All-Out Attack

All-Out Attack is an uncommon Silent attack that deals 10 damage to ALL enemies and forces you to discard 1 card for 1 Energy. The AoE damage makes it one of the Silent's strongest tools for multi-enemy encounters, as it can hit every enemy simultaneously for meaningful damage. The forced discard is a real cost, but in discard-synergy decks it can be turned into an advantage.

All-Out Attack is most valuable in Act 1 and Act 2 encounters with multiple enemies, where its AoE can dramatically swing combat in your favor. The discard is best mitigated by having a hand full of duplicates or cards you want to discard anyway — Tactician and Reflex both benefit from being discarded by All-Out Attack's mandatory discard trigger. Upgraded, the damage increases to 14, which is extremely high AoE damage for 1 Energy and makes it a serious threat in any multi-enemy fight.
