Ring of Pain

The Gear

- Double Candle
- Hermit's Tiara
- Weightless
- Polearm

The Stats

-Speed
As with every Tiara run this should be your main priority. Get 21 as soon as possible and aim to keep it there.
-Health
The only damage you should be taking is emergency stealth attempts, bile bags and hidden spine backs after getting Polearm. You may also need to tank a ranged hit from Owl. Rush bile bags and the rest can be avoided with careful planning and movement. 25 - 30 is fine.
-Attack
In theory you could do this with 0 or less attack if you have the patience to beat Owl 1 health at a time. Get it high enough to deal with potential blockers in the final fight and anything more is a luxury/time-saver. I finished with 14 and managed fine.
-Clarity
Not a big deal. Just keep it above 0 for emergency potion use and extra soul gain.
-Defense
High speed + Polearm makes defense entirely pointless. The baby loombirds in the final room and Wretched Amalgams you don't kill early are the only things that will be fast enough to hit you at 21 speed. You'll have the Polearm in the final and should rush Amalgams whenever you see them. The rest of the damage you'll receive bypasses defense anyway. Like Clarity, try and have it above 0 for the final fight but don't stress too much.

The Run

-Dungeon 1
Pick Double Candle and start with Hermit's Tiara. Clear the room and empty the chests, rerolling until you get Weightless. If you don't, restart. Weightless gives you +7 Speed from the start, allowing you to get to 21 faster and giving you room to upgrade other stats.
-Dungeon 2 - 13
Kill everything. Prioritise Scroungers and get every stat card, including cursed ones. Take as many side rooms (except Chills) as possible to maximise Souls gained. Make sure to go into Reprieve and kill Owl to weaken him for the final fight.
-Dungeon 14 - 16
Gold chests should be spawning now. Crack open the first one and reroll until you get the Polearm. If you spend all of your souls in Room 14 there is a possibility you get enough to have one more go in Room 16. This is pure RNG, it took me 4 runs to get a Polearm.

The Boss

First off you should freeze the enemies closest to you and kill any scroungers. The plan is to stack the ring with ice cubes and neutral cards you can use to put between you and Owl. The ideal position to be in when he does reach you is;
Owl > frozen enemy or neutral card at front left > neutral card at front right (or the reverse if he comes at you from the right)

Now all you have to do is hop over the front left card and damage Owl with the Polearm and then hop back to the right away from him. Repeat this until he goes back into the middle. Avoid his ranged attacks and freeze more enemies on your way to destroying a candle to force him back into the ring.
Now you can either play safe and wait for him to come to you, freezing more enemies while he's stunned or go to him to get in some free shots. Either way you should revert to the tactic of hopping over a card to hit him with the Polearm and hopping away until he goes back to the middle.

He will occasionally spawn more enemies. These loombirds can make things complicated and you should aim to Polearm Freeze them in the baby phase so they don't transform to track you down, which may end up with you pinned between Owl and a Loombird, forcing you to tank a hit as you escape past the weaker Loombird.

All that's left is to repeat this dance until he's dead which will take at most 1000 turns if you decided to not upgrade your damage and not kill him in the Reprieve Dungeon.
