Get 70 Pray for Piety (Unless you can make enough for Turmoil)
Keep your defense at 75, get your strength to 90+, then get attack to 80 and get 80 Dungeoneering for a Chaotic weapon and finally go PKing at Edgeville for some fun.
That's personally what I'd do on that account.
Also if you do do this, don't forget to get 94 Magic for Vengeance.
Not many options with these stats.
