Best of luck!!
In Project Babel related news (yes, I still need to figure out a name, and "officially" unveil the damn game), I've realized during my current redesigning of all the bosses that I've given almost all of them "channeled" mechanics. Or, mechanics that are somehow able to be interacted with.
For example, for the first sideboss, once you push past phase 1, he'll dive underwater for a couple turns, and then eventually come back up, attempting to splash the party with water, making them more vulnerable to elemental damage. Where as with the first major boss follows the idea of "3 dudes, figure out how they interact with each other" and one of them has the ability to resurrect the other two. However, it's not "oh they're dead and BAM NOW THEY'RE NOT HAHA SCREW YOU," but rather "X is channeling energy for something!" will be shown for a turn or two before the action actually happens. The point of this is to give the player a chance to prepare, or interact by maybe trying to kill this guy before that point is reached.
Yet, on the flip side, the players abilities all have an immediate pay-off. You wanna do this? Alright, bam, done. HOPEFULLY it succeeds in making the player able to properly identify mechanics as they occur, while still being somewhat unclear for people doing the fights for the very first time.
