Split Form is a rare major card out of the Synergy pool. Your Main ability gains Multiplicity, adapting to whatever weapon grants it.

Take this when your Main carries your on-hit effects — every extra hit is another chance to land statuses. It also tags you for later Multiplicity synergies. Skip it if your Special does the real work.

You can take it once · it only turns up when your Main ability can actually use it · it can be offered for 11 of the 34 abilities.

Only one card can reshape that ability this way — this one, or Heavy Strike, Lance Form, Scatter Form, Fanned Volley, Twin Barrage, Rippling Form and Lance Covenant. Take one and the rest are gone for the run.
