A Discord server at Level 1 Server Boosting has 100 custom emoji slots. Reaching Level 1 adds 50 slots to the standard allowance of 50, producing a total of 100.
These are upload slots, not a collection of ready-made emojis supplied by Discord. Server administrators use them to add images that members can use within that server. The standard allowance and boost rewards are separate from Unicode emoji, which are available across platforms, and from animated emoji access associated with certain Discord features.
Discord’s boost system has traditionally increased emoji capacity as servers reach higher levels. Level 2 raises the allowance to 150 of each emoji type, while Level 3 raises it to 250 of each type. That wording matters: Discord commonly lists static and animated emoji capacities separately, so a statement about “100 slots” can be misunderstood as either a combined total or a per-type limit. For the quiz’s standard server-emoji figure, 100 is the canonical Level 1 answer.
