FAQ

Experimental Shells questions

What should a new player do first?

Pick one character slot, finish the opening movement practice, join the AoTR [PI] group for the stated +5% XP and +5% Gold, then redeem codes before you spend Spins. Upgrade Damage, Speed, and Control before you chase raids.

Does a Family decide the whole account?

A Family is a permanent passive and, at Rare and above, often a skill. You can keep more than one and switch from the loadout. A Legendary that matches your weapon is more useful than a Mythical you cannot play.

When did Update 5 release?

Public reports of the Roblox event listing put Update 5, called Spooky Season, at 31 Oct 2026, 16:00 UTC. The same reports say the listing itself ran until 7 Nov 2026, 16:00 UTC. The shifter, Vessels, and Freedom difficulty stay after that listing window.

How do Divine Perks differ from Mythic Perks?

Update 5 added Divine as a new rarity above Mythic. Player tutorials say they are forged from Divine Fragments dropped on Freedom difficulty, not pulled as a normal perk drop. Body can hold one without a capstone; Offense, Defense, and Support need that path's capstone.

Which Titan should I unlock first?

Attack Serum is the usual first shifter project. Colossal is the widest raid clear once you can enter its raid, and Beast Serum is the Update 5 project. Ackerman and Zoe are documented as unable to shift, so do not farm a serum on those Families.
