Bottomless Sack

#Overview

Bottomless Sack is the evolution of Grab Bag. You get it by opening a chest with a max-level Grab Bag and Sprouting Eyes at any level. Like Grab Bag, it fires other weapons' attacks with its own stats. It makes two picks per shot instead of one, and it copies the evolved form of each weapon. For example, it copies Gravy Flood instead of Gravy Boat, and Hashnado instead of Hash Boomerang. A weapon with no evolution is copied as it is.^[1]

#How it works

• The copy pool is the same 28 base weapons as Grab Bag (see Grab Bag), each swapped for its evolution. Each pick is uniformly random.
• Each volley fires Amount shots, 0.25 s apart, and each shot makes 2 picks. With the Sack's own Amount of 2 plus Tibo's built-in +1 (see Stats), that is 3 shots and 6 random evolved attacks every 1.6 s before cooldown bonuses.
• Every copied attack uses the Sack's damage (20), area (1.2), speed (200), duration (2 s), pierce (2) and knockback. The evolved weapon supplies only the attack shape and its special parameters, such as Gravy Flood's growing, drifting pools.

#Tips

• Every pick counts as one more attack, so amount bonuses scale the Sack quickly: each extra Amount adds another two random attacks per volley.

#Stats

Values are the raw numbers from the game's definitions, before Tibo's global stat multipliers, difficulty and time scaling. In play, Tibo's base stats add +1 amount to every weapon except aura, cone, nuke and ring weapons, and make every duration ×1.25 (see Stats). Field names in code are the game's internal names. Attack descriptions such as “Melee slash” are this wiki's summary of the internal attack kind.

Evolutions have no level-ups in the game data; they use these fixed raw values.

#Behaviour parameters

Raw parameters of the attack (behavior), copied from the game definition. What they do in play is explained under How it works above.

#Obtaining

• Get Grab Bag to level 8 while owning Sprouting Eyes (any level), then open a chest. See Evolutions.
