Having enemies with random sets of triggered effects that can help you, harm you, make that enemy stronger, or buff other enemies is an interesting idea that feels like it has a lot of potential. And having a party of allies with those effects adds a lot of potential depth. But in actual execution you can trivially outpace enemy max health via damage gain, one shot everything, and just not take damage.
To add some challenge, it probably shouldn't be possible to boost your health and damage arbitrarily high. Probably buffs should have a limited duration and/or reset between floors? Things which prevent the player from fighting enemies one at a time like ranged attacks and enemies which are faster than the player would probably also help.
Also, it wasn't too hard to figure out what was going on, but the game could really use some help text to explain the systems, especially what the different letters for the ally/enemy abilities mean.
