Ancient Sorcery of Serpentfolk

You duplicate a spell whose effect you can see within range. The targeted spell must be ongoing or, if it was instantaneous, taken effect since the start of your last turn. The target spell must be no higher than 5th spell level if it is on your spell list, or no higher than 4th spell level otherwise. The spell takes effect immediately as if you had just cast it, using your own caster level and statistics.

At Higher Levels. When you cast this spell using a spell slot of 7th level or higher, the maximum spell level of the target spell increases by 1 for each slot level above 6th.
