Gravemaw

Wave 50, 13K HP and 130 DMG

Gravemaw is BOSS - WAVE 50: HP 13K, DMG 130, SPD 4.2, $1,600 on the red header. The HP value is 13,000, printed on the pill as 13K.

It is the balanced row among the early red bosses. Titanhorn leans damage at 90 for $900, Boulderback leans HP at 8.2K for $1,200, and Gravemaw clears 13K HP and 130 DMG together.

Boss cards in the wave 50 cash band

Damage per dollar is 0.08 on Gravemaw, 0.04 on Wrecker and 0.03 on Skyreach, while Sailback reaches 0.10 at $1,100. HP per dollar is 8.1 here, 7.7 on Wrecker, 9.6 on Skyreach and 3.8 on Sailback.

Read together, those two columns make Gravemaw the cheapest card that is strong in both. Sailback is the damage ratio and Skyreach is the HP ratio, but neither carries both numbers at this price.

Wave 50: the middle of the boss ladder

Gravemaw sits between Sailback at wave 60 and Wrecker at wave 70 on the unlock schedule. Its 13K HP is 1.6 times Boulderback's 8.2K, and its 130 DMG is 1.86 times Boulderback's 70.

The next red card, Wrecker at 70, costs $1,400 more for 10K more HP and 25 less DMG. If the run needs a body that can absorb a boss wave and still hit, Gravemaw is the row the data supports; if it needs damage per dollar, Sailback at $1,100 has the better ratio with only 4.2K HP.

No variant, just the next red card

The index has no Juvenile Gravemaw. The red path is Titanhorn 10, Boulderback 30, Gravemaw 50, Wrecker 70, Skyreach 90, then Thornwake 110 and the 20-wave steps to Grovebreaker 250. The gold mini-bosses at 20, 40, 60 and 80 are a separate header.

Sailback at wave 60 and Snapshell at wave 80 are the gold rows between Gravemaw and Wrecker. Neither is a Gravemaw variant, and both print MINI BOSS instead of BOSS. They cost less and carry less HP, so they do not replace the red row.

The upgrade after Gravemaw is Wrecker at wave 70: 10K more HP, 25 less DMG, 1.2 less SPD and $1,400 more. That is an HP upgrade with a damage cut, not a straight replacement.
