How do you get Tumblers?

The useful part is how many separate taps there are. Tumblers come out of the battle pass, elite training, the nurture branch, hollow battle interlink, exploration, quests, shops and chests. No single one of those is the Tumbler faucet, which means you are not forced into one repetitive loop to keep stocked. If you are already doing quests and opening chests while you explore, you are already collecting them.

The battle pass matters here because it runs a free track alongside the paid premium track. Tumbler rewards on the pass are not locked behind the purchase. The same holds further up the capture chain: Anipods are earned through standard gameplay rewards and in-game events, so the items you throw at Aniimo are not a paywall in either tier.

Practically, treat Tumblers as something you top up in passing rather than something you go shopping for. Elite training and hollow battle interlink give you a reason to run combat content you would run anyway, and the exploration and chest sources reward just covering ground.

Buying them with Glimmer

Shops sell Tumblers for Glimmer, and Glimmer is itself a gameplay currency rather than a purchase. You earn it from quests, daily tasks, events, elite training, boss battles, chests, puzzles, branch activities, the battle pass and the Holo Battle Simulator.

If you want to buy Tumblers in bulk, daily tasks and events are the most efficient Glimmer farm. Everything else on that list pays out, but slower. Clearing your dailies and whatever event is live gives you the fastest route to a shop stack.
