</>Common questions about Max Energy
What does Max Energy do in Slay the Spire 2?
Max Energy is a Slay the Spire 2 mod from ProjectMods that gives you effectively unlimited energy every turn so you can play every card in your hand without worrying about cost. Once you flip the Enabled toggle on, the mod keeps your energy bar topped back up to your character's maximum value as fast as you spend it. That means turn one looks like turn ten, X-cost cards scale wildly, and any deck you draft can fire off its entire combo every round. It's built for theorycrafting, flashy gameplay clips, and steamrolling fights when you want raw power over careful tactics.
How does the auto-refill actually feel in a fight?
Max Energy keeps your energy bar pinned to its maximum throughout every Slay the Spire 2 combat. The moment you play a card and spend energy, the ProjectMods mod refills it before you can even notice the dip, so the bar always looks full whether you're on card one or card ten of the turn. At the very start of a brand-new run, before the game has fully set your character's energy stat, the mod falls back to a sensible 3 energy — which matches the default starting energy in Slay the Spire 2. Refills happen continuously, not just at turn start, so mid-turn spending is restored immediately.
Does Max Energy break X-cost cards and energy-scaling effects?
Yes, and that's part of the fun. X-cost cards in Slay the Spire 2 read whatever energy is available at cast time, so with Max Energy active they'll dump your entire energy pool into a single massive effect. Same goes for cards or relics that scale damage, block, or other effects based on energy spent — they'll all hit their ceiling. The ProjectMods Max Energy mod doesn't tweak card text or scaling formulas; it just keeps the energy resource topped off, so anything that reads from that resource gets the upgraded value. If you want X-cost cards to stay balanced, just leave the Enabled toggle off for that run.
Does the mod raise the energy ceiling, or just refill what I already have?
Both, actually. Max Energy doesn't just keep refilling to whatever cap the game thinks you have — when it tops your energy back up, it also lifts the combat's current energy ceiling to match. That matters in Slay the Spire 2 because some effects clamp energy to a per-combat maximum, and without raising that ceiling the refill would cap out lower than expected. The ProjectMods mod handles this automatically, so the energy bar genuinely shows the upgraded value rather than being silently capped. The practical result: whatever maximum energy your character has at the start of a fight is what you get to spend every single turn.
Can I turn Max Energy on and off mid-run, or does it have to be set at the start?
Max Energy uses a single Enabled toggle that takes effect immediately — no need to restart the run or even leave combat. Flip it on mid-fight and the moment you spend any energy, your bar snaps back to full. Flip it off and the ProjectMods mod stops topping up the energy, so Slay the Spire 2 takes over again and energy starts behaving normally from your next spend. That makes it easy to use the mod situationally: run a tough boss with it on for a power fantasy, then switch it off for the next fight if you want the regular roguelike challenge back. The toggle starts off by default.
