[3.15] The Rainbow CoC

This post is not a guide. This build is definitely NOT a good league start, it was made for memes.

This build is about throwing through the Transcendence for maximum “visual clarity”. It was supposed to be just a meme. But then – by accident – it also became my strongest creation yet. It can clear the entire endgame AND reduce frame rate with incredible efficiency.

But why is this build a meme?

New Transcendence MTX is pretty dope (video). Interesting fact about is that every projectile that passes through it will retain it’s visual “burning” effect. So when used with the new MTX it turns most projectiles into rainbow spit. After testing multiple skills I discovered that gives the best, most eye-melting results. Here is a short clip of how it can look:

So after discovering this I decided to go all-out and cast as many as possible. But it turns out that has a pretty slow cast speed. If I wanted to spam it as much as possible I needed to use . And to maximize projectile memes I decided to go with as the trigger.

But why is this build not a meme?

To reach the highest trigger rate possible I needed at least 53% CDR (if you don’t know why, check out this post). To reach this high of a number I needed to use a Shaper influenced belt and boots – both of them have CDR mods that can push above 53% CDR.

So now build used both Cold and Fire damage AND two mandatory items were Shaper influenced – it started to smell a lot like . Not only that, but it turns out that you can get a Shaper influenced for cheap on the market. And if you don’t know – there is a very broken interaction between , and that pretty much doubles ‘s damage for single target.

It was at this point that I realized this build might actually slap. Turns out that throwing 10 each second can actually cause a lot of damage – to your target, your retinas and your GPU. And this is exactly what I wanted.

miscellaneous notes

  • It’s important to make it so that has a longer range than . This is because is most effective at maximum range, while needs to go past it’s target to deal it’s full damage. This can be achieved by modifying projectile speed. In my case I had to use and Anomalous version of the to get proper ranges.
  • I used Assassin for this build, but that’s not required. I’m pretty sure Occultist or any Ranger ascendancy could pull it off.
  • If you are having trouble reaching 53% CDR breakpoint remember that there are CDR mods on abyssal jewels.
  • also deals decent damage. You can take advantage of it by taking Mana Leech from attacks to sustain mana.
  • To reduce mana cost of you don’t have to use . Non-Channeling Skills have -# to Total Mana Cost mods for jewelry and are usually enough. There is also , which reduces skill cost.
  • Trigger a Socketed Spell when you Use a Skill mod’s cooldown is affected by CDR. Since this build stacks CDR you can put most utility spells into weapons and have nearly 100% uptime on all of them. Also – it’s less clicking.

  • As base we want for good balance of attack speed and crit chance.
  • We want both knives to have more-or-less the same crit chance (I messed up and so is scuffed).
  • Both daggers should have Trigger a Socketed Spell when you Use a Skill mod. Pretty much all utility spells are triggered this way in this build. Keep in mind that 8 sek cooldown is affected by CDR (which we are stacking), and it applies to each socketed spells separately. Also since triggered spells consume mana now you can put lvl 8 into one of the weapons for high buff uptime.)
  • For big dps increase we want Non-Chaos -> Chaos and Elemental -> Chaos conversion mods.
  • Accuracy enchant is pretty nice for reaching 100% hit chance.


  • We want Shaper + Warlord double influence for the mandatory +1 to Maximum Power Charges mod.
  • 30% reduced Spectral Throw Projectile Deceleration – This enchant isn’t necessarily required, by it makes reaching max trigger rate much, much easier.

Body Armor

  • is the core of build’s dps scaling.
  • Gain #% of Elemental Damage as Extra Chaos Damage per Shaper Item Equipped needs to be perfectly rolled.


Nothing special here, could make better ones with double influence. Pretty much all conqueror influences have some good mods on gloves.


  • Only required mod here is #% increased Cooldown Recovery Rate.
  • You have Tailwind if you have dealt a Critical Strike Recently provides big dps increase.


Only required mod here is #% increased Cooldown Recovery Rate. Ideal base would have been .


Needs to have:

  • Non-Channeling Skills have -# to Total Mana Cost – coz eats mana.
  • anoint – we can’t really reach it naturally, so we need to anoint it.


  • – Required for the + combo. Needs to be shaper-influenced.
  • needs to have Non-Channelling Skills have -# to Total Mana Cost mod.
  • Shaper influence also opens Adds # to # Cold Damage against Chilled or Frozen Enemies prefix, so get that if possible.


  • – Required due to the Non-Channelling Skills have -9 to Total Mana Cost mod, pretty much mandatory for builds in 3.15.
  • – Required for the keystone.
  • – with the +# Life gained for each Enemy Hit while affected by Vitality mod. This is our main source of recovery, it can top us off instantly.
  • Other jewels can fill life, mana and damage stats.


Nothing special here – life + utility flasks. can be easily replaced, for example by .
