The High Concept: Additional abilities that can be added to the classic handy haversack magic item (with the cost, weight, abilities and requirements added to the normal information for a handy haversack).
The additional abilities included are:
- Handy Holster: Your handy haversack includes a weapon belt.
- Hasty Haversack: You may remove an item from the handy haversack as a swift action.
- Haversack of Holding: Your handy haversack's main compartment holds as much as a bag of holding.
- Horrific Haversack: A horrific haversack is larger and heavier than a typical haversack, because it’s main compartment is actually a small wooden chest.
- Homogenous Haversacks: Homogenous haversacks are a set of handy haversack that share a common set of extradimensional spaces.
