I want to share a story of my second account’s first delve. It’s a low-ish level account (about level 80) with decidedly limited team options. I went to Hall of Guardians with Hero/Valkeyrie/Leviathan/Ishbala.
It was going sort of ok until the Witches’ Coven. My Leviathan turned to a frog. I didn’t have anything that dealt proper damage anymore (the hero was already dead, I think). Somehow that fight finished on Valkyrie smashing people with skulls.
I tried the boss fight, and it turned out the frog was actually useful to take the first silencing-on-skull-damage troop out of the way. Valkyrie skull-smashed the three other troops, but ended up dying, leaving me with a frog and Ishbala against the legendary. Of course, the frog got silenced at every skull. And the legendary kept getting more life just as the frog managed to skull it into single digits.
I should’ve taken a screen shot of the moment the legendary had 1 HP and the frog matched a skull.
Delve level 20 was the most intense battle I’ve ever had in that game. And it was won by a frog with 7 HP.
