The Eel Slapper is a Whip obtained via Fishing in the Ocean. Its range is slightly better than the Leather Whip in terms of range, reaching up to 7 tiles away and dealing critical hits 6 to 7 tiles away. Like all Whips, the Eel Slapper only deals critical hits at the tip, cannot go through walls or deal random critical hits, and pierces all enemies it hits.
Its best Modifier is Godly. Although Ruthless provides better base damage, both Godly and Ruthless versions of the Eel Slapper deal around the same amount of damage when dealing a normal hit and a critical hit.
This weapon is a reference to Monty Python, and is a joke weapon.
Despite the terrible reach of the Eel Slapper, it is the second-most damaging whip in terms of base damage during Pre-Hardmode, the first being the Molten Chains.
