Starbound needs to have at least one method of completely nullifying fall damage. I've come up with a few different options. 1. Make all four Environmental Protection Packs nullify fall damage. 2. Make only the final Cooling EPP Upgrade nullify fall damage. 3. Make a new final EPP tier that requires Solarium Stars and adds nullification of fall damage to the previous tiers' effects. 4. Make the nullification incremental. Add 25% fall damage reduction to the Breathing EPP and then add an additional 25% reduction to each tier so you end up with 100% fall damage reduction on the Cooling EPP Upgrade.
