A-tier

A cost-2 Power that negates the next HP loss entirely. It blocks HP loss rather than just damage, so armor-ignoring attacks, curse damage, and similar bypass effects all get shut down.

It functions as insurance against a devastating blow in boss fights. Even at 0 Block it shuts down a potential lethal hit and hands you another turn to recover. In Block-heavy builds like Frost, it acts as the emergency backstop when Block comes up short. Pairs with Loop strategies to stack Frost Block while Buffer stands by for the worst case.

• Use as boss-fight insurance against a massive incoming hit
• Works even at 0 Block, preventing total defeat in the worst case
• Install before a heavy-spending turn to survive the counter-attack
• Negates HP-loss sources (curses, Poison, Burn damage) in many cases

• Frost builds: Covers gaps when Frost Block comes up short, negating big damage that breaks through
• Dark builds: Offense-heavy turns often leave Block Weak. Buffer guarantees safety through the combo turn
• Machine Learning: Extra draw each turn keeps Buffer findable whenever you need it

• Obtained from Defect card rewards during a run
