The Glass-Goliath

Ecology
The Glass-Goliath is a towering, humanoid construct built by the Dust-Rider shamans. It is composed entirely of the razor-sharp, reflective glass from the Sea of Glass, held together by localized gravity fields and a pulsing Aether-spark in its chest. It is a brittle but devastating weapon of war.
Combat Mechanics
The Goliath's attacks deal both heavy bludgeoning and massive slashing damage. When it receives a heavy hit, it "Sheds" hundreds of glass shards in a 10-foot radius, creating difficult terrain and dealing 2d6 slashing damage to nearby creatures. It is highly vulnerable to thunder damage, which can cause its entire body to vibrate and potentially shatter. Its reflective surface makes it difficult to target with gaze-based attacks or light-based spells.
Loot
The core of the construct is a "Heart of Glass," a pulsing Aether-focus that, when used as a spellcasting focus, increases the DC of illusion and enchantment spells by 1.
