Sapphire Seed

You narrowly avoid stepping on a bright, sharp... seed? Its unmistakable color gives away that it's a Sapphire Seed! Weren't these incredible seeds supposed to be extinct!?

Legends say that consuming one can greatly amplify your endurance, but what if you plant and nourish it instead?

You ingest the Sapphire Seed and within moments your limbs feel more agile, colors sharpen, and you sense the souls of nearby foes.

Good thing you didn't step on it.

You scour the Overgrowth and find a pot with good aeration. Then, you trek around, searching for an untouched spot where light peeks through a cracked wall. Carefully, you reinforce the pot with bark and vine to camouflage it, fill it with loamy, nutrient-rich soil, and nestle the seed just beneath the surface.

Finally, you gather dew from nearby plants and pour it over the soil.

Grow big, little seed...
Unknowingly, the Sapphire Seed attaches to you spiritually.
Thankful of your hard work.

Which option to take

Plant, on a card you play every fight anyway: a Power you cast on turn one, or a cheap draw skill, effectively costs 1 less each combat.

Consume

Heal9 HPUpgradeA card

Consume only if the 9 HP matters more than a permanent energy source.

Plant and Nourish

EnchantA card with Sown

How it plays

Consume heals 9 HP and then lets you pick any upgradable card to upgrade.
Plant and Nourish lets you pick a card and enchant it with Sown: the first time you play that card in each combat you gain 1 Energy.
Sown fits any playable card that has no enchantment yet, not statuses or curses.
