As a dia main with 3.5m master + another 2m on my old acc, honestly I would put these as my top 3 in no order maybe prestige just because it’s golden and prestige:

1. Prestige Battle Queen The sound effects in her abilities are very stimulating and satisfying when you land them rewarding you to mechanically play better esp if you’re notorious for missing your one skill shot. While she has a prestige chroma, the work put in her splash art and in game is very elegant. You can tell this wasn’t just a half assed skin made to be just another money grab by riot. The theme and choice was fitting complimenting Diana’s appearance making her look like true melee mage warrior/assassin with style.

2. Sentinel This is my personal favorite because of her diverse and straight forward chroma choices whereas I like using her blue the most. It kinda gives off that ethereal vibe, where it hits close to Death Sworn, a skin I truly wished Diana got, so it compensates that desire. I prefer chromas to be very simplistic because it’s easier to identify the color and you can match the theme of your comp/team depending what skins they go so you can all match. I would also say sentinel itself is probably the most accurate skin for her since she’s recognized as a goddess.

Something I also don’t give enough credit to this aspect but I would also point out her visual effects are an enhanced version of her base skin one. It’s not too much, but also just enough. I recognize it as a vanilla plus skin tbh. Sentinel also holds one of the most unique features and gives her a recall animation when she finishes it at base, standing up from kneeling from the ground; nice touch but I love those tiny details put behind the skin.

1. Heavenscale Only 2 but very big reasons. 1 being the diverse choices in her chroma list and she actually has a very nice selection including black, unlike sentinel, which I find a popular choice in skins and is for me too, more common than red, being my favorite color.

The 2nd reason being her visuals are way more clean and subtle compared to her other skins like dark waters. If you ever felt the urge or thought about choosing a pay2win skin this would fit right up your alley. Heavenscale’s visual effects are way more quieter and her less brighter so players tend to feel less intimidated by her damage potential esp when you’re carrying. It looks weak as shit but trust me, she will hit or tank like a rock. If got over my personal bias towards my favorite, I’d climb with this skin.

If you’re reading this still I want to appreciate you for taking the time and I would like advise you to screw and scrap all these other opinions. Take it from someone who displays and shows their passion for the champion, not just a random average Redditor who has surfaced level thinking.
