With a WW/nightmare, dragon/nightmare, or rune beetle/nightmare combo, you can easily hunt the regular dragons, drakes and wyverns in Destard. You have to be somewhat adept at knowing how to get them to follow you if there are greater dragons around and you have to be on your toes for new greaters spawning on top of you if anyone else is in the dungeon hunting them. But it's a good place to hunt, especially if you're trying to acquire leather to donate at the library while training your pets and gaining in honor.
The hedge maze is a good spot for pet training.
The sphynx is another popular spot. Safe, boring, okay gold, usually heavily camped depending on the shard.
Blood eles in Shame or Ilshenar are always fun. Poison eles in Shame are also good.
Rune beetles in Tokuno are good gold. So are the tsuki wolves if you don't feel like dealing with spellcasters. Lesser hiryus in the lower part of Isamu-Jima would also be very doable. You'll encounter an oni or regular hiryu occasionally and of course ninjas aplenty. Your pets will need serious vetting and maybe some help from your mage if you decide to kill regular hiryu. GDs stomp on them pretty well, but I usually have a little trouble with them using other pets, especially if a ninja decides to show up.
If you have an archer that needs arrows, you can also work the champ spawn in Twisted Weald up to the level with centaurs and kill them (no karma loss) for gold and arrows. Or go to the serpentine passage and kill the centaurs. (Centaurs also give a little bit of spined leather.) Can also kill the serpentine dragons there until your karma starts to run out, unless you enjoy dodging pixies.

You can kill one of the types of meers for bolts. Drawing a blank on which one you kill. You'll have pretty significant karma loss, so it may not be worth it to you. There's also the whole elemental canyon area you can explore and hit up the poison and acid eles and nightmares. The Justice Gate area is also fun. Or go kill cyclops and titans near Honesty gate. There's also Exodus dungeon past the gargoyle city. Or Blackthorn's castle in Ilsh (better to go there as a group.) Could also buddy up with some friends and visit the two ancient wyrm spawn areas in Ilshenar.
Sorry this is kinda run-on. Tired and it's late. But a few ideas to get you thinking. Have fun.
