A simple 1-cost Skill that heals Osti with Summon 5 (upgraded 7). Summon is the resource mechanic at the core of Necrobinder's gameplay — keeping Osti topped off.

Plain, but "keep Osti alive" is a vital role in many builds. Strong synergy with Osti-HP-dependent cards like Unleash and Protector — Bodyguard is what keeps those cards at max damage. The downside is that Bodyguard alone has no offense or defense for the player, so it only earns its slot in Osti-axis decks.

Rating: B-tier (must-have support card in Osti-focused decks)

• Play before Unleash or Protector to top off Osti's HP
• Use as a Summon source after Bone Shard (sacrifices Osti)
• Upgraded Summon 7 makes keeping Osti at high HP much easier
• Only worth including when multiple Osti-dependent cards are present

• Unleash: damage scales on Osti HP, so top up with Bodyguard first
• Protector: scales on Osti max HP — the perfect target for Bodyguard's Summon
• Bone Enhancement: boosts all Osti attacks. Works great with the Osti-keep-alive angle of Bodyguard
• Necromastery: converts Osti HP drops into AoE damage. Use Bodyguard to manage intentional HP swings

• Necrobinder Necromastery Combo Build (A-tier)
• Necrobinder Osti Multi-Attack Build (S-tier)
