The temple of a conquering god, built up and shaped into a titanic body for its divine spirit to inhabit through the hands of the faithful crew. A coven of witches weaving life into their shared home, granting it gargantuan legs and sharp fangs. The necromancer lords of old burst from their crypts, crafting a bone behemoth of the ancient dead to scour the lands. An insect god from another world approaches the party and requests their assistance, neural pathways open and inviting, in protecting this world that it might at last live in peace.
Each magical mecha has at least three available positions: pilot, gunner, and engineer. On their turn, the pilot can either move the mecha or turn it up to 180 degrees, or activate special movement abilities like wings or drills, the gunner can either fire or reload one of the weapons, and the engineer can repair one system or recover the hull by one. Weapons can only fire at targets in a semicircle in front of the mech, unless they hit all adjacent. Movement system with speed higher than 1 can only move in a straight line, and cannot move less than their full speed. Multiple crew can work at each station, but there's no benefit beyond two pilots or two gunners to a weapon. Crew can move to other stations, but it takes one round if they were piloting or gunning.
Attacks hit automatically, dealing one hull damage and disabling one system as determined by 1d6. When Hull reaches 0, the mech is damaged beyond use. Each movement system and weapon has an equal chance of being hit (a mech with more than six systems would be excessively powerful). Whenever a mech is hit, the crew add their mech's instability to the impact of the attack, and try to roll that number or higher on 1d6. If they fail, their mech is turned by the attack to face, away from the attacker.
These craft are massive, similar in size to an upright castle. Any attack from one will completely obliterate a human-scale target, up to creatures like dragons or kraken which can manage survive one hit and deal some damage back. Any attack less than a dragon's fire or a siege weapon will deal no damage to any mecha, but invaders can attack the crew.
