Dreyfall

From BoardGameGeek:

Dreyfall is a 2-player strategy game of tactical combat and survival in a fractured woodland. Once, the creatures of the forest lived in harmony, guided by the magic of the Dreyshard, the great gem of the forest. When the Dreyshard was separated, its power plunged the land into chaos. Now, two rival factions battle for control, each guarding half of the Dreyshard within their home tree. To restore peace, you must defend your own stronghold while launching daring attacks to reclaim the lost shard from your opponent. Each turn, players make critical decisions about movement, attacks, and powerful abilities, exploiting a cyclical combat dynamic to gain a tactical edge. Mastering this dynamic is key to victory! The fate of the forest is in your hands-restore the Dreyshard and bring peace back to the land. -description from the publisher
