How to get permanent 4 Star Units in TFT Set 12

Starting with Patch 14.18, Riot is adding a new feature to TFT: Permanent 4 Star Units. Here are the core rules:

• Requires 27 Copies (3x 3 Star)
• Works for every Tier, though anything beyond Tier 1 will require a lot of setup
• 4 Star is the maximum, you can't upgrade the unit with Moonlight Charm
• There is currently a bug that prevents you from changing items once the unit upgrades to 4 Star

The current champion pool for Set 12 is:

• Tier 1 -> 30
• Tier 2 -> 25
• Tier 3 - > 18
• Tier 4 -> 10
• Tier 5 -> 9

While Tier 1 and to an extent Tier 2 can be achieved with Pandora's Bench and Duplicators, if you ever want to reach a 4 Star unit in a higher tier, you will have to use either Polymorph Charms or Recombobulator.

Warwick

• 1 Star -> 45 AD and 700 HP
• 2 Star -> 68 AD and 1260 HP
• 3 Star -> 101 AD and 2268 HP
• 4 Star -> 135 AD and 3427 HP

Abilities of 4 Star units also have stronger base damage.

• Ziggs 3 Star -> 450 Primary and 225 Splash
• Ziggs 4 Star -> 600 Primary and 300 Splash

Worth the Wait + Overrolling

• Select Worth the Wait 1 in Stage 2-1
• Once you have 8 copies, place both 2 star units on your board and wait for combat start
• Roll down and collect as many additional copies as possible (Overroll)
• Can also combine Worth the Wait with Two Tanky instead of Overrolling

Pandora's Bench

• Select Pandora's Bench in Stage 2-1 or 3-2
• Scout and decide for a 1 cost unit that is completely uncontested
• Upgrade several Tier 1 units to 3 Star and roll them until you have your desired unit

Double Up

• You and partner can decide for specific Tier 1 units
• Use Rune of Allegiance to send 2 Star or 3 Star copies to each other
• Your partner can continue to find the unit you're looking for.

Normally you can't find a unit you already 3-starred in your shop, but there is way to bypass this rule. If you roll at a specific time when you teleport to the opponent's board, you don't own any units for around half a second.

If you roll during this timeframe, you will sometimes still find additional copies. This can be useful if you're missing only a few copies and have Duplicators ready to complete the setup.
