Grab Bag

#Overview

Grab Bag borrows other weapons. Each shot picks a random weapon from a fixed list and fires that weapon's attack, such as a gravy pool, a boomerang or a pan swing. The damage, area, speed, duration, pierce and knockback all come from Grab Bag's own stats; the picked weapon supplies only the shape of the attack and its look.^[1] You do not need to own the weapon that gets copied.

It is offered as a level-up card. At max level, with Sprouting Eyes owned, a chest evolves it into Bottomless Sack. The Sack pulls two attacks per shot and copies the evolved forms.

#How it works

• The list. The copy pool is every base weapon whose attack is a fired or placed attack: slash, targeted or facing shots, lobs, boomerangs, pools, strikes, bouncers, explosives, mines, chains, novas, homing shots, beams, rain and spirals.^[2] In this build that is 28 weapons. Weapons that work differently are left out: turrets (Fry Cook Sentry), orbiters, auras, cones, familiars, guards (Hash Brown Shield), tethers, rings, nukes, and the newer special weapons. Grab Bag can't copy itself. Each pick is uniformly random.
• Firing. Grab Bag only fires when a pest is within targeting range, which is 0.7 × the larger side of the play field. Each volley fires Amount shots 0.25 s apart, and each shot is one random pick. Tibo's built-in +1 amount (see Stats) gives 2 picks per volley at level 1 and 4 at level 8.
• Because the copy uses Grab Bag's numbers, a copied attack can behave differently from the real weapon. For example, a copied pool's lifetime is based on Grab Bag's 2 s Duration, and a copied pan swing does not get the Frying Pan's elite charge.

#Tips

• Grab Bag's damage per hit is the same whatever it copies, so its value comes from variety: crowd attacks such as pools and novas, and single-target shots, all hit at Grab Bag's damage.
• Amount bonuses add more random picks per volley, so Sprouting Eyes helps it now and is also its evolution catalyst.

#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.

#Level progression

Each level-up adds the listed change to the weapon's raw values. Totals are cumulative.
