Bulwark
Bulwark is a chassis part in Rivet Rivals, the free robot-building auto-battler for iPhone and Android. At level 1 it gives +1100 max HP, +5% protection.
Every robot in Rivet Rivals equips exactly one part in each of five slots: chassis, weapon, armour, gadget and chip. Bulwark fills the chassis slot. It joins the reward and crafting pools once your highest-ever attack rating reaches 20.
