The Cool Whip is a Hardmodewhip that, upon striking an enemy, creates a temporary snowflake projectile that chases nearby enemies, dealing 10 damage to them on contact. The summoned snowflake ignores 30 enemy defense and is not affected by damage bonuses outside of banners. If a snowflake is already summoned, attacking with the whip will reset its timer instead of creating a new one.
Like the Firecracker and Dark Harvest, the Cool Whip forgoes summon tag damage for an on-hit special effect. This results in it being more effective as a direct weapon, but prevents it from enhancing minion damage.
Tagging an enemy with a different whip will not cause the snowflake to disappear. This allows it to be used as a support weapon for crowd control.
Although the snowflake does not disappear, it will remain stationary at the position of the last killed enemy. It will not move until another enemy gets into its range.
It is the only whip in the game with a tag that does not interact with minions in any way.
