Is there another planet core you can get? Keeping eros level at 0 means you can't access the wriggle map
EDIT: <rant removed, that last fight was very satisfying, lol> But still, severe difficulty becomes a real chore later on. Tons of grinding required, for me at least. Maybe I used my skill boosts poorly, and maybe trying severe on a virgin run isn't a great idea anyway.
Also, relatedly: Why does the stun effect c-skill never work in any meaningful fights? I hate that every boss in RPG games always has to ignore status effects and also ignore player status defenses (ie: stun effect c-skill).
Also also: You can't sleep before the final fight? Seems like a bug or an oversight. If you want to grind out levels and you're locked into the final fight event chain, Alcy refuses to sleep. If you need to refresh your energy, the only way I've found to do it is to start the fight event (which refills your energy), then after 30 sec of cutscenes you regain control and can press D to go back to the minimap to continue your grind. Frustrating. Hopefully Kagura can patch that...
