Elminage Gothic's final bonus dungeon. Here's what you're up against:
* 20 dungeon levels, each, I believe, as large as a level from Wizardry 1 (which had only 10 dungeon levels for the *entire* game).
* The teleport spell does not work. There are shortcuts to levels 5, 10, and 15, at least.
* The encounters are downright unfair at times. For example, there are some archer enemies which get something like 2 actions per round, each of which includes 4 attacks for something like 300+ damage each, and which are much faster than your characters can possibly be. That enemy isn't even as strong as a similar enemy appearing later in the dungeon. This enemy (which often appears in groups) has been known to wipe out high level parties.
* Resurrection has side effects; it ages the character and lowers Vitality. Reloading a save also has side effects; your party will age a certain number of days each time, and the level will reset, causing placed encounters to respawn.
* The game actually expects you to reach about level 400 by the end (and you will likely enter the dungeon at double digit levels); even at such levels, the game can and will kill you.
(At least this dungeon isn't difficult to navigate, unlike some other dungeons in this game.)
(Also, at least I don't remember being teleported into solid rock; in the first floor of the first bonus dungeon, I had a certain enemy ambush my party and teleport everyone into solid rock, which causes the entire party to be lost forever; reloading is the only reasonable course of action in this situation.)
Leroux: Owlboy/Cave Story/Super Panda Adventures - I'm stuck on some boss battles halfway through.
I've beaten Cave Story, but not the bonus dungeon because of the boss fight at the end where the camera rules change (the camera follows the boss instead of you).
Cavalary: Final Fantasy 8, definitely not leveled enough for the final area, when stripped of all skills for that first boss fight there was absolutely no way to win with just regular attacks, tried dozens of times, even plenty of luck on the RNG still got me nowhere, and I had no intention of returning through the gates to grind, so just watched the rest on YT.
Haven't played it, but my understanding is that you can still junction spells to your stats and use those to kill the first boss there; it's a better choice than leveling up (and you can leave the final dungeon to draw more spells). Once you kill it, you can get some of your skills back (the choice you make should depend on your play style and what you've found to be useful).
Leveling up might actually be counter-productive.
DadJoke007: Every true roguelike except Tales of Maj'Eyal No shame in not being able to beat roguelikes, the only one I think is going to keep me motivated all the way through is Tales of Maj'Eyal. It might not be today, it might not be in 10 years, but one day I will finish it.
You can try roguelikes with meta-progress mechanics, like Tangledeep or even Shiren the Wanderer.
Or, of course, some of the other Mystery Dungeon games (like Pokemon Mystery Dungeon) technically qualify as roguelikes (albeit without permadeath), but are much easier.
DadJoke007: Every bullet hell out there 1CC, the only true way to beat them (one credit clear) How I've tried to achieve 1CC in all kinds of bullet hells, and how I've failed miserably. It's rewarding as all hell to strive for, but it feels unrealistic to actually achieve this goal.
The idea is this:
1. Practice.
2. Beat the game using continues, and then try to beat the game with fewer continues each time, until you get the number of continues down to zero.
3. If the game has a practice mode (Crimzon Clover does, for example), take advantage of it, and practice the parts where you find yourself losing lots of resources.
(I haven't beaten a game of this type, but then again I haven't made any serious attempts. (Well, actually I beat Jamestown on a laptop that couldn't run the game at full speed, if that countes.))
