Double tear is a build that feels a lot like a slow-motion version of building snowball items. It takes 30-40 minutes to see the payoff in this case, and then the build gets really strong.

The trouble is that if you manage to farm up this build, then chances are you could've dominated and won with a more fast-paced build long before then. I can't think of a single case where these ridiculously slow builds are viable in competitive play against a single-tear build or some other more conventional build.

It's a lot of fun, though. Rushing tear and going X/X/21 gets you a ton of sustain from Strength of Spirit. In most cases, you want CDR and magic pen, so 9/0/21, but the defense tree can be helpful too.

Masteries/runes/skill order included for Ryze but not the others. Actually, Ryze is probably the only champ I would consider double-tear on in a real game, and that's only if you finish Muramana or Seraph's and have luxury gold for a tear; you probably won't get a chance to finish the second one or even buy AAS/Manamune out of it.

That said, this is a lot of fun in bots... or it would be, if 85% of the games didn't end in 20 minutes and you don't even have a full tear yet. Le sigh.

PROS:
* A lot of fun
* Stomps hard after 40-50 minutes
* Mages can now hurt turrets
* Pigeonhole lots of champions into Ryze's power curve!

CONS:
* Not viable
* Seriously, don't play this in PvP unless it's custom with understanding and fun-loving friends

These champs have decent or better AP scaling and either like to auto-attack, or they have single-target spells to proc Muramana.

In most cases, these champions also have spammable spells to charge tears quickly and, in most cases, proc Lich Bane/Sheen/Iceborn Gauntlet.

That's all you need to make a Double Tear champ for the lulz (that is, as long as they're mana champions!). I could have missed a few more as well.

Also, Taric's reworked passive! zomg. Too bad it takes him a long time to farm up a Muramana and is stuck playing bot support. :(
