Since I've been asked to weight in, i'll give you some advice.
Obtain the following-Arma/pernix, chaotic cbows
-Subj robes/virtus, chaotic staff or virtus wand/book
-Bandos/torva and drygores or dual chaotic rapiers
-Vip slayer tickets (I used about 150 getting to 104m from 23m)
-1k+ holy overloads
*Having t80 helps alot more than t70, and t90 melee is a very good investment
Block/Prefer listBlock-Desert wyrms-Grotworms-Nechs-Jadinkos-gargoyles-kalphites-Additional task if you have enough quest points
Prefer-ganos-muspah-airuts-aviansies-cele dragons-elves
-It is not worth extending tasks, skip any tasks that are slow or have very high numbers (ie 115 iron dragons)
-Slay kril/dks if you have boss task as them and/or need gp. Always try to have kree/kril or dks boss task to get bonus xp+reaper points.
-Have magic/range/slayer quick gear setups ready, with melee/magic as 1 and 2 since you will use them most.
-Use ultimate abilities, they are worth it but watch hp using berserk.
-Use bonecrusher whereever possible unless gp is an issue, spring clean all items mithril+
