How to Use Boulderoth
Boulderoth should occupy the stable middle slot: surviving pressure while contributing enough damage or tempo to matter. A strong pairing is Nocthollow, because it gives the lineup a different stat angle while Boulderoth focuses on HP. If the choice is between Boulderoth and Glayzer, start by comparing HP 37 against 35 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.
Strengths
- HP 37 is the page's clearest signal, giving Boulderoth a real battle identity instead of generic rarity value.
- ATK 19 is high enough to act as a tie-breaker when comparing it with nearby cards.
- The HP lead is large enough that Boulderoth should be chosen for that job, not as a generic filler card.
Weak Spots
- SPD 11 is the number to protect. Opponents that punish turn tempo can make Boulderoth feel weaker than its headline stat suggests.
- Boulderoth leans hard into HP, so it can be redundant if your team already has that same specialist role.
Developer Battle Read
Developer battle read: Boulderoth is a durable bruiser, not a blank epic card. Its HP 37 and ATK 19 point to surviving pressure while contributing enough damage or tempo to matter. The first teammate I would test beside it is Nocthollow, because that pairing reduces the pressure on SPD 11. I would compare it directly with Glayzer before spending duplicates, since that shows whether Boulderoth's HP lead is actually needed.

Avoid it when
Avoid forcing Boulderoth into teams that already have enough staying power but still expose SPD 11. If Nocthollow or another support card is not available, wait before locking it in.
Fusion note
Boulderoth can grow toward level 5 with a 50-point cap. The first meaningful checkpoint is around 11 total copies or points, so spend duplicates only if this durable bruiser remains part of your main battle plan.
- Durable Bruiser: use Boulderoth to surviving pressure while contributing enough damage or tempo to matter. This is strongest when the rest of the team is not asking it to cover SPD alone.
- Team shell: pair with Nocthollow when you want Boulderoth's HP to matter without sacrificing coverage on SPD.
- Comparison check: if Glayzer is available, choose based on whether your next fight needs HP or ATK more.
