Pharaoh Card

Pharaoh Card reduces consumption of all skills by 30%. The reduction looks at the total SP before reducing. This means that using 2 Pharaoh Cards will not reduce consumption by 60%, and neither will using 4 Pharaoh Cards reduce it to 120%. Each addition will reduce on current SP cost. Let's say a skill costs 100 SP:
 * 1) 1 Pharaoh Card: 100 SP - 30% = 70 SP
 * 2) 2 Pharaoh Cards: 70 SP - 30% = 49 SP
 * 3) 3 Pharaoh Cards: 49 SP - 30% = 34 SP
 * 4) 4 Pharaoh Cards: 34 SP - 30% = 23 SP
