So uh, I just spent 2 hours writing a thesis on this topic while dark sea fishing in the background. Multitasking got me nowhere as the thesis sucks in quality so I scrapped it and tried to salvage some parts of it but quickly lost interest in doing so.
In short, negative synergies is limiting build diversity ( Not true you’re just disincentived to go fire+water or something like that). Take for example, Light + Shadow. Blinding sucks ye but if I were to run light I shouldn’t be discouraged to choose shadow as my second magic. Probably Equinox will have something to do with their interaction but rn it shouldn’t be just damage reduction, instead maybe like increase the potency of the blinding/color disorientating + damage reduction ( people who’ve ever been to the cinema can relate to this). If someone’s burning and I hit him with an ice cube the size of his body he should get heat shock.
That’s all for now, I’ll elaborate on this further since my morale crumbled like a 2-storey tall jenga blocks stading on a comedically small glass piece in an angry bird game.
