of being a detached brain makes emotion components
difficult. When casting a psychic magic spell with an
emotion component, a brain cylinder must make a
concentration check (DC = 15 + spell level) in order to
cast the spell successfully.
BAB: A brain cylinder has a base attack bonus of
+1 but cannot make attacks on its own. If the base
creature had class levels and thus retained its Hit Dice,
the brain cylinder’s base attack bonus is the same as
that of the base creature.

Abilities: A brain cylinder is treated in many ways
as an object as well as a construct. It has no Strength
or Constitution score, and its Dexterity is reduced to
0 (thus giving it a –5 penalty on all Dexterity-based
checks). The trauma of being transplanted from a
body to a cylinder results in a –2 penalty to the base
creature’s Wisdom.
Feats: A brain cylinder loses all feats gained as a
result of racial Hit Dice save for one feat of its choice.
A brain cylinder retains all feats gained as a result of
class levels and associated Hit Dice. Note that some
feats become useless for a brain cylinder if it no longer
qualifies for them.
Skills: A brain cylinder treats all skills as class
skills. It retains all skill ranks gained from class levels.
The brain cylinder loses all skill ranks gained from its
racial Hit Dice, but gains skill points equal to 2 + its
Int modifier (minimum 1) if it gained 1 racial Hit Die
as a result of applying this template. Although a brain
cylinder loses the base creature’s skill ranks, it retains
the knowledge it had as that creature and gains an
insight bonus to the base creature’s skills equal to the
base creature’s skill ranks in that skill.
