Angler

The Angler is an NPC concerned exclusively with Fishing, who appears as a young boy. He doesn't sell anything, but rather assigns quests to players. Quest objectives generally involve catching him rare fish from particular biomes, for which he dispenses various rewards.

On the, he will throw Frost Daggerfish at nearby enemies when threatened.

The Angler is first encountered as Sleeping Angler randomly sleeping on the sand or on the water surface of an Ocean biome. He will move in when:
 * There is an empty House.
 * The player has interacted with him and has woken him up.

Initiating a quest

 * The day's quest is determined at 4:30 a.m. each day, regardless of whether or not the Angler has been spoken to.
 * Speak to the Angler and click his "quest" button.
 * The Angler will give the player a tip on where to find the fish.
 * The player will require a Fishing Pole, Bait, and a sizeable amount of liquid (see Fishing) to catch the quest fish.
 * The item will only be catchable while its quest is in effect (from 4:30 a.m. of that day until 4:30 a.m. of the next day)
 * The quest fish can only be caught if it is not already in the player's inventory.
 * Speak again to the Angler to complete the quest.
 * The quest fish must be in the player's inventory
 * The quest fish in the player's inventory will be replaced with a reward.

Quest rewards
After a quest has been completed, the Angler will reward the player with one item, a number of Coins, and possibly some bait. Note: After the 150th completed quest, the chances permanently reset to their base rates below, as if the player was always on their first quest each time thereafter (this is possibly unintended). Coins are not affected by this and continue to scale up to a maximum of per quest.
 * Item chances: The chances of functional, non-potion items gradually increase from their base rates (shown below) with the number of quests completed: they become more likely (and others less likely) as more quests are completed.
 * At 50 quests, the chance of a receiving a functional item reward is approximately twice the base rate.
 * At 100 quests, the chance is approximately four times the base rate.
 * At 150 quests, the chances are the highest, at about six times the base rate.
 * Coin quantity: The number of coins awarded increases with the number of quests completed, and is rounded down to the nearest gold coin (or silver coin, if less than ), up to a maximum of . The average coin reward is approximately, plus per completed quest, before rounding. These values are doubled in Expert mode.
 * Bait chances: The Angler may additionally reward the player with an amount of bait, with chances scaling from ~50% on the first completed quest to 100% by the 50th quest. The average quality and amount of bait given similarly increases with the number of completed quests, up to a maximum of 7 Master Baits.

Trivia
