Thanks for the best wishes and support, everyone, I highly appreciate it!
I've decided to put a hold to my Slayer grind and commence it in 2019. I'm going to perpetuate skilling for the rest of 2018 and prepare myself for the long grind, as well as bossing, which is going to be challenging for me with having only 1 Defence and no over head prayers.
I'm currently smithing bulk iron knives, as I have decided to get my Ranged level to 99. I'm also going to try and consummate more achievements, as well as get some quests out of the way before 2019.
Stay tuned. :)
