Beam Cell
DefectAttackCommon
A free attack: 3 damage, 4 upgraded, then 1 Vulnerable, 2 upgraded. The debuff is applied after the hit. Because it costs 0 it counts for every effect that cares about cheap attacks or attack count.
When to take Beam Cell
A fine Act 1 Common for Defect decks that want a debuff before Sunder or Hyperbeam and a free attack for All for One. Upgrade it if it stays past Act 1, for two Vulnerable turns free.
