Im 39 slayer and level 95, which master should I use?

 

EDIT: which monster best drops crimson charms?

considering your lvl and you need as much exp as possible i would go sumona imo 8-)

I used Chaeldar for awhile.

i like chaeldar better.

new question at top.

Sumona's tasks are slightly harder, but she gives more tasks that can be cannoned to speed up experience rates.

 

 

 

Chaeldar's tasks are overall somewhat easier, and except for Bronze Drags her tasks are overall more "fun" than Sumona's. (By fun I mean that there are fewer tasks which make you groan and abandon the idea of slayer for a month or two.)
