Ice Fist

Increasing Ice Fist level raises the focus cost, but lowers the fizzle chance.

Water Attunement affects the damage, move rate penalty and duration, attack speed duration, and dexterity penalty duration.

Stacking and charging glyphs improve the focus cost, damage, move rate penalty and duration, attack speed penalty and duration, and dexterity penalty and duration.
