  How do the characteristics of starspots influence the triggering of stellar
flares? Here we investigate the activity of two K-type stars, similar in every
way from mass to rotation periods and planetary systems. Both stars exhibit
about a hundred spots, however, Kepler-411 produced 65 superflares, while
Kepler-210 presented none. The spots of both stars were characterized using the
planetary transit mapping technique, which yields the intensity, temperature,
and radius of starspots. The average radius was $(17\pm7) \times 10^3$ km and
$(58 \pm 23) \times 10^3$ km, while the intensity ratio with respect to the
photosphere was $(0.35\pm0.24)$ $I_{c}$ and $(0.64\pm0.15)$ $I_{c}$, and the
temperature was $(3800 \pm 700)$ K and $(4180 \pm 240)$ K for spots of
Kepler-411 and Kepler-210, respectively. Therefore, spots on the star with no
superflares, Kepler-210, are mostly larger, less dark, and warmer than those on
the flaring star, Kepler-411. This may indicate magnetic fields with smaller
magnitude and complexity of the spots on Kepler-210 when compared to those on
Kepler-411. Thus, starspot area appears not to be the main culprit of
superflares triggering. Perhaps the magnetic complexity of active regions is
more important.
