I do mith gloves from tut island from scratch for 15m
Takes about 4~ hours to do. I even broke the previous record which was 4H 1M.
Addy gloves is one more subquest and the fastest is Lumby guide which requires nature spirit and a couple of other quests so youd be 13 def minimum.
Addy gloves from scratch around 20-25m
Rune gloves requires a bunch more quests because youre only other 2 options are King Awowogei or Sir Amik Varze. Awowogei has high stat requirements and Sir Amik Varze has high qp requirements (107 qp)
From scratch for rune gloves is gonna be like 70m+ easily.
Also, you say some atk/str not that high. Mith gloves from scratch requires Waterfall so 30atk/30str minimum. And this is to make the Shadow of the storm boss not take 6 hours to kill. Then pick range reward which is 10k xp from 1-27 then train to 30 for big chompy bird hunting. Usual ending combat stats for mith gloves is 30 atk, 30 str, 25 hp, 20 magic, 30 range, 1 prayer
