Tl:dr: It’s fine.

It was due for a nerf. It’s too good. Every time I’d get one, I’d say in my head, “Oh, guess I’m playing easy mode.” I will wear a Ring of Haste over any other ring or artifact. That’s a bad sign gameplay wise. It does too much.

• Let’s you trivially escape melee without using any tricks or consumables.
• Let’s you easily chase down Scorpios.
• Makes it super easy to dodge evil eyes.
• Makes you use less food.

At any rate, I’m playing the beta. This nerf didn’t change any of that. I had a +1 Ring of Haste for most of the game. I could kind of tell it wasn’t as good as it used to be, but it didn’t matter. It’s still the most OP ring in the game at low levels. I’d say Ring of Wealth is more powerful, but that one only really shines when you dump upgrades into it.

The only thing that’s noticeably different is that a +3 Ring of Haste will no longer double your movement speed. A +3 one used to give you +107% movement, but now it only gives you +91%. Not all that big of a change. Approximately one turn in nine you won’t get the free movement you were expecting like the old ring would have.

With the old ring at +0 you get a free movement once every 5 turns. Now it’s once every 5.7 turns. Hardly noticeable. I never counted turns when using the old ring. I knew eventually I would gain distance from melee by running, or catch up to a Scorpio when chasing one.

If you make the new ring +4, you get +124% movement. So one extra upgrade to exceed double speed.
