Special Abilities

Etch Symbol (Sp) When a father quill-legs starts a turn without an enemy within its tremorsense range, it takes a long step in a random direction and then takes a full-round action to etch a random magical symbol somewhere in its space (1d10): 1–4 5th level, 5–7 6th level, 8–9 7th level, 10 8th level. Father quill-legs needs no costly components for those symbols, but they fade within 1d4 years after being etched if not triggered earlier.

Grand Symbol (Sp) Trail of symbols left behind by father quill-legs is clearly some sort of grand magical working, forming mystical lines of some unfathomable arcane sigil, though it is near impossible to determine its potential effects until it is finished. The continental magnitude of this sign makes any imperfections and even removal of some of the constituent symbols irrelevant. Only changes and erasure on geographic scale could possibly interfere with such effect.

Long Step (Ex) Father quill-legs have legs far longer than the height of most giant creatures. When it takes a 5-ft. step, it can move up to half its speed (30 ft. normally). It can walk over most obstacles and difficult terrain without being hindered.

Trigger Symbol (Sp) Father quill-legs can take a swift action to trigger any symbol, glyph, or rune within 120 feet. It is never affected by its own symbols. This is an equivalent of a 4th level spell.

Father quill-legs is an enormous warmachine, a siege weapon that leaves a trail of dangerous magical symbols, creating an arcane border of sorts, following obtuse, and possibly corrupted instructions.
