So are muspahs and nihils worth unlocking for tasks? and for block list i have jungle/desert/ice/warped creatures/ganodermic creatures/vyrewatch blocked , that sound about ideal for blocks.? I have glacors and tormented demons toggled on. Just curious thinking i want to get 104m slayer xp for true mastery cape 

Id keep the ganodermic creatures off block cause gano beasts are good exp :3

also yes id say unlock for task

Morvran does not assign warped creatures. He also does not assign jungles. Swap those blocks for tzharr and grotworms.

 

Muspah are decent xp and good money. Nihil are the best money-making non-boss (and probably including boss too) task at the minute. at the expense of slower exp.

guess ill be doing the plague's end quest here soon then because atm im using kuradal oh i also have mutated jadinko's blocked to

Muspah 200k slayer xp/h if you arent an bad
