Codes, quests, the market, raid chests, and trading after the prestige gate those systems use.
Spend them on the raid whose serum you still need.
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.
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.
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.
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.
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.
