Bug Changes
While bug changes happen every patch, as TFT is a live service game, it will constantly update, and with it, things do fall into the cracks. Most bug changes are minor, but every so often, a bug happens that changes player perception. Over the past few weeks, players have been reporting that their shops were not functioning as they always do and have “low-rolled” a lot more than intended and also that the infamous “wave theory” where shops alter from round to round was true. After investigation, Riot Games did find a bug that was actually affecting shop odds, and it has been fixed in Patch TFT15.4. However, the jury is still out on whether wave theory is real.
BUG FIXES
THE WAVE THEORY WAS REAL SHOPS WERE BUGGED #LOWROLLGATE (well… kind of).

Starting with the major changes happening in this giant patch is a reclassification of the Fighter Champion Role. With Fighters having built-in omnivamp, items that provide this ability to Fighters have become obsolete, which has limited item-building flexibility. So, omnivamp is being replaced with attack speed, allowing items like Bloodthirster to find a new home. Also, Assassins have missed the mark as a Champion Role, so they are being changed into Fighters.
Prismatic Orbs
Prismatic Orbs do not show up in every game of TFT, but when they do, they are designed to be game-warping and, because of that, should put everyone in the lobby on their toes, as everyone gets an insane increase in power level when they happen. Except that not all Prismatic orbs are built equally. For players needing gold instead of items, the randomness of Prismatic orbs from player to player could doom a player to a bot four immediately. To change this, Riot is making a change so that when Prismatic Orbs drop, everyone gets the same outcome. And to show some transparency, the odds of each orb are listed below.

Star Guardian is the trait with the biggest changes in Patch TFT15.4. The vertical power of Star Guardian is a little too much currently, so Riot is pulling some power from the amount of Star Guardians on board and putting it into the individual champions of the trait. On top of that, Luchador is losing its immunity and Untargetability when proccing the trait and is gaining some healing as a survivability tool instead.
Riot Games
One-Cost
Malphite has been a little too dominant for too long. The namesake for the best reroll comp over the past couple of patches, it’s time to take him down a notch. However, Riot still wants Crew reroll to be an important comp, so the power is being shifted into Sivir.
Two-Cost
Like Malphite, Kai’Sa in the Supreme Cells reroll comp is overperforming a bit, so she is being nerfed in Patch TFT15.4; however, Janna and Vi are more viable in Patch TFT15.4 thanks to some buffs.
Three-Cost
Senna is seeing some adjustments to make her feel better to play. The problem that Senna has had is that she is too clunky on the battlefield, so her logic is being rewritten in hopes of making her faster, better, and stronger. Because of this, her power is being reduced as a preemptive measure.
Four-Cost
Rito Games
Riot wants to try to make the Heavyweight trait a viable vertical, so Poppy is being changed to have scaling damage to make her a good payoff for that. Ryze is being nerfed due to his presence in the meta game.
Five-Cost
Twisted Fate and Zyra are being adjusted to be better overall damage sources instead of focusing on the niche parts of their kits.
Esports Impact
The entire metagame is due to be uprooted when Patch TFT15.4 goes live as Star Guardian, Mentor and the Malphite reroll comps are being nerfed or adjusted in big ways. The Soul Fighter Samira comp, which is among the best performing comps in Patch TFT15.3 according to MetaTFT was not touched in a significant way so players may want to keep an eye on that comp. As for the Fighter changes, players will want to see if the change to attack speed opens up more fighter-centric comps.
