|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.
Strength can go below zero.
