Gensokyo/Haniwa Commander Insignia

The Haniwa Lance Corporal Insignia is a Hardmode accessory.

For each filled minion slot, it increases the wearer's defense by 2 and increases all damage except summon damage by 3%. The number of filled minion slots is rounded up when calculating the bonus, e.g. a single spider minion (0.75 minion slots) grants the same buff as a full minion slot.
