The first suggestion is simple: the ability to toggle on bosses, for some of the bigger bosses i quite literally cant see my screen from the flashing white and having to disable the mod, reload, than fight a boss, kill it, enable, reload, its a bit much.

Suggestion 2: possible damage threshold needed to trigger the effect. X% of enemys HP done in a hit to cause the effect to trigger or possibly scale.

Final Suggestion: Possible cooldown for the effect as if your using a minishark is looks like a rave of flashing, me eyes hath perished.

These Are Suggestions And I dont expect anything to come of it, but wanted to leave it here anyway. (thanks for reading)
