Music cape was achievable to me some time ago...
this is what was needed for it back in the day (taken from wiki):
- 65 Thieving to enter all of the different seasonal gardens in the Sorceress's Garden minigame.
- A champion's scroll. (Unlock "Victory is Mine" inside the Champions Guild Arena)
- 70 Hitpoints to enter the Zamorak camp in the God Wars Dungeon. (Note: You CANNOT boost this requirement.)
- 70 Agility to enter the Saradomin camp, as well as a rope to access the area. (Note: You CANNOT boost this requirement.)
plus visiting every place that has music and doing all quests that unlock new music (obviously)
doesn't seem too bad right? the hardest task in that list is probably the champions scroll, but i was lucky to obtain it while doing a slayer task pretty early on
but now..
i need a dark totem to get skotizos lair music (i have two pieces that took me way too long)
i have to do monkey madness 2 which has a obnoxious 69 slayer lever req that will take ages to level up to
must reach great olm in chambers of xeric (a nuisance)
and now with the release of inferno i have to get a friqin fire cape to get to mor ul rek and i have to even sacrifice it to unlock the inferno music
what is it with every new music piece there has to be a requirement to unlock the music?????
