Rather than creating a single potent companion, a constructor believes in strength in numbers.
Mass Production[]
A constructor can have more than one construct companion, but he must divide his effective vanguard level between his companions to determine the abilities of each one. For example, a 4th-level constructor can have one 4th-level construct companion, two 2nd-level companions, one 3rd-level companion and one 1st-level companion, or four 1st-level companions.
When a constructor gains a level, he must decide how to allocate the increase among his construct companions, including whether or not to add a new 1st-level companion. Once a vanguard level is allocated to a particular companion, it cannot be redistributed while that companion is bonded with the constructor. He must decommission the companion or wait until the companion dies to allocate its levels to another companion, which he can then do the next time he refreshes his spell slots for the day. The share spells construct companion ability applies to only one construct companion at a time—the constructor cannot use it to cast a spell that affects only a single target and have the spell affect all of her construct companions.
This ability replaces construct companion.
Mass Augments[]
Whenever a constructor gains an augmentation, he must choose which of his construct companions receives it. Only that one construct must meet the requirements for the augment, not any of the others. His other companions do not gain the augmentation. This alters augmentation.
Mass Resonance (Su)[]
When using a resonance, the constructor must activate it upon the companion that has the desired augmentation, and it originates from that construct companion, as normal. Resonance effects that specifically target the companion (such as tactical reposition or energy discharge) only use that singular companion, not any others. This alters resonance.
Vanguard Tactics (Ex)[]
At 3rd level, the vanguard gains a teamwork feat as a bonus feat. He must meet the prerequisites of this feat as normal.
The constructor can grant the benefits of a single teamwork feat he has to all of his construct companions simultaneously, even if they do not meet the prerequisites. Doing so is a swift action, and the effect lasts for a number of rounds equal to 1/2 the constructor’s level + his Charisma modifier. He may only grant one teamwork feat this way at a time. The constructor can do this once per day, plus an additional time per day for every three levels gained thereafter. This replaces shared tactics and the bonus feats gained at 3rd, 9th, and 15th level.
Craft Construct (Ex)[]
At 6th level, the constructor gains Craft ConstructB1 as a bonus feat, even if he doesn’t meet the prerequisites. This replaces the bonus feat gained at 6th level.
Mass Repurpose (Ex)[]
In addition to its normal uses, a constructor can use repurpose to decommission a construct companion, redistributing its effective vanguard level(s) and any augmentation(s) it has to his other companions. If none of his remaining companions qualify for one of the augmentations that was on the decommissioned companion, that augmentation is lost until the constructor uses repurpose to replace the augmentation with a different one that one of his companions can use. This alters repurpose.
Perfect Resonance (Su)[]
Instead of granting the effects of battlemind linkUC, a constructor’s perfect resonance ability grants haste to all of his companions for the same duration. This alters perfect resonance.
