Kitthix

Kitthix is a black spider that can be summoned once per rest with the Black Spider Figurine during the Baldur's Gate II: Shadows of Amn campaign and, if the figurine is imported, also later during Throne of Bhaal.

Appearing as a semi-intelligent huge spider, Kitthix has more in common with phase spiders, regarding abilities and creature stats. It will obey its master's commands for one hour or until slain.

Gameplay

 * Kitthix will use a Dimension Door-like ability to teleport to an enemy, just as phase spiders do, if no opponent is closer than 8 ft.; this can't be interrupted and be done at will anytime.
 * In close combat, Kitthix may switch between opponents, again using her 'phasing' ability for this.
 * Kitthix' three and a half melee attacks per round count as made with a weapon at a range of 1 ft. with a speed factor of 3. In addition to its 1d8 piercing damage, it will cause 3 points of poison damage per second for a duration of 14 s; a save vs. poison with a bonus of 1 is allowed to avoid this.
 * In the original Shadows of Amn without its expansion Throne of Bhaal, the poison might ignore not only magic, but also poison resistance.
 * This is changed with the installation of Baldur's Gate II: Throne of Bhaal and in the Baldur's Gate II: Enhanced Edition, where the poison is natural, so that only magic resistance is ignored.
 * Kitthix is able to use a Web-like ability, Web Tangle, two times per summoning that will catch one enemy in a web and paralyze them – for 3 rounds and a half in the original games, but for only 2 rounds in the Enhanced Edition – unless a save vs. spell is made with a penalty of 2. This ability counts as level 3 spell, ignores spell schools, has a range of 40 ft. and is made with a speed factor of 2. The web can be dispelled and avoided via magic resistance. Kitthix will not use this autonomously.
 * Kitthix' immunity against paralysis in general is removed in the Enhanced Edition.
