[Entrapment Pact: Adds an imprint effect to the base crystal, increasing the summoning probability of summoned turrets by 15% and the number of normally summoned units by 2.]

...

Of the three runes, only the first one can have some effect on solar flares.

But it is also limited.

This defensive tower already has no shortage of damage.

As you can see, the damage output from each wave of solar flares is far beyond the strength of the monsters in the current wave.

The only drawback of this tower is its slow startup time.

Lack of energy.

Now, thanks to the boost from the infusion of the Holy Grail and the energy crystals, things are much better.

There's really no need for harm.

If possible, Su Bai would like to give this rune to the Frost Dragon. However, although the Frost Dragon's attacks have fire effects, they are actually ice-attribute damage.

None of these runes were worth his selection attempts.

Then I opened the card shop.

After glancing at it, Su Bai's lips twitched slightly. Clearly, this wave of card shops did not have the defensive tower he needed.

"Is this forcing me to choose the enhancement crystal?"

Three chances.

It can directly enhance the base crystal three times, which will trigger the second level of enhancement effect.

But it didn't help.

The current three-minute rest period is enough for his Holy Tower to recover its energy.

"Just consider it as increasing your health."

Su Bai shook his head slightly.

Two Holy-type defensive towers have appeared in this wave of shop updates.

Unfortunately, none of it worked.

It's an output tower.

Although each wave of experience compensation can upgrade the defense towers by many levels.

However, the seventh wave came far too late.

Take the damage tower at this point.

It's basically just for show.

Su Bai needs more support towers or control towers that can increase damage and slow down enemies.
