It says on the card that it will deal 2 damage to every figure within 2 hexes, my concern is that it damages the buildings as well(which i don't think constitutes figures).

I know in the lexicon it says figures are creatures, or buildings, but when was the last time you admired the figure of a building...

Respectfully,

Sir Nit-Picker

We're just going with game terms, not lexicographical terms.
In game terms a figure is a unit or building.
