Tablet of Truth

"Decode"

• Lose 3 Max HP and upgrade 1 random card
• Repeatable. The Max HP cost increases with each use

"Smash"

• Heal 20 HP

"Decode" for 3 Max HP costs very little for a card upgrade, so the first use has excellent cost efficiency. If you have cards in the deck whose performance changes dramatically on upgrade, take advantage. The cost climbs on each repeat though, so overextending cuts deep into Max HP. Doing 1 or 2 decodes to upgrade key cards and then saving the rest of your Max HP is a balanced call in most situations.

"Smash" gives an immediate 20 HP heal. In a rough HP situation it offers stable healing without taking decode risk. If your deck's upgrade state is already sufficient, there is no need to force the decode.

• The first 3 Max HP cost is light. If any card in the deck transforms on upgrade, at least one decode is worth it
• The cost grows per use, so deciding when to stop matters. Weigh the remaining unupgraded key cards against your remaining Max HP
• Upgrade targets are random, so if your deck's unupgraded cards are mostly duds, expected value drops
• Max HP loss is a permanent penalty. Make sure you Retain enough HP to survive upcoming Boss and Elite fights
• 20 HP of healing is a large number. If the next battle is tough or the next Rest Site is far away, "Smash" becomes a strong option
