Strength: An attribute of programs and ice.

Strength is a number located on the bottom left corner of ice and program cards. Strength is what allows icebreakers to interact with ice; abilities on an icebreaker that affect ice cannot be used unless that icebreaker's strength is greater than or equal to the strength of the ice.

Negative StrengthEdit

Strength can go below zero.
