Most things are the same, most notable changes are the Corporeal beast, Revenants and Spectrals in the wilderness, they drop spirit shields, 3rd age armour and PK armour now (zuriels vestas statius morrigans)
Also things like void, torso, defenders are now tradable, and we have a warrior guild where you can get the torso/defenders. Also Hunter is now available for everyone to train!
We have the shooting star distraction and diversion where you can mine a meteor that crashes in emps every 2h, you can get a dragon pickaxe with this. There are also a couple new items, like the Dragon hasta (one handed spear) and god wings (donator items).
There are a couple new slayer monsters, like mutant tarns (only way to get seercull), Aquanites (drop amulet of ranging), Ice wyrms in high wildy (drop glaiven steadfast and ragefire boots) and also Wilderness wyrms that drop dragon claws.
Jad is now solo minigame with the full 63 waves, and you can also kill chronozon kbd and chaos elemental for dragon platebody pieces.
You can now buy a Guardian angel for 1m in the monastery west of edgeville so you get saved if you die (you have to buy another then)
There is now also a new client (opengl) that runs on your graphics card, so you have less lag if you have a nice graphics card in your pc.
