A roguelite boss rush battle set-up - but easier. Heroes and sparks get unlocked as you go, depending on which room (read: battle) you choose. Battles are generated, but the player has the choice of which battle/objective/rewards they wish to prioritise/go for. You get 1 weapon skin at the end of a run which takes over 2hrs. The entire DLC simply involves doing re-runs to get additional skins and/or unlocking more sparks/heroes/skins/enemies encountered in order to up the completion percentage. You can choose your difficulty level, and on normal (average), it was no harder than the base game.

Too repetitive and random for me to want to do additional runs, given that there doesn't appear to be additional story/voicelines the more you progress. 1 run was enough for me.

It was quite alright until I found out premium mode had 9 separate levels to it. I ain’t doing ALLAT.

Pros:
The idea of turning a TRPG into a roguelike so you can't rely on your most powerful strategy and have to adapt on the fly, by coming up with new strategies and synergies you wouldn't have come up with otherwise. The ability to see rewards you will earn for beating a battle and being able to strategize around that as well.

Cons:
The absolute minimum amount of battles you have to do to 100% Tower of Doom is 100. You have to do 10 runs, each of which consists of 10 battles. Eventually, this will become tedious, doing very similar battles over and over just for one extra skin. This was such an arbitrary way to increase the length of the DLC. They could've made each run give two weapon skins for example. It doesn't help that the mid-boss is always the same and there are only 5-6 bosses that the game can choose for the final boss of each run. Each run isn't short either, each one takes at the very least a couple hours to complete, but this aspect is made much worse by the next con.

Which is the difficulty. For some unimaginable reason, the base difficulty of Tower of Doom far surpasses anything else in the game. Every enemy has as much health and deals as much damage as in the hard difficulty option except the numbers are cranked up to ridiculous levels. In this DLC the difficulty slider is absent, so you can't adjust it even if you wanted to. You have to retry some levels repeatedly until you either give up and choose a different level or play the level so perfectly you manage to win.

But the worst part is even if you manage to trudge through the boring, unimaginably challenging slog of doing a whole 10 runs of Tower of Doom, you still won't be guaranteed to have 100% completion. Because the completion percentages can come from random factors such as which enemies you've seen. You'd think that after 100 battles, you would've seen every enemy, but this also counts bosses, which you can only see after the end of a run. So if you're missing a boss, you have to hope that after the end of a run, you got lucky and were given the right boss. If not, you have to do a whole other run. And this is if you've kept track of the enemies yourself because the game doesn't tell you which enemies you still have to encounter or which enemies you're even able to encounter in the mode.

TLDR;
Tower of Doom is a boring, infuriatingly difficult slog which takes way too long to complete and whether you can 100% complete it is based on random chance.
