I'm trying to find a clickable heal item to go along with my manastone. Other than the ES legs, is there anything out there for druids?

no

There's the Squad ring from Rivervale, but it's not useful for manastone purposes, one charge of light healing (~30hp), can be recharged through a turn-in in Rivervale though, but that's a major pain to trade back and forth.

POG Mask. Drops from POG Prince. Right Click Tree regen lol. Fungi Tunic or Staff, too. I think that's about it for Druids :(

ES Legs. Cast diamond skin on yourself repeatedly.

I think people give way too much credit to ES Leg/Manastone combination.

ES Legs is SLD... basically a 200 hp heal...

Casting time on the legs is 12 seconds..

So lets say you heal 4 times per minute, and then use the manastone for 12 seconds per minute.

Giving you 800 healing per minute for free.

Manastone is a 3:1 ratio.

800 / 3 = ~267 mana from manstone.

Meditating for the same minute = 23*10 = ~230 mana.

=-=-=-=-

These pants can get you an extra 37 mana / minute compared to meditating. Which is equal to 3.7 extra mana per tick.

Not as stellar as people seem to think.

I kinda cheat for my clickable heal - I dual box a cleric :) I stone down, she ch's, rinse repeat. Once I'm fm, I stone down on her. Think it takes about 3-4min for both of us to go from oom to fm.

But yeah, as for items, we are stuck with ES legs. Druids cannot be clerics in terms of using a stone to go from oom to fm. It just doesn't work.

The best option as a druid with a stone, is to keep your regen very high, such that you can do a stone proc every tick. Provided you can keep your regen at a decent rate (mine is just under 60 per tick), that means you get 20mana per tick from the stone while maintaining life. Over 3 minutes, you get 600mana, and it costs you 300mana of casting NR to keep this up during the 3minute time span. So basically, if you are in solb or the like, you can use this to gain about an extra 100mana per minute.

Granted, it's hard to keep this level of efficiency. If you are getting hit a lot, then you can't stone as much, and everytime you stand up you could potentially miss a "med" check by the server to make sure you are sitting. But overall, I notice a significant difference in doing this in my old world adventures.

You can buy a horse and while you're sitting on it you are "standing" and able to cast spells, but you still get medidation mana regeneration. In this way, you can get the benefits of both meditation and es-legs/manastone.
