Terrain2

The Rubble-Field — a waste of shattered ferrocrete and broken hab-stacks, ground too broken for a titan to stride cleanly across.

A war-engine moving through the Rubble-Field must pivot to change its facing before it can move, and cannot re-declare its Ion Shield arc for free that round; it treats the field as difficult ground for the purpose of its stride. Infantry-scale fighters, by contrast, pick their way through it freely. It is the broken ground that lets a swarm slip around the very arc the titan cannot turn to meet — the surround made of terrain.

The Sacristan Forge-Shrine — a household field-altar hung with relic tools and the machine-cant of the Household's artisans, a place where a wounded engine can be blessed and mended.

A war-engine that ends its activation within 3" of the Forge-Shrine, and is not engaged in melee, repairs a single lost Wound — no more than once per game for each engine. The Shrine cannot raise a war-engine already taken Out of Action, and only friendly Knights fighters draw on it. A Sacristan working within 3" of the shrine adds one to its Bondsman repair roll, the altar's relics guiding its hands.
