My typical enchants:
Weapon: Crusader, I love how much damage it does to shadow creatures, ghosts, mummies, etc in hard mode, and especially love not having to use bombs to finish mummies off. It’s amazing how much cloth and solar essence you get between that enchant and wearing a burglars ring.
Pickaxe: Swift, because every other pickaxe enchantment doesn’t do much for me on an iridium pick.
Axe: Shaving, a little extra wood is always a good thing with how much of it I go through.
Hoe: If I haven’t completed the museum collection, Archeologist for any artifact spot stuff I need. If the museum collection is done, then I go with Reaching to plow land quicker, which is good for winter day 1 when you’re planting winter seeds.
Watering Can: Reaching by default, which is also good for planting winter seeds on Winter day 1.
Fishing Pole: Preserving, because longer lasting tackle and wild bait matters more to me than the other Fishing Pole enchants. I used to do Master, but my fishing time declines significantly starting in year 2, so it was basically a waste once I got a certain item that requires a Fishing skill of 15 to get.
