Guild Wars 2

Quoting from the Cutthroat Politics New Features section:

“New World vs. World Ability Line – Catapult Mastery
This month’s World vs. World ability line addition is Catapult Mastery! Invest points in Catapult Mastery to increase damage done to walls, extra damage against other siege, increase your attack radius, and unlock a new, powerful skill.”

…and unlock a new, power skill.

Are the new skill batch coming out already and related to the Catapult Mastery somehow? Maybe it is just typo (or my reading comprehension sucks).

I would say it adds a new skill you can use when using the catapult, like a lot of the other siege mastery skills do.

New skill for the catapult’s skill bar.
