Greetings, Citizens of the Internet!

This blog post will be a bit different than my other ones, since it attempts to be a cooperative piece of work with you swell guys and gals. And with that, I'll get straight to the point:


It's awesome, we all know. But for those who are interested in the abilities and limitations of the game engine itself, this also provides a once-in-a-lifetime opportunity to push the limits and observe possible whacky interactions. Because 80% CD means that many abilities can overlap.

Luckily, U.R.F. is avaible for Custom Games, so it's not hard to check these for yourself, folks!

My general assumption for the following to-do list is that buffs/debuffs from the same source will not stack unless specified otherwise, only refresh. You're free to check that for yourself, though.

If you find some whackiness thanks to U.R.F., please comment it, I'll add it to the reported list ASAP. Whackiness is confirmed when I can recreate it or if 4+ people can confirm it in the comments. Just don't say "I confirm that", though, try to recall the situation where it happened.

List of possible WhackinessEdit

  • Will Disintegrate Disintegrate halve the CD from 0.8 to 0.4? Given the short CD, what happens when two Disintegrates are flung at two different near-death targets before one of them dies? 0 CD or 0.2 CD?
  • How do several Demacian Standard Demacian Standards in a line and Dragon Strike Dragon Strike interact?
  • Does Pix follows the last target of Help, Pix! Help, Pix! or... does he multiply?
  • Can Malphite join the Formula 1 when throwing Seismic Shard Seismic Shards at different targets?
  • Multiple Pillar of Ice Pillars of Ice... maybe even a Pillar in a Pillar?

List of reported WhackinessEdit

List of contested WhackinessEdit

List of busted WhackinessEdit

  • Duo Twilight Shroud Twilight Shroud seems to work like it's a single Shroud.
  • When you recast Pale Cascade Pale Cascade after all 3 spheres have detonated, you're back to the value of the first shield. Or, in other words, it completely reset.
  • Double damage with double Spirit Fire Spirit Fire? Nope.
  • Science is not that good enough in Runeterra to allow the existance of two Gravity Field Gravity Fields.
  • Yorick seems to be stuck with single-type Ghouls and no amount of WarwickSquare Urf meat and skin can change that.

List of confirmed WhackinessEdit

  • Riftwalk Riftwalk can't be casted for an unllimited amount of time since the mana cost will be greater than the maximum mana pool, which has priority over the reduced mana cost. This should stop being an issue once you have 1200 mana, though.
  • Kayle gains double bonus AS and +25% Crit Damage when Righteous Fury Righteous Fury is on. Make her your new ranged ADC if you want.
  • Command your own Summon Voidling Evergrowing Voidling Army now! And build AD and Banner of Command item Banner of Command when you're at it because Voidlings will love that.
  • Maokai's Sapling Toss Sapling Toss is not limited. Facecheck of Doom indeed.
  • Swain's Ravenous Flock Ravenous Flock deactivates automatically at some point since it raises in mana cost and will exceed the maximum mana pool eventually, which has priority over -100% reduced mana cost.
