The Archmagi's Lament:

Once this spell begins, it cannot be willingly ended by the caster under any circumstance, and any attempt to work around this will result in horrendous consequences. If successful, and for a period of three sessions are elapsed, a contest will occur between a target nation and the caster, which may not be rerolled under any circumstance, using both’s highest stat; this occurs at the end of each session. For every successful cast, after the three sessions, one of the below bonuses chosen may apply (this goes for both sides), then the spell ends: - The nation suffers an abysmal civil war event, of which they suffer a -4 penalty on. - The nation has all districts or cities sacked, with the resources going no where. - The nation has 1d4 pops die. Once applied a penalty may not be used by the other side. At the end of the three session period, the caster suffers 20 infamy for every effect they successfully applied. This spell may be paid for in parts, with a minimum of 5 of the cost being paid for each session. Once any amount of magic is placed into this spell, it's casting becomes public automatically; any attempt to circumvent this will result in horrendous consequences for the caster. The cost of this spell increases by 20 each time it is cast by you during an era.
