Conclusion:
This weekend sale presents some interesting concepts but, undoubtedly, Arclight Varus is the one that stands out. A reinterpretation of Varus before the corruption takes hold and taints his pure heart is a wonderful idea that is very nicely executed. No Varus fan should miss this skin.
Below stands, or swims, Deep Sea Kog’Maw and this time he leaves behind all of his cuteness to embrace the monstrosity he actually is. The aspect is visceral, direct and definitely effective. It may dissuade some due to the absence of void puppy characteristics but those that like to rain destruction as Kog’Maw will find this skin quite attractive.
In the case of Junkyard Trundle the look is quite appealing as instead of going straight for trash it instead adopts a fitting wasteland style. The result is rather nice even if unspectacular so Trundle manages to impersonate a likeable post-apocalyptic mutant. While the remaining ice particles are a noticeable leftover the skin has good enough looks.

Conclusion:
When the time comes to avoid IP farming then there’s only one thing left to say: here comes Vi! Not only will she pummel her way through the opposition but she also covers a good gap of IP. Regardless, reserving RP for Neon Strike Vi wouldn’t be a bad idea. As it may take a while to go on sale so you may find yourself with enough IP to unlock her the old fashioned way.
Maokai may be worth purchasing depending on how much IP you usually gather but if skins are on your mind then there’s no need to rush. Haunted Maokai is his best choice and there’s ample time until Halloween, or Harrowing, to farm enough IP. If you’d rather save that IP for runes then now is a good time to prepare for such a date.
Finally, Sona really isn’t worth purchasing as her IP price is manageable. Considering the nice selection of skins she has RP is better spent there. Additionally, an eventual sale on Arcade Sona is to be expected but as she was discounted before the price changes chances are it will take a while.
