Vault and enigma-style events are usually built around limited attempts or keys, which makes how you spend them matter more than how strong your account is overall.
Don't spend your first key impulsively
Take a moment to understand the reward structure before committing your first attempt — these events often have a visible reward track, and knowing what's ahead helps you decide whether to push further or stop for now.
Track diminishing or increasing returns
Some vault-style events get more rewarding the deeper you go; others front-load the best value early. Figuring out which pattern your current event follows in the first attempt or two tells you whether to go all-in or spread attempts across the event window.
Save premium keys for confirmed high-value moments
If the event offers both free and premium (earned or purchased) keys, it's usually worth using free keys to scout the reward structure first, then committing premium keys once you know they're going toward genuinely valuable rewards.
Coordinate with alliance-mates if the event allows sharing
Some vault events include alliance-shared components or bonus mechanics — check whether your event has one, since missing a shareable bonus is a common way to leave easy value on the table.
