Seeping Strikes is a rare major card out of the Synergy pool. Statuses from your Main last 30% longer (Chill, Crumble and Distortion fill 30% faster instead).

You can take it once · it only turns up when your Main ability can actually use it · it can be offered for 0 of the 34 abilities.

Only one card can reshape that ability this way — this one, or Heavy Strike, Lance Strikes, Sweeping Strikes, Driving Strikes and Sundering Strikes. Take one and the rest are gone for the run.
