Here is my opinion on your list, obviously in the end it should be about what you find fun so take it with a pinch of salt.

 

 

Black demon - Blocked, too long. I would do these, they are great experience and crimson charms.

Dark beast - Not 90 yet, but heard they are usually skipped. I don't normally skip these, they are good experience.

Gargoyle - Skip, cbf with hammer. Granite mauls are worth something nowadays, and hammers aren't that annoying.

Greater demon - Do em, good crimsons + clues. Not great charms, one to consider blocking.

Skeletal Wyvern - Skip, too hard, too long. Worth doing for the crimsons.

Spiritual Mage - Nearly 83, should these be blocked? I wouldn't block them personally, they don't dorp charms but dragon boot drops are fairly frequent (1:120) and worth a bit of cash.

Warped terrorbird - Blocked. Consider unblocking these, profitable and great experience.

Waterfiend - Blocked. Best crimson charms you can get via Slayer, I highly recommend you unblock.

Definitely agree with the above poster on Waterfiends and Gargoyles.

In regards to spirit mages and dark beasts:

 

Never block spirit mages, ever. Good exp, good cash, multi combat(combat familiars work) and a fun task. What more could you want?

 

Dark beasts are mis-understood. Spend some money on prayer pots and you thats a LOT of afk'able slayer exp. With good equips, high attack and a black/slayer helmet their defence isn't even all THAT high for a whip+defender to hit through. The only reason I would consider a GS here is because of the enourmous prayer bonus. On a task, a whip has enough accuracy (you could even pray 5% or 10% accuracy along with pro melee) Who doesn't enjoy the rare dark bow drop, either? When you get 90 slayer, it may take a long time before you find your perfect inventory (if you need any food, pray pot:sup set ratio, etc.), I think people are put off by this.

 

I agree with everything SirHartlar said, except wyverns (I hate them aswell, despite charms/drops) and warped birds (pain in the rear for lazy people like me :razz: )

 

Out of your list I would advise blocking/skipping hellhounds, the charms suck and they're crowded. Personally, I believe you should do black dragons properly or not at all. Kill adults/KBD's or skip them. Babies provide bad exp and bad drops but I suppose if you're interested in slayer points you should continue killing babies. Lastly, do those mith dragon tasks! They're practicly giving you slayer points and piety+slayer helmet takes them down so fast that you'll never get bored watching your kill speed compared to those campers using rune-xbow.

 

 

Of course, everyone slays a little differently. Do it the way you enjoy it.
