Guide for Persona Fusion Alert

A fusion alert or fusion alarm is an event that occurs in the Velvet Room. This new feature is exclusive to Persona 5 Royal.

Persona 5 / Persona 5 Royal - Fusion Alert / Fusion Alert Guide

The alarm causes fused persona to acquire new skills, have stats that are higher than normal, and max skill inheritance slots. Guillotine, Electric Chair, or using the same execution in succession produces an accident. Accidents, however, are also more likely to happen during fusion.

If you use the persona made from the alert as material, you can produce an accident. The result is a persona that gets even more points in its stats. You will be sent out of the area after an accident occurs.

When Does the Fusion Alarm Go Off?

The fusion alarm occurs randomly. One way to trigger a fusion alert is to defeat shadows in battle. This covers both battles occurring at the cognitive palaces as well as Mementos.

Another way to make a fusion alarm go off is to raise Chihaya Mifune’s Fortune confidant level. Upon reaching level 8, Chihaya will offer a contraindication reading that increases the chance of fusion alarms occurring.

What happens in a Fusion Alert?

In a fusion alarm, a persona made in a guillotine is indicated by a yellow color.

When you use this persona for execution, it results in a special “accident.” Repeat the execution to get higher chances of obtaining accidents. If you break the streak of accidents, for example if you perform guillotine and then do gallows next, the chance of getting an accident diminishes.

Fusion Alert Benefits

Below is a breakdown of benefits the fusion alert can bring to the Protagonist in the Velvet Room.

1) New and Odd Skills Obtained during Persona Fusion

Other than stats, you can also produce other accidents such as odd skills.

After the fusion is complete, the produced persona can get skills that it can’t normally learn. Each time this happens, the word “Change!” will pop up on each of the new skills it acquires. However, everything relies on chance, so if you plan on banking on this persona, be sure to save first. By making a save file right before the fusion, you’ll be able to re-roll for a desired combination of skills. Furthermore, you have the option not to opt-in the change of skills.

2) Additional Experience Boost in Gallows

Another effect of the alarm is experience boost. In an alarm, the treasure persona’s base multiplier of three becomes five. You can use this time to raise the level of the Persona efficiently.

3) Better Equipment and Stats during Electric Chair’s Itemization

Besides fusion, you can also produce better items when there’s an alarm going on.

Normally, when you itemize Jack Frost in the Electric Chair, you should acquire Frost Hood protector (the P5R version) with 110 defense, 20 evasion, and + 20 SP. Since the fusion alarm is on,  you will receive an improved version of the armor together with better stats.

4) Better Effects of Incenses during Persona Lockdown

Last but not the least, the effect of the incenses during a persona lockdown become more potent in an alarm.

Therefore, prior to a lockdown, make sure that a fusion alarm is running. You can improve the Persona’s stats more effectively with this method. For example, if you picked an incense with +2 Luck stat boost, it will be converted to a +4 Luck stat boost instead.

Persona Fusion Accidents

When there’s a fusion alarm, there’s a chance that you will acquire a different Persona instead. These are called fusion accidents.

They are similar to treasure personas since they have a preset of skills. If you acquire them by accident, you have the option to preserve them by updating your compendium.

Fusion accidents depend on chance. Using the same facility for the second time in a row generates a guaranteed fusion accident. When the facility finally yields a fusion accident, the alarm stops.

How to Stop the Fusion Alert

There are two ways to stop the alarm, one is by speaking to Justine, while the other is leaving the area after fusion. Keep in mind that you can’t continue to improve the Strength confidant while a warning is underway.
