I've never made a range tank, but I'm pretty familiar with quests and whatnot. On behalf of the training portion, I'd just say the regular:
1-20 range cows.
20-40 range minotaurs
40-75 or 99 at fire giants
75-99 green or blue dragons, (for profit)
or....
75-99 chinning at Ape Atoll (need to have started MM) - expensive method
While training range, use long-range.
I'm not expert in range, I'm just assuming.
Quest wise, you'll want to do a few imporant quests. Truthfully, barrow gloves are the best range gloves in the game, at least in 07.
Basic Quest Outline:
- All tree gnome quests, and complete MM (if you're looking to get barrow gloves).
- RFD (for barrow gloves)
- Animal Magnitiesm + the sub-quests (for ava accumalator).
- Lunar Diplomacy (for lunar magics)
- Desert Treasure (for ancient magiks and for barrow gloves)
- Roving Elves (only if you want a Crystal bow, or shield)
- Dragon slayer (ability to wear dragonhide top + good defence XP)
- Holy grail (optional but 2 QP + 11K prayer and 15K defence XP)
...that's all I can think of the top of my head, but like the person above said youtube should have loads of guides or even searching google. Hope this helped a bit.
