So another thread made me decide to go ahead and try my hand at magic item creation:
Headpieces of communication:
These items can be made separately but must be attuned to a Helm of the Leader to have any effects. Any number can be attuned at one time but there can only be one Helm of the Leader active.
Attuning is done by submerging a helm in a basin of salt water with a Helm of the Leader and electrifying the water.
All gear grants the following abilities:
Cannot be surprised unless every creature in attuned gear is also surprised.
Gain a +1 competence bonus on any Aid Another action as long as aiding a creature in an attuned helmet.
Helm of the leader
At will:
Telepathy communicate with any creature wearing an activated piece of the headgear.
Mass messages: the leader can send out messages of three words or less to all creatures wearing an attuned item.
Locate creature: the wearer is always aware of the general location of any creature wearing an attuned helm within one mile.
Observe: Call up a silent image showing what any other member sees. This image is good enough to allow perception checks and make the leader subject to visual attacks, perception checks are at a at a -2 for quality degradation and saving throws against visual effects are at a +2 bonus.
Big Picture: As a full round action the wearer may create a silent image showing the locations of each creature in attuned gear and their surroundings as seen by the creature. These images are merged for greater clarity and awareness.
Teamwork: May choose one teamwork feat to grant all creatures in attuned gear. This must be a feat possessed by one of the creatures but not the wearer of the Helm of Leadership. The feat can be changed as a full round action.
Leadership: Any command check is made at a +2 bonus for other creatures in attuned gear.
Mask of the infiltrator
A black knit cloth hood with reddish lenses in it. The wearer of this hood can at will place an arcane mark like mark on an object or person, this mark is only visible to others wearing attuned gear and not on the person, it is undetectable outside the gear. The wearer can change the appearance of each mark as wished.
The following function as long as they are within sight of others in attuned gear:
The wearer gains the benefits of a Tactical Acumen spell.
The wearer may treat their level as 4 higher for purposes of Uncanny Dodge's immunity to flanking.
Helm of Support
This helm provides a constant status spell on all other creatures wearing attuned gear.
Locate: at will the wearer can use locate object on another wearing attuned gear.
Percisce rays: any spell targeting a creature in attuned gear that requires an attack roll instead automaticly hits.
Aid: any ability that grants bonuses within a certain range has its' range changed to "on sight" for all others in attuned gear.
Lenses of the Arcanist
Observe: Call up a silent image showing what any other member sees. This image is good enough to allow perception checks and make the leader subject to visual attacks, perception checks are at a at a -2 for quality degradation and saving throws against visual effects are at a +2 bonus. They may also use this to make Spellcraft checks to identify spells and effects at a -2 penalty through others eyes.
Aid vision: Divination spells may be cast through the eyes of other members. Treat this as the Share Spells power with any creature in attuned gear. Both the caster and target gain the benefit of the spell however the wearer must be observing the new target, if they look through the eyes of another, the spell ends.
Targeting: As long as they maintain line of effect, the wearer may use the vision of another through the observe power to target spells.
Helm of the follower
The wearer of this helm gains the effects of a Tactical Acumen spell.
Flanking the wearer of this helm only gives a +1 bonus.
Both of these powers only function within sight of another creature in attuned gear.
So those are some of the ideas, how do they work for a group of linked magic items?
Some of the abilities may be too powerful or need tweaking.
ALso what kind of cost/CL/spells should be needed to make them?
Other comments?
