An enchanter could use his clothes to stop melee attacks. Bind spells can be used to prevent a person from moving osrs infernal cape. This can also stop their weapon from cutting them. If Crafting were expanded upwards, perhaps at higher levels, you could create special mage robes and then use them to enchant via Runecrafting or Magic.
I can't think of any other thing Jagex could add to justify raising the level to 120, but presently the skill is fully. It is possible to unlock items during the 90s. If they wish to add Mithril Dragons to your POH, a more extensive inventory and let you withdraw them quicker, or an instrument which explains more about Shooting Stars they may raise the limit.
Extreme Potions have a reputation for being true to their word and there is no need for anything more. If they decide to include an Elixir of Saradomin (Saradomin Brew plus something else, which heals better than Saradomin Brew and does not reduce stats), they have the option of adding it.
It doesn't need to be raised as there isn’t enough space. Oh my goodness. Jagex could be forgiven, and I might, if I am impressed, applaud Jagex's raising Constitution, Prayer, and Summoning up to 120 to include more content. But melee is sufficient, and Jagex will need to increase Magic and Ranging. What do you think OSRS Fire Cape for sale? Jagex is looking at raising the cap on skill. Should they?
