This unit gains the unique ability Scorched Earth after your clan Year 803 which allows Signy to burn an area for 3 months, increasing the Snake's Attack Power by 40% and decreasing any production in the targeted tile by 50%.
Starting at age 15 in Year 800, Signy will grow over the course of the game and gains new abilities. She increases in age every March. At the beginning of the game, Signy is armed with a staff which one end sharpened to stab enemies like a stake.
At age 16 in Year 801, Signy gains 5% move speed and can now attack at range, and gained a better weapon in form of a spear. Although, she is yet able to move through tiles without alarming enemies.
At age 18 in Year 803, Signy moves faster and can go through tiles with foes without alaming them unless she attacked first (similar to a Skirmisher). She also gains the unique ability called Scorched Earth, allowing her to burn an area for 3 months, increasing all Snakes' buildings' and all units' Attack Power by 50% and decreasing any production in the targeted tile by 50%. This ability has a 3 month cooldown. Signy must run to the center of a Tile to use it, and channel the ability for 5 seconds uninterrupted. This may be canceled and the ability does not go on cooldown.
