Put 1 on your starting board, in land #5.
You start with your 4 Unique Power Cards and 0 Energy.
Likes being in the same lands as Invaders, so it can use Range 0 offensive and defensive Powers. The first of its Innate Power can give some mobility, if needed.
Has a poor Plays track and potent but expensive Unique Powers, so can be better at handling fewer large threats than lots of little ones.
Devouring Teeth Lurk Underfoot Official FAQ Entries
Your Damage-Dealing Powers do +1 Damage.
(This adds +1 Damage total for the Power, even if the Power Damages multiple Invaders or "each Invader". It can boost Minor/Major Power Cards, too, not just your Uniques + Innate.)
SUMMARY OF POWERS
Long ago, the being which would become Devouring Teeth Lurk Underfood was a small, territorial Spirit of the sand-by-water. It waited patiently for small prey to approach, then frightened them towards its waiting maw; when fresh prey was scarce it would scavenge.
Most such Spirits stay tiny, but this one happened to take a bite out of Ember-Eyed Behemoth. It slowly grew larger and more mobile, slithering below the land's surface in a way impossible for normal animals.
