The absolute best for herb farming would be:
- Ectophial for Port Ghosty patch (Requires Ghosts Ahoy quest)
- Lunar teleport to Catherby for that patch (Requires 87 Magic, Lunar Diplomacy quest, Lunar spellbook active)
- Explorer's Ring 3 for Falador patch (Requires Lumbridge hard tasks done)
- Ardougne cloak 4 from Ardougne tasks for that patch (Requires Ardougne elite tasks done)
- Lunar teleport to Trollheim (Requires over 40 hours of helping at the Livid farm)
- Juju farming potions to boost herb yield (Requires 74 hunter, 70 farming, 64 herblore)
- Magic secatuers to boost herb yield (Requires Fairytale Part 1)
- Scroll of life to have a chance of getting seed back from patch (Requires 10k dungeoneering tokens to buy)
- Supercompost/Fertile soil lunar spell
- Falador shield 2 to increase farming xp at Falador patch (Requires Falador medium tasks done)
With those things, you'd be able to do a herb run in under 4 minutes and they would be more profitable, but some of the requirements are pretty extreme and are not needed to enjoy profitable herb runs.
- Ectophial is the most important item since that patch is not viable for use being so far away from any other teleports.
- Catherby teleport can be substituted with regular spellbook Camelot teleport, not much further away.
- Explorer's ring can be substituted with Falador teleport, but it is quite a bit farther away
- Ardougne cloak 4 allow unlimited teleports directly to the farming patch, but has really high requirements. The hard version allows one teleport per day and is really recommended to have that at least. Ardouge teleport is quite a walk, and if you have to use that and Falador teleport, you might not be able to reach all 5 patches on one dose of Juju farming potion.
- I would not recommend Livid farm Trollheim teleport to even the most diehard farmers. Over 40 hours of work to save 30 seconds per herb run? You'd have to do over 4800 farming runs for that to be worth it. Just use Trollheim teleport from regular spellbook or Trollheim tablet (Love story quest) and run west. You must start at this patch if using Juju farming potion.
- Anything else would just boost yield/XP and is not necessarily needed for someone new to farming. You'd overwhelm them listing all the stuff that is needed if they don't have the requirements for it.
