Mistermath's Card Ratings for Voyage to the Sunken City:

7/10

It turns out that this repeats until it hits 1 damage, making this extremely potent both by itself and alongside spell damage effects. The randomness is a downside, but repeated shots mean that it'll probably get what it has to get done done. Of course, this is a solid card in quest hunter.

if there 3 or more minions it does, did once on 2 minions for me

Does it cast three times?  It's unclear.  Could just cast twice depending on their implementation.

Scales so well with spell power.

3 cost that kills a single target 5 health minion, or could wipe an early low health board w quest proc? i like it.
