FFVI Worlds Collide

First and foremost Paladin Shield needs to be removed from the shop list. Cursed shield is fine but Paladin Shield just negates 70% of all attacks in this game and there is no price tag you can put on it where it simply is not optimal to find it in a shop and grind the GP to buy 4 of them without shooting the economy of the game in the foot. 

For now, in a race setting, it may not be feasible to grind ~200k GP to get four of them depending on the game settings, notably the GP multiplier. Races can be done in probably 90-150 minutes in general, and even spending 10 minutes on it may be an overall loss in a race. It's possible that the defensive bonus doesn't help much if the player handles attacks with other methods, and Ultima isn't the only high tier offensive option. There's also the potential fix farther in the future where shop prices can be more than 65535; this would also solve the problem.

Basing the levels of the enemies on your party needs to go away, period. At least for bosses. You can't hand that level of control into the hands of your players or they will solve your game.

Given that it's an option, there's no reason to remove it. It's a great option for newer players, and for experts, it allows a clever player to get through the game faster without the solution being "to just grind" because there's a lot that can be done without grinding, and it's naturally faster to do it this way.

Even if you plan to add a tutorial of sorts in Narshe later, a Text Document or something in the actual site page would be helpful in the mean time.

Do you mean something other than the text document that's generated with each seed? Like, just a description of how to get each item, instead of making players look at the text file and spoil what they'd get for going to some location? I think such a document exists, but yeah, could be prudent to add a link to said document to the site itself; I think a link to it only exists somewhere on the Discord server.

One last thing before I forget, In Kefka's tower, there is a place you could soft lock the game. In the place before you fight Guardian and the Statues you reach a spot that you can't go back. If you have all three parties there then your stuck if you can't beat the bosses for what ever reason and dont have some form of the spell warp.

If you have all parties step off the switches, and then step back on to the switches, it opens the path back into the first half of the dungeon, so there's no risk of bricking the seed this way.

Kefka's Tower just slowed to crawl once I got there and i hope the answer isnt that I just need 3 useable parties to tackle the Tower.

Level scaling does help with this; it's possible to take level 3s in there and have them provide meaningful support, allowing your damage dealers to be attacking more consistently.
