Feature Definitions
Sorcerer Spells: For each personal evolution, you may choose one spell that your drider can cast. This spell becomes a once/day spell-like ability that you know.

If the target is struck, it becomes entangled (no reflex save). The webs have all the same properties as a monstrous spider's web.

Improved Web: Webbing can be used for any number of purposes - rope for climbing, binding enemies, or crafting traps, just to name a few. Evolutionists are encouraged to be creative with their usages, but dungeon masters get final say on whether a certain use is allowable in any given context.
 * If an enemy is bound in webbing, it can make an Escape Artist check against the evolutionist's Use Rope skill check to free itself; or the subject could try a Strength check of DC 18 + Int
 * The webbing, when in use, is only sticky in places where the evolutionist wants it to be (e.g. one end only, for sticking to a ceiling). Webs cannot stick to wet, oily, or extremely hot (fiery) surfaces.
 * Webbing is vulnerable to sharp objects and fire, against which it has an AC of 15 + Int, with 2 HP per inch thickness.
 *  - Evolutionists can shoot webs a distance of 60 feet, as a standard action. This can be used to affix one end of a web to an object some distance away, or it can be used as a ranged touch attack resulting in binding or grappling an enemy, but it does no damage upon impact, unless on a natural 20. In the case of a Critical hit, damage is equal to 1d4 + Str.

Plane Shift: This is a once/day spell-like abiility that functions exactly as it does for the bebiliith.
