I'm a big fan of Canoptek units for Necrons, and in fact am fluffwise trying to field only constructs and vehicles when possible to represent a Tomb World that hasn't yet fully awoken. One issue that I have is how very few of the
HQs are helpful to such a list. According to some of the lore on Canoptek Spyders, they tend to serve as directing the constructs until a Lord awakens, so I thought we could discuss how to best represent that.
First of all,
If a trio of constructs are acting in concert, one will take command and harness the processing capability of the other two to create a gestalt supermind far greater than the sum of its parts. This hyper-efficiency is passed on to all Canoptek Wraiths and Scarabs in the vicinity, allowing for Spyders to affect a coordinated and precise response to any threat.
So, we'll say something like:
Canoptek Spyder Overseer,
HQ slot. The unit comes with one Canoptek Overseer and two Canoptek Spyders. Spyders are at their normal points, the Overseer takes a 30(ish?) point bump to become a
Character. As I recall, Character on even one model means the entire unit won't be able to be targeted, so I figure it should be pretty pricey.
The Overseer can't take normal warlord traits, but always gains the following:
Constructed Sentinel: Friendly
<Dynasty> Canoptek units within 6" can reroll Hit rolls of 1. In addition, Friendly
<Dynasty> Canoptek units within 6" can perform Heroic Interventions, as though they were Characters.
I feel like rolling the aura ability into the warlord trait helps reinforce the fact that even a low-ranking noble or cryptek takes precedence over the construct, but should there be a hard limit to where one can't be selected if you have an actual Necron Character present in the army?
