I consider Elona one of my main inspirations, along with ToME, Dwarf Fortress and some others. I liked the customisability of your character, all the wacky mutations, many ways of influencing the items (changing materials/making stuff +4 etc) and on top of that an open world with your own house/museum etc... On the other hand I played a fair bit of Dwarf Fortress, and I loved the damage system with all the limbs and armor pieces. Dungeonlike is meant to be (at some point in the future) a merge of my favourite features from these games, together with all the brilliant UI solutions that exist in ToME.
Did not play Tyranny though, might need to take a look. My idea for spell customisation was based fully on my experience with Elder Scrolls 3: Morrowind, but your description of what Tyranny achieves sounds very interesting. With respect to race customisation. I recall your comment from several months back with these suggestions, got this listed somewhere in "things to consider" list (which is a huge list...).
Hit chance for spells relies on spell power, so while your spells start hitting harder, they also pierce through enemy hex resist easier (that is defined by Intelligence stat + Concentration skill). I suppose you reached a level of power which left enemy stats far behind in the dust, which might mean I need to adjust some of this, especially for enemies later in the game. I might also introduce "partial resist" mechanic, as currently such "200 dmg crush" spell like yours either hits and kills the enemy instantly, or just misses entirely. There should be something in between I feel, or some additional layers of defense against magical attacks. Otherwise all bossess will be always wiped with ease by any mage character.
