QTE don't fit very well in a turn based combat game (or most games imo) but it does remind me of the spell-casting mechanic in some roguelikes, you have a rune tablet and depending of the different runes picked you can cast a variety of spells (the more recent example is probably legend of grimrock), is not a QTE but it has some of the difficult and rewarding aspects that Asyreon is talking about, probably a slow mechanic for this game and not something that i would like to see in it, but looking for new spells books is always a nice incentive for exploration and, if learning source magic is a really important part of the plot, it makes the learning process more tangible
