72 Ascension Perk Slots
This mod ads additional Ascension Perk Slots so you have a total of 72. You can unlock the additional slots by a repeating research tech.
THIS MOD ONLY ADD THE SLOTS NOT THE PERKS!
If you want additional perks you can check out the mod: "Expanded Stellaris Ascension Perks"
If you think 72 slots are way too much, I mad an additional mod with 45 slots: 45 Ascension Perk Slots
I tested the mod and it should be backwards compatible up to Version 2.4 even if the launcher won’t confirm this. Furthermore the mod is save game compatible.
You don’t want to wait to unlock all the slots? Then you can use the Console-Command "research_technology tech_repeatable_ascension_perks", wait for 1 day and an additional slot will be unlocked.
