Question about champion warcry spectre build

I recently come across some champion builds on ninja, They all wear ambu charge chest, got lots of warcrys and their spectre supports are increased aoe, more duration , efficacy, .....
Any idea what spectre they might be using?

Did you find out what spectre to use?

new aurabot maybe.

there is a defensive spectre casting anti-projectile field that need more duration support to increase its up time

Yes it was some kinda cheap aurabot using defensive and aura_spectres instead of auras, Not a solo build unfortunately
