Love is Patient

Starting at 17th level, whenever you cast a spell of first level or higher, you can instead choose to hold onto it. If you do so, this spell becomes far more powerful. Doing so, requires you to double the casting time of a spell, i.e. a spell with a casting time of one action requires one action to initiate it, and another action on your next turn. Doing so allows you to cast the spell as if you had cast the spell 2 spell slots higher up to 9 level. For example, if you cast a spell of 7 level and use this feature, you cast the spell as if it had been a 9 level while only expending the 7 level spell slot. This also forces any creature that makes a saving throw caused by this spell to be at disadvantage.  Any attack roll you make with this feature has an additional +5 to hit as well
