TFT Radiant Items: When to Take One and Who Should Hold It

TL;DR: A Radiant item is an upgrade to one item, not an extra one. Take it when a unit you’ll keep fielding uses that item, and give it to whoever deals or takes the most of what it improves. Double the stat isn’t double the damage: a Radiant Deathcap over a normal one is about 46% more damage on a unit with no other AP, counting its AP and Damage Amp, and less on a unit that has some. So a new item in a free slot can beat it early, and once all three slots are full it’s the way to add more. The earlier it arrives, the more rounds it plays.

Worked examples are hypotheticals: sums on Riot’s numbers, not records of real games. Numbers link to the Riot notes that print them. Others come from the game data files, read November 4, 2026, which can lag behind Riot’s notes, so trust the tooltip in your game. What Radiant items are, and how they’re handed out, is on senseos.gg’s Radiant items and Artifacts page. This page is the decision.

Can you get a Radiant item in Set 18?

Yes, but not on demand. Riot’s Set 18 notes tune Radiant items in 18.1, 18.2, 18.4 and 18.5. These are the ways in that the notes and the game’s text describe:

Way in	What you get	How long it lasts
Radiantize Wisp, 18.2	8 seconds into combat, one random equipped item goes Radiant, by the game data files	Temporary
Coven cashout, 18.2	2 Radiant Thief’s Gloves (written “Radiant TG” in the notes), among other rewards	The game
Masterwork Upgrade	By the game’s text and Riot’s 14.5 notes, a choice of Radiant versions of the craftable items on that unit. The one you pick upgrades and comes off	The game

Riot’s 14.23 notes (November 2024) have the Masterwork Upgrade in Prismatic orbs. Riot’s Set 18 notes don’t restate that, so check your bag.

The game data files also list augments that hand out Radiants, such as Golden Gamble, Radiant Rascal, Quality Over Quantity and Pandora’s Items III. Riot’s 17.2 notes list Golden Gamble at 2-1, 3-2 and 4-2. A file entry isn’t proof that an augment is live, though: the same list still holds Radiant Relics, which 17.1 removed, and no later note found brings it back. Read what you’re offered. No Riot page printing the odds for any of these was found.

How much better is a Radiant?

Close to double on paper, and less in play. Riot’s 17.5 notes (June 2026) say it set Radiants at double their core version, then adjusted them because some stats multiply harder than others. Here are the numbers Riot has printed, with the game data files where it hasn’t:

Item	Stat	Normal	Radiant	Patch
Bloodthirster	AD and AP	18%	40%	18.2
Bloodthirster	Shield, share of max Health	30%	60%	18.2
Hand of Justice	AD and AP	18%	35%	18.2, 18.1
Hand of Justice	Omnivamp	12%	25%	18.5, October 27
Spirit Visage	Durability	10% (8% in the game data files)	18% (15% in the game data files)	18.4
Deathblade	AD	55%, by the game data files	100%	17.5, and the same in the game data files
Deathblade	Damage Amp	10%	20%	13.3 and 13.4 (January 2025), and the same in the game data files
Rabadon’s Deathcap	AP	55, by the game data files	100	17.5, and the same in the game data files
Rabadon’s Deathcap	Damage Amp	15%	30%	14.17 (August 2024) and 16.1, and the same in the game data files

Now run that through the holder. A stat adds to what the unit already has, so the same upgrade means less on a unit that’s already built. Damage Amp then multiplies with AP, by Riot’s 18.4 notes. For a hypothetical unit starting at 100 AP:

The unit holds	With a normal Deathcap	With a Radiant	More damage, AP alone	More damage, with Damage Amp
Nothing else	155	200	About 29%	About 46% (200 x 1.30 over 155 x 1.15)
40 more AP from other items	195	240	About 23%	About 39% (240 x 1.30 over 195 x 1.15)

Durability works the same way. On the working rule that Durability cuts damage taken by its percentage, a Radiant Spirit Visage on Riot’s numbers is 1/0.82 against 1/0.90, so about 10% more survival from that one stat, not 80%. No Riot page was found that prints that rule, and the durability and damage amp guide shows the sum.

So you aren’t getting a second item. On these sums, a damage holder deals about 39% to 46% more, and a tank gets about 10% more from that one stat.

When should you take one?

