Continue doing Slayer as I am (skip most tasks, just do points tasks + Rune Dragons + Edimmus), and then switch to actual Slayer after my Edimmu pet. - Which should leave me with some excess points for X monster release after 200m
Or
Get 200m Slayer, then use the points gotten to attempt to get an Edimmu pet
#1 seems like the better option for long term money making/slayer rewards.
