I remember in my first ever dnd game after I slayed 32 goblins and the goblin king, I was rummaging around in a chest. My DM panicked and gave me a ring of invisibility and lived to regret it because I was playing a rogue and sneak attacked with the ring of invisibility and one shot an ogre at level 2.

Question: If you tried to Dispel Magic on this, could you "end the effect" by dispelling the effect of the invisibility or would you need to target the ring to disable the ring from being able to make you invisible?

edit: how our DM handled it, the effect can be dispelled if you can target it (we had some see invis up and he made our druid make a hit with disadvantage, which she succeeded at!), and it will drop the effect, but unless the ring itself is targeted, it can just be enabled again. So, that was our table rule.

Late reply, but by RAW Dispel Magic only works on a spell effect; thus you could not end the invisible condition if it is the product of anything but a spell. However, there are the handy spell See Invisibility and Faerie Fire to counter the invisible condition, both of which are lower level than Dispel Magic. Remember, kids, work smarter, not harder.

Can you use a hasted action to become invisible with this? 

It's debatable as the action to go invisible could be seen as being its own unique action, but it's also an action from an item which could be considered to be an object you're using, so the [Tooltip Not Found] action granted by haste would be suitable.

I think it falls to DM discretion and what the player(s) are trying to do with it; the invisibility from the ring is persistent and can't be interrupted so it doesn't seem like there'd be an obvious way to exploit it (unlike being able to re-cast invisibility after it gets interrupted by attacking), so I'd probably allow it personally.

I'm just here for the LOTR comments

So basically, this legendary magic item that requires attunement is the equivalent of a 2nd level spell invisibility but without the concentration and infinite duration (aside from attacking or casting a spell).

yes yes precious

 Yes. It is quite powerful to give any class access to a spell with unlimited uses and duration. Tons of stealth types try to snag things like a Cloak of Elvenkind, attunement and advantage on sight based stealth checks. Compare it to this...?

Also, see Winged Boots. Uncommon, but limited in speed and duration, doesn't just give you the fly spell. 

aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa oh im invisible. WHAT DO MEAN I CANT TURN BACK UNLESS I PUNCH SOMEONE IM JUST TO NICE TO DO THAT NOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO

Ah yes. The lord of the rings ring.

 My precious.

 This shows why dnd copied the hobbit but its okay

More like the Ring of Gyges, which was probably Tolkein's source to begin with.  For the One Ring you would need to add some escalating set of powers of command: it is pretty clear that more powerful people than Hobbits would be able to use it to command the wearers of the other rings, just for a start, and likely exercise dominion over entire armies and kingdoms.  Both rings are meant to represent the temptations of power.

It doesn't say what the attunement is though

Unless otherwise stated, attunement is a generic 1-hour activity that can be completed during a short or long rest. Very few items actually specify their attunement process.

Imagine the rogues sneak attack combode with this!

the way its the ring of power is crayzy

The Ring of Power, only silver.

This with elven boots is too over powered. Silent and can't be seen. I will cast wish to try and get it
