Cookies are categorized by their Type (e.g., Charge, Defense, Ambush, Magic, Ranged, Support, Healing, Bomber) and their Position (Front, Middle, Rear). Understanding these roles is the first step to building effective teams.

- Charge/Defense (Front): Tanks, absorb damage, protect allies. Examples: Hollyberry Cookie, Financier Cookie.
- Ambush/Ranged/Magic (Middle/Rear): Damage dealers, focus on eliminating enemies. Examples: Espresso Cookie, Sherbet Cookie, Black Pearl Cookie.
- Support/Healing (Middle/Rear): Provide buffs, debuffs, and healing. Examples: Cotton Cookie, Pure Vanilla Cookie, Cream Puff Cookie.
- Bomber (Middle/Rear): Area-of-effect damage dealers, often with crowd control. Examples: Sea Fairy Cookie, Cherry Bomb Cookie.
A balanced team typically includes at least one strong tank, one dedicated healer/support, and 2-3 damage dealers. The specific mix will depend on the content you're facing.
