Inkheart

Inkheart is a Deathtrap level.

Description
The Inkheart is a mystery, an absence of something colossal, a gap that distorts time and space in its vicinity. Countless generations of scholars have devoted their lives to the study of this anomaly, and the most plausible theory so far is that the Inkheart is all that remained of a civilization that had manipulated the dream-material of the Ink until they destroyed themselves and left a festering wound in the void that still gorges out their own nightmares from time to time. This fortress is too close to the Inkheart... and the presence of darkness is the most powerful here.

Tier 2
Heat Ray Sentries increase their damage per second, so you might want to keep the targeted monster in their crosshairs. They can save you a lot of trouble on this map, where Tower Traps slots are very limited.

Tier 3
Imprisoned Golems will be your first line of defense on this map, where you will face multiple Bosses at the end of each wave!

Tier 4
This map only grants you Summoning traps and some special traps unique to this level. Tip: try to build as many kinds of the available traps as you can.
