Base Shield Buckler,
Tower Shield
This surprisingly weighty, though well-balanced, wooden
buckler is emblazoned with the image of a sapling. The sapling withers as the shield takes damage.
Activate [one-action] envision;
Effect The buckler expands, with the sapling image growing into a mighty oak tree. The buckler becomes a
tower shield, gaining the corresponding AC bonus, Speed penalty, and ability to
Take Cover. It keeps the same Hit Points and Broken Threshold, but its Hardness and Bulk increase by 2 in this form. The shield remains in this form until you Activate it again to revert it to a buckler.
