I like how it’s implied that Eridan’s Wand of White Science wasn’t special, or even a true wand. It was his hope, his belief that it gave hime power which aloud him to channel his Prince of Hope powers so effectively. Kinda counterintuitive, but it really shows how powerful hope is if that power was all Eridan.

This is the same with Rose though- Both use their wands to channel powers, but are then shown to be able to cast spells without the device. It ties in to the theme of Aspect Powers and Powers in general being an inherent, indivisible, natural part of characters in Paradox Space. With Hope specially, this should be prevalent, as we all know, the main source of Magic is believing it is real, so the Prince determined to use Magic Science to kill someone in a fit of desperate rage, would certainly get a boost.
