I have actually been doing a terraria playthrough for about a month now, and this playthrough I've actually been fishing often, and it's started to make me like the angler; as I've only done 12 quests for him and I already have all of the ingedients for the Fish Finder, and a Super Absorbent Sponge. He must've learnt to give me good items from the 88 times I have killed his ancestors in previous playthroughs, eh?
