Goliaths require that you have done lots of RS gold quests and many battles that are arcade-style in a tower full with quest monsters. Something you might pick up as you've completed your quests in general, I'm thinking. To get the ring, there's a very nice free ring you can pick up through "A return to stone" (I think that's what the quest's title is).
It's located in TzHaar city, at TzHaar's birthing place. It's the fremmenik ring's bonuses, and an array of extremely nice reused teleports, as well as a combat bonus against the tzhaar. You can also get the Berserker ring, which offers the ability to increase your strength. Or you could purchase the explorer's band, which has alchemy spells available for free every day. Or you might want to purchase an Onyx ring that is infused at mobilising armies. Google that stuff if you want to know more.
Since getting hacked, I only have 10 m cash left. I've been working hard to make money, but I am looking to attend college as well, so RS will become the least of my list of priorities. My current fight for melee is: Helm of Neitiznot Amulet of Strength, Dragon platelegs Fighter Torso. I'm considering buying the Dragon platebody for more defence, or a DFS for defence, and str bonuses. Which one do you think I should choose and why? I do have 99 pros and a steel dragon in my dungeon. I could charge the shield. If you're planning to be slaying, you do not need def. Just pray prossy p8 and legs for prayer bonus, and pray to protect yourself from melee/(mage/range depending on the mission). Then, you can get fury or glory. Glory is preferred if you cannot justify spending 9 million on an amulet. Fury has very decent defence stats when compared to cheap OSRS GP the ammy.. With better stats that glory.. A lot of sals say fury is a must, but glory is almost identical to glory.
