How to beat The Insatiable
- You must win within 4-5 turns or the Sandpit kills you. Build your entire Act 1-2 deck around burst damage. Keep your deck small (around 20 cards) so you reliably draw Frantic Escape cards when you need them. Don’t play too many Escapes early — each one costs energy that should go toward killing the boss. Play Escapes only when the timer is critically low.
- Keep your deck thin (around 20 cards) to reliably draw Frantic Escape
- Don’t play Escapes unless the Sandpit timer is critically low
- Every Escape played is energy NOT spent on damage — balance carefully
- Front-loaded burst decks are essential; slow scaling decks will get devoured
