So, I was looking at the quickling and was stunned by its +50 to jump. I found that every +10 feet over 30 feet of base speed, a creature gets a +4 to jump checks, which makes me wonder, does this bonus increase if a creature has haste or expeditious retreat?
Thanks in advance.
yes
Haste specifically calls it out in its spell description.
Pretty cool, huh?
