Ok. Ogres east of castle wars from behind wall with ranger set, fury, zammy book and iron knives. do that 58-62 ish range
62-70then do waterfall quest for safespot for firegiants where you earn alomst as good exp while also pulling in 100k an hour in drops.
or 62-70 at yaks witrh archer ring.need to cpomplet first femmy trials and start the second quest i think. Idk quests are gay.
use iron knives for everything , but with 55 slayer broad bolts are 60 gp each and hit as high as addy consisntanly . Void is only good on low def monsters and or/ 80 range. I have 90 range and train with void and i hit 35's on blue drags with 60 gp bolts. it is truly awsome. Wether you decide to keep training or range or keep it at 70 have a fun time. I camped from 62-77 range and firegiants and the rune scim drops really helped pay for some alchs to 82 mage
now looking back at other posts i see that you inquired about cannoning monsters.So i'll edit my post and discuss them here. Some places i sugggest would be daggnoths, ice trolls, and rock crabs. Rock crabs for 1 def pures which i'm guessing you are. Daggnoths require food because they hit with melle, and range. I used to cannon them when i was 70 def with guthans on and the rannar seeds and such paid for about a 1/4 to a 1/3 of the training. Ice trolls have a good guide on zyzbez i think or you could just google it. But apparently with pray potionsand cannon it is possible to still make profit with the rune kite shield drops.
Remember as far as sythe goes it is great for cheating advice, its community, and buying accounts/gold and such. But Skilling advice really should be googled.
I hoped I helped.
