Next questions to open
The wrong upgrade can make an early run feel worse than it should. The right upgrade often does not look flashy, but it improves the next three fights immediately.
This launch-week page is built for the practical question first: what should beginners upgrade first if they want cleaner early runs instead of highlight turns.
Short answer: upgrade the card that changes the next few fights
In the first act, the best upgrade is usually the one that improves your immediate combat math. That can mean stronger front-loaded damage, a more efficient block card, or a key starter card that fixes tempo.
Beginners often upgrade the most exciting card in the deck. The cleaner rule is to upgrade the card you expect to draw often and rely on soon.
When to prioritize damage upgrades
Damage upgrades matter most when hallway fights are lasting too long, elites are becoming risky, or your deck lacks enough front-loaded output to punish vulnerable turns.
If your early fights already feel slow, a damage upgrade often prevents more HP loss than a defensive upgrade would.
- Prioritize damage when fights drag on too long
- Prioritize damage when your next route includes elites
- Prioritize damage when your deck has enough baseline defense already
When to prioritize defense or consistency upgrades
Defense upgrades become better when you are bleeding too much HP in normal fights or when your deck already has enough damage but poor survivability. Consistency upgrades also matter when a single improved starter card smooths the whole deck.
- Prioritize defense when hallway fights chip too much HP
- Prioritize defense when you already kill fast enough
- Prioritize consistency when one starter card upgrade improves many draws
Simple launch-week class rules
You do not need a full card database to make better early upgrades. Use rough class rules until the deeper meta settles.
- Ironclad: upgrade toward cleaner immediate damage or core survivability first.
- Silent: upgrade cards that make sequencing and tempo more stable, not just flashy payoff cards.
- Necrobinder: prefer upgrades that reduce early instability before chasing high-overhead Doom lines.
- Regent: early upgrades should simplify tempo before you lean too hard into Stars or Forge payoff.
