Tempestis is a legendary durable bruiser built around HP 39 leading over SPD 15. The useful read is HP 39 plus ATK 29, so it belongs in teams that can use staying power while protecting the turn tempo gap.

Tempestis should occupy the stable middle slot: surviving pressure while contributing enough damage or tempo to matter. A strong pairing is The Singularity, because it gives the lineup a different stat angle while Tempestis focuses on HP. If the choice is between Tempestis and The Singularity, start by comparing HP 39 against 39 instead of choosing by rarity alone. When duplicates arrive, fuse only if this card is already solving that same battle job in your active lineup.

Developer Battle Read
Developer battle read: Tempestis is a durable bruiser, not a blank legendary card. Its HP 39 and ATK 29 point to surviving pressure while contributing enough damage or tempo to matter. The first teammate I would test beside it is The Singularity, because that pairing reduces the pressure on SPD 15. I would compare it directly with The Singularity before spending duplicates, since that shows whether Tempestis's HP lead is actually needed.

Battle Notes
Pick Tempestis when your team needs surviving pressure while contributing enough damage or tempo to matter. The signal is HP 39; the follow-up check is whether ATK is enough for the matchup you expect.
Avoid forcing Tempestis into teams that already have enough staying power but still expose SPD 15. If The Singularity or another support card is not available, wait before locking it in.
Tempestis can grow toward level 3 with a 25-point cap. The first meaningful checkpoint is around 10 total copies or points, so spend duplicates only if this durable bruiser remains part of your main battle plan.
