can make attacks of
opportunity against the mercurius but if they do so they
are not entitled to saving throws. Those who do not
attempt attacks of opportunity must succeed on Reflex
saves (DC 28) or be engulfed; on a success, they are
pushed back or aside (opponent’s choice) as the blob
moves forward. Engulfed creatures are subject to
the mercurius’ acid damage and are considered to be
grappled and trapped within its body. The saving throw
DC is Strength-based.
Improved Grab: To use this ability, a mercurius must
hit with its slam attack. It can then attempt to start a
grapple as a free action without provoking an attack of
opportunity. If it wins the grapple check, it establishes
a hold and can constrict.
Magic Reflection (Su): The mercurius’ gleaming form
reflects all rays, lines, cones and magic missiles. There
is a 30% chance that any such spell is reflected back at
the caster; otherwise it is simply negated.
Rainbow Pattern (Sp): The mercurius can generate
a rainbow pattern around itself at will as a standard
action, as per the spell, with a Will saving throw (DC
19) allowed to resist the effect. The mercurius cannot
maintain the pattern and move. If it moves, the effect is
broken. The save DC is Constitution-based.
12. The Repository of Tomes
This room contains three circular tables of white marble
veined with blue, around which are chairs made from
wrought iron. Against the walls stand bookcases of
strange dark wood, with glass panels in the front that
show the closely packed volumes within.
The bookcases are made from ironwood, the most
practical substance to protect the books from wet ice.
There are six cases in total, each one locked (Open Lock
DC 40) and trapped with a magical deterrent:
Energy Drain Trap: CR 10; magic device; touch
trigger; automatic reset; Atk +8 ranged touch; spell
effect (energy drain, 17 th level wizard, 2d4 negative
levels for 24 hours, Fortitude saving throw (DC 23)
negates); Search DC 34; Disable Device DC 34.
