Block Tales Damage Calculator — Attack Stat vs Boss HP

Attack Stat Scaling Table

This table shows how your damage output changes at different Attack levels, assuming Defense 12 (mid-game average) and the stated card effects. Use it to decide whether a level-up brings a meaningful DPS increase or whether a buff card matters more.

Aggressor at 3.0× is the highest burst available but costs 4 BP and lowers turn economy. Power Stab at 2.0× is efficient at 1 BP, making it the best damage-per-BP card in most Chapter 1-4 contexts.

Boss HP and Defense Reference

These values are community-derived from gameplay observations across Chapter 1-5 clears. Block Tales does not display exact enemy HP during combat, so these figures are estimates based on observed hit counts and comparison across party-size variations. Use the damage calculator above with these numbers to plan hit budgets per boss.

Mutant is an optional Chapter 5 superboss and has the highest effective HP-times-DEF product. It is not required for chapter completion but is the best benchmark for a fully optimized damage build.

How the Block Tales Damage Formula Works

After completing all 5 chapters and testing builds across multiple party sizes, the consistent pattern I observed is: Final damage = max(1, (Attack − Defense)) × Buff multiplier. The minimum 1 floor means even under-leveled characters cannot deal zero damage to a high-defense enemy, which keeps the game from becoming completely unwinnable.

The formula matters most when choosing buff timing. A 1.5× buff applied to a base difference of 50 gives 75 final damage. A 2× buff on the same base gives 100. That gap compounds over a fight because you have a finite number of high-buff turns before SP runs out. Knowing the break-even hit count helps you decide whether Aggressor or a support card is the better BP spend on a given turn.

Defense scaling is non-linear in practice because the game rewards bringing Attack well above the boss Defense value. At Attack 150 against DEF 20, the effective damage is 130 × buff. At Attack 100 against the same DEF 20, it drops to 80 × buff — that is 38% less damage for a 33% lower Attack stat. Raising Attack above the defense threshold gives a disproportionate return, which is why Chapter 5 build advice consistently pushes toward ATK 150+ rather than accepting the mid-tier ATK 100 plateau.

Which Buff Cards Matter Most for Damage

Block Tales has three practical damage multiplier paths: Charge (stores a burst turn for 1.5× effective damage on the next attack card), Aggressor (3 BP net return on a 4 BP spend, equivalent to a 2× baseline multiplier on burst turns), and Power Rush (2.2 base damage for 2 BP, high burst but no defense contribution).

Charge is the most reliable multiplier because it does not consume extra BP — it converts a passive turn into a better future turn. Aggressor is the highest ceiling but requires a support plan because it reduces turn economy by -0.4. For bosses in Chapter 4 and 5 with high DEF, Aggressor only makes sense when your party can absorb the negative economy swing. For earlier chapters with lower DEF, the raw burst is less necessary and the economy cost is harder to justify.

The practical implication: build around Charge first, add Aggressor only after your support plan (Prayer, Bodyguard, Cure) is confirmed. A party that runs Aggressor without support coverage will win fast fights quickly and lose slow fights entirely. That variance is fine in Chapter 2 but dangerous in Chapter 5.
