How to beat Tunneling Twosome
The pair
Tunneler: 87 HP, paired with a Chomper at 60 to 64 HP and 2 Artifact.
Chomper: opens with Screech, 3 Dazed into your discard, then alternates Clamp for 8 twice with more Screeches. Its Artifact makes your first two debuffs on it fizzle.
Tunneler: Bites for 13, then Burrows: 1 Burrowed and 32 Block that does not clear at the start of its turn, then Attack from Below for 23 every turn from then on.
Breaking through all of that Block stuns the Tunneler for a turn, strips Burrowed, and restarts it at Bite and Burrow.
How to play it
The Chomper dies faster.
Open on the Tunneler during the two turns before it digs in, then either kill the Chomper while it burrows or crack the Block if you have burst.
Block 23 every turn once it is under.
At higher Ascension
- Ascension 8+: 92 HP, 63 to 67 HP, and 37 Block on Burrow. Ascension 9+: Bite 15, Attack from Below 26, Clamp 9 per hit.
Where it appears
Unlisted: it is in the game data with the Burrower and Chomper tags but belongs to no act pool, so it cannot be rolled on the map in this build. The Tunneler also fights alone in Tunneler; the Chomper pairs up in An Automaton Pair.
