Sapphire Seed

"Eat"

• Heal 9 HP. Upgrade 1 random card

"Plant and Grow"

• Enchant 1 card with Seed-Sowing

"Eat" gives you 9 HP healing and a card Upgrade at the same time, making it a steady pick. HP management is tight in Act 1 and healing is precious, and if you pick the Upgrade target well you instantly increase deck output.

The Seed-Sowing enchantment from "Plant and Grow" adds an effect that heals HP whenever the card is played. Attach it to a card you play every turn and the healing accumulates across every fight, ending up well above the 9 HP heal. If you value long-term return, this is the better option.

• If your HP is fine, "Plant and Grow" has the bigger long-term payoff. Seed-Sowing heals in every combat, so total healing grows as the run goes on
• On the other hand, if HP is rough and the next fight is scary, "Eat" has the immediacy. Act 1 often runs long between Rest Sites, and 9 HP here can be the difference between living and dying
• To maximize Seed-Sowing, attach it to a 0-cost card or a card you are guaranteed to play every turn. Putting it on a rarely used card wastes the effect
• The Upgrade target should be either the most-played card in the deck or a card that gains a lot from being Upgraded. Cost-reductions-to-0 and big scaling buffs are the top picks
• If Seed-Sowing covers your healing needs, you can spend Rest Sites on Upgrades instead, which indirectly strengthens the deck as well
