Something like this? I do wonder if the Tumble check should be opposed instead of a flat DC. I'm also not sure whether to make it ranged or melee. It probably needs some wording about range from a specific body.
Sticking Touch (Ex???): As an attack action, a Veiled Maidens may make a ranged touch attack (range 10 ft??, no range increments) that, if successful, connects one of its veils to its opponent. This connection grants the Veiled Maidens a +2 insight bonus to AC and attack rolls against that opponent as long as the veil remains attached. The connection can be broken only if the opponent succeeds on a DC X Tumble check, the Veiled Maidens ends its turn with the opponent outside the range of Sticking Touch, or the Veiled Maidens chooses to release the connection.
Proposed revision to Multiple Actions:
Multiple Actions (Ex): Whenever the Veiled Maidens performs an action, it can perform that action up to seven times - once for each of its bodies. Thus, if it makes a standard attack action it will make up to seven attacks at no penalty, even if it moves or charges during the round. The number of multiple actions it can make is reduced by one whenever one of its bodies is destroyed (see Multiple Bodies). When the Veiled Maidens performs an action, all of its bodies perform the same action (either against the same or different targets), with three exceptions.
First, a Veiled Maidens' body can use the Aid Another action to aid one of its other bodies perform an action. Thus, if three bodies use Aid Another, they add three sets of +2 bonuses to the attacks (or other actions) of the Maidens' remaining four bodies, distributed between them however the Veiled Maidens desires.
Second, if the Veiled Maidens performs an attack action, not all attacks need to be of the same type. For example, six bodies may make melee attacks, while the seventh makes a Sticking Touch special attack (see below).
Finally, if a body qualifies for an Opportunity Attack, that body gets a single opportunity attack - the other bodies do not get opportunity attacks too. The Veiled Maidens only gets multiple opportunity attacks if multiple bodies qualify separately. The Veiled Maidens can make up to seven opportunity attacks per round - once for each body - plus any bonus opportunity attacks it gains from Combat Reflexes or similar abilities.
