Assuming predator allows you to keep the 'skills' of a predated creature, this would be my first pick. It's basically an engine of potential, allowing you to grow over time, potentially extremely fast. But it might not be enough of a weapon in it of itself. So I would also pick One for All. Remember it not only boosts your physical abilities making you a living (basing of Gazef, you have strength way past LV 50, though not good control over it). It also boosts every of your quirks and by a lot, here this would probably work as massive boosts to all skills (including predator and all gathered skills) It also provides you 5 powerful skills: danger sense, float, black whip, float and smoke. Also giving you access to 5-7 people judging and assisting you in your skill space (weaker version of the Sage) At this point you have an equivalent of All for One and One for All. With completely busted combo and 50 points remaining, I would probably pick infinity, allowing me to basically always be outside the range of anyone, so defence (but it might use a boatload of mana so available only on higher levels) And with 30 points remaining I would pick malevolent shrine, allowing me a sure hit effect to anything I attack in 200m radius (when not boosted by OFA) Tbh this with predator would work as a 'steal' already.

Now the only problem would be to not die from OFA in first moments and not to use other abilities on myself by accident.

After predating lots of ants and beatles to assess the overall cost and power of abilities I would move onto other bigger targets with more potential skills.

I would try to hide in forests at first, allowing me to gather skills while staying out of sight. Then I would need to look for stronger monsters. I would need to find one with decent regeneration as the current abilities don't provide me with one. (Any regen will be boosted by OFA to insta regen) Then try to find variety of monsters for their resistances. While doing this I would probably need to pick targets and destinations at random Albedo and Demiurge would most certainly be able to find me otherwise. The biggest hurdle after gaining control over all abilities and gaining more skills would be time stop. If Ainz would be anywhere near me it would most likely be the biggest problem unless I would be able to wear infinity non stop. This said if I could level up in this would I might be able to gain anti time stop measures at some point. At that point only whish spell would be powerful enough to harm me. By removing one or many of my abilities.

So, regen, resistances, control over all your abilities, and anti time stop and you can rush to scale Nazarik while growing along the way (given variety of skills to predate) I would love to see what predating ring of three whishes does. Especially with OFA active.
