Eclipse Codex Defeat enemies to fill the 40-Essence Vial. When it fills, battle pauses and three random cards appear. Choose one, place or cast it, and the hunt resumes. Your hero also carries two bonus ground defenses outside the six-card deck. Path tiles extend only from the glowing road end. Merge identical towers by placing one over another. Adjacent tower combinations create hidden synergies. Enemy defeats fill the shared Battle XP bar; each new Battle Level pauses the hunt and lets you spend an Upgrade Point on a tower. Only the Axe Tower can increase attack radius. Drag empty terrain to move the camera, pinch or use the mouse wheel to zoom, and tap β to recenter. Enemies that reach the cathedral remain at the front gate and keep attacking until defeated.
Tower Synergies Towers buff each other when placed directly beside one another — up, down, left or right. Diagonals do not count. Active links are drawn on the battlefield as a glowing thread, with a mote travelling from the partner into the tower being buffed, and a ring around every tower currently receiving a bonus. • Holy Water Infusion beside any tower — +42% damage, +22% fire rate, attacks become holy • Freeze support beside any tower — +30% fire rate, +14% range • Guardian support beside any tower — +22% damage, +18% fire rate • Dagger + Holy Water — +22% damage, attacks become holy • Clock + Holy Water — +18% range, +12% damage • Axe + Bone Pillar — +20% damage, attacks ignite • Whip + Rosary Shrine — +18% fire rate Bonuses stack, so a tower with two partners gets both. Select any tower to see exactly what it is receiving and from whom.
