Avenger has pretty low core stats but a huge HP amount.
It is ideal for an energy-free build (for you’d only need to boost it’s heat,cooling and hp,thus maybe forgetting about adding any energy whatsoever)
That would mean either a dual Annihilation build (that is semi energy-free) or a heater (with Desolation,Sorrows,Magma Blasts,Clash) but also a hybrid (called the ‘‘Moving Fortress’’,2 Desolations,2 Annihilations,optional Magma Blast and Clash for a fully energy-free build with high hp and damage)
As for Windigo…That one torso is pretty universal.You can make whatever out of it.
If you wanna use it for a heater,get it hp,energy and one/two more heat engines or whatever,for an electrician get it a lot of energy for it has good base heat and for a phys…get it a little bit of all and more health.
Point is,using Avenger doesn’t give as many options as using Windigo.
I’d say yes.Keep the Windigo and use the Avenger as transform material.
