アストロラーベ

Astrolabe is an Ancient relic that lets you choose 3 cards from your deck and transform each into a random upgraded card. Unlike Pandora's Box's full randomness, you pick which cards transform, so risk is more controllable.

Comparison with Pandora's Box

• Pandora's: Transforms all Strikes/Defends. No selection — total gamble
• Astrolabe: You choose 3 cards. Controllable but fewer transformations
• The transformed cards are pre-upgraded — a major Astrolabe advantage
• Astrolabe for stability; Pandora's for high-risk high-reward

Optimal Transformation Targets

1. Strike — weakest attack. Almost certain to upgrade to a better card
2. Defend — candidate when Block cards are abundant
3. Misfit cards — transform cards that don't match your build direction
4. Starter unique cards — character-specific starters if they don't fit the build

Expected Results

• Transformed cards come randomly from the character pool but are pre-upgraded, making them immediately viable
• Upgraded Common cards are often far better than Strike
• Upgraded Rare cards are jackpots
• Getting even 1 fitting card out of 3 is a solid return

Character Evaluations

• Prioritize Strikes, then Defends, then build-misfit cards
• Even if the transformed card doesn't fit your direction, upgraded card power often makes it playable
• 3-card transformation is most effective after Act 1 — smaller decks amplify its impact
• After seeing the transformed cards, flexibly adjust your build direction
