Complete every single quest in the game, then talk to the wise old man at Draynor Village to obtain the cape.
You can't.
Speak to Pikkupstix in Taverly.
You cannot make a master skillcape in Runescape. You must buy it from an NPC by mastering the particular skill to level 99. The NPCs sell the cape for 99k.
no you just need to get to level 99 with that skill
There is no such skillcape. The only cape that comes close is the Prayer skillcape, which bears a similar icon to that of Saradomin; see the related link for details. Another cape that is similar (but is not a skillcape nor does it include any skillcape bonuses!) is the Saradomin Vestment cloak.
There haven't been any new skills in about like 2 years on runescape. Although it is confusing when seeing a magic, quest and prayer skillcape emote. They are all pretty similar. I don't know if you get a skillcape for completing achievements diary or not. Jagex announced that they are currently working on a new skill. They did not yet announce what the skill will be. Check the announcements on the RuneScape main page, and check your list of skills now and then in case you missed the announcement. NEW UPDATE: dungeoneering is the new skill. With dungeoneering you can get 120 of it! known as TRUE skillcape mastery
Firemaking, though it is very time consuming, it is officially the most cheapest skill cape there is available, only to Quest Cape ( Which isn't even classed as a skill cape ).
Yes, you HAVE to be member to get a skillcape of any type.
None. Skill capes are members-only items.
I'd say cooking or fletching, very fast compared to others. :)
Nothing, you just get to use them all. Also the skillcape emotes are unique, you can't have all of them at once because you can only wear one skillcape. So you can't technically have all of them. - iKnow iType --> aka ~1z Poison~ from Runescape.
The Skillcape of Strength is located in the Warriors Guild on the 2nd floor, past the heavy door. A person with a big battle axe will sell it to you for 100,000gp after you get a Strength level of 99.
