Hey, great question! The lava modules are crafted 1:1, same as vanilla - no batch production here. Here's the design philosophy behind them: 🔥 Why these are alternatives, not unbalanced:
Same output - The lava recipe produces the exact same vanilla speed-module or efficiency-module. There's no special "lava-module" item, so it integrates seamlessly with the rest of the game.
Same material cost - Both recipes require 5 advanced circuits + 5 electronic circuits. The 5000 lava is an additional requirement, not a replacement.
Faster crafting (10s vs 15s) - This is the early-game convenience bonus. If you invest in lava infrastructure, you get a small speed advantage in module production.
Recycling/Upcycling stays balanced - Since the output is a completely standard vanilla module, any recycling loops work exactly as intended. No "lava-infused" items that could break the economy or create exploits.
In short: These are convenience alternatives for players who go down the lava-tech path - not stronger, just a bit faster to craft. Game balance remains intact! 🌋
