The goal of this build is to make effective use of the Bloodletter Class Mod. The Version 0.m amp shield will provide a significant damage boost while your shields are full but will partially drain it. Bloodletter synergizes with Vampyr and Rushin Offensive to restore your shields and maximise the amount of amp shots you get.
Capacitive Armature and Sabot Rounds.
Since splash damage with Vampyr is the only way to heal Iron Bear. Setting one arm as Capacitive Armature and one as Corrosive Sabot is a great general purpose set up. Double Capacitive armature can also be used as a faster mob clearing set up with no sustain.
Playstyle: The version 0.m is an amp shield that will provide a significant damage boost for the first shot of a weapon provided you are at full shield. The Bloodletter Class Mod, combined with Vampyr and Rushin Offensive, restores any shields lost, more or less guaranteeing an amp bonus on nearly every shot.
Version 0.m is the recommended shield for this build.
The Rerouter and One Shotter are both good amp shields but lack the damage bonus provided by the 0.m. If you don’t have a 0.m then these are good substitutes. Since Iron Bear use in this build will be minimal anoints are not important but Elemental ASE will give a minor damage increase