Run three checks:

1. Will a unit you keep use the item? A Radiant is still that item. Riot’s 16.1 notes place Radiants above artifacts, but a Radiant tank item on a board with no tank does little. If no holder is in sight, weigh the offer as raw stats.
2. How many rounds will it play? By the game’s round list, each stage from 2 on has 5 player rounds. Riot’s 18.5 notes place new augments at 3-2 and 4-2, and 17.2 has the same two rounds plus 2-1 for Golden Gamble. Up to the end of Stage 5, an item taken at each point plays this many:

Taken at	Player rounds to the end of Stage 5
2-1	20
3-2	14
4-2	9

3. Is a slot free? This one changes the answer most.

Here’s a hypothetical unit already holding one Deathblade:

Option	The sum	More damage
Upgrade it to Radiant	200 x 1.20 over 155 x 1.10	About 41%
A second Deathblade, in a free slot	210 x 1.20 over 155 x 1.10, if the two Damage Amps add	About 48%
40% Attack Speed from an item, in a free slot, when it has none	1.4 times	40%, from that one stat
A new item, with all 3 slots full	Something has to come off	Depends on what you drop

So if you have the pieces for a new item and a free slot, the new item can beat the upgrade, and a stat the unit lacks gets close on one line alone. Once the slots are full, an upgrade adds to that unit without taking anything off. That makes a Masterwork Upgrade or a temporary Radiant stronger late, on a finished carry.

Compared with gold or levels, no Riot number pricing a Radiant against an economy option was found. So use reasoning: count the rounds above, and ask whether the item changes those fights. The augments guide covers how to weigh an offer, and the slamming guide prices the fights.

Who should hold it?

The unit that deals or takes the most of what it improves. As a hypothetical, say your carry deals 60% of your team’s damage, a second carry deals 25%, and the rest deal 15%. A Radiant that lifts its holder’s damage by 46% adds this much to the team:

Holder	Share of team damage	Team damage added
Main carry	60%	About 28 points
Second carry	25%	About 11 points
Everyone else	15%, split up	About 7 points in all

Fill in your own board from the damage chart after a fight. The same logic picks a tank: a Radiant tank item belongs on the unit that takes the first hits, as the tank guide explains, and the sum says it pays most on the biggest health bar.

Then check what the holder already has:

Situation	The call
The holder lacks that stat	Good. The first of a stat adds the most. On a unit with no bonus AP, +100 AP doubles its AP. On one with +100 already, it’s 50% more
The holder already stacks that stat	Look at your second carry, or a different bucket in the damage guide
You’re choosing from a list of Radiants	Take what your carry already builds, then the bucket it lacks
Your line may change	Fine. A Magnetic Remover moves it, by the game’s text. Riot’s 14.23 notes (November 2024) drop one from every PvE round, and no later line changing that was found, so check your bag

What about Radiant Thief’s Gloves?

By the game data files, they equip 2 random Radiant items each round and use all 3 slots. So you can’t plan the build, and the holder takes whatever comes. The Radiants are 2 of 36 core items. As a hypothetical, say each is equally likely and the two always differ:

Items that would suit the holder	Chance at least one of the 2 does
6	31%
10	48%
18	76%

So put them on a unit that can use a wide range of stats, rather than a carry that needs one exact build. Riot’s 18.2 notes also fix Thief’s Gloves offering different items when moved to another unit in the same round, so moving them shouldn’t reroll them.

What about a temporary Radiant?

Radiantize is a Wisp, and Riot’s 18.2 notes put it at 3 gold. By the game data files it waits 8 seconds, then one random equipped item goes Radiant, and not for good. Three things decide if it’s worth buying:

• Does the fight last? If your fights end around 8 seconds, it does little.
• Which item does it hit? The text doesn’t say more than “random equipped item”. If it picks from all your equipped items, a carry holding 3 of your 9 gets it a third of the time, and 3 of your 6 half the time. So fewer items elsewhere means better odds on your carry.
• Is it worth the gold? 3 gold is one and a half rolls: “Reroll 2”, seen on the Reroll and Buy XP buttons in a patch 18.5 game on 29 October 2026, with Riot’s 17.2 notes in support. The Wisps guide covers how to price any Wisp.

Quality Over Quantity is a separate case, if you’re offered it. By the game data files, units holding exactly 1 item upgrade it to Radiant, which reverses the usual advice: you’d spread items instead of stacking them on one carry. Riot’s Set 18 notes don’t mention it, so check that the card is there before you plan around it.

What changes when Set 19 lands?

Riot’s schedule lists 19.1 for December 1, 2026, and warns that dates can change. The reasoning holds: an upgrade adds to what the holder has, the slot question stays, and rounds left stay a count. Riot’s 17.5 and 18.x notes show the Radiant numbers move often, so re-read them, along with the 19.1 list of who hands Radiants out. The Wisp sections are Set 18’s, since Wisps are that set’s mechanic.

What should you do with your next Radiant?

Your spot	The call
Your main carry uses the item	Give it to your main carry
It’s a tank item, and you have a main tank	Your main tank, on the biggest health bar
No unit uses it yet, and it’s early	Take it if the stats help now, and move it later with a Remover
The holder has a free slot, and you can also build a new item	Build the new item, unless the Radiant’s bucket is empty
All three slots are full	Upgrade. Nothing else adds to that unit without a swap
Radiant Thief’s Gloves	A unit that uses many stats, not your specialist carry
Radiantize, in fights over 8 seconds, with your items on one carry	Worth a look
Radiantize, in short fights	Skip it
