Shadow silk hood at 72 dung?

Lol title, got it from a night spider? I binded it as i heard its good? what does it do and was i lucky or something or is it just normal to get it at this early lvl Edit: Should i unbind the Shadow silk hood and get katagon platebody as i had b4? because i bot solo.. Whats better to have, Shadow silk hood or Katagon Platebody, and i only use meele while botting

 

Do some trial runs, if you are getting beat up rebind a platebody.. if you can handle the damage well enough, use the hood because the hood will hide you from basic dungeon monsters and give you greater xp/hr.

 

...Melee equipment then.

Here's your info:
[ http://runescape.wikia.com/wiki/Shadow_silk_hood ]

"A player wearing the Shadow silk hood is invisible to any humanoids that are not mages, necromancers, or bosses.

The effects of a shadow silk hood.
Not only can mages and necromancers detect a player wearing the hood, but they can cast a spell that makes the player visible to all humanoids for a period of time. They will cast this spell immediately upon spotting a player with the hood. Seekers and reborn mages will also cast this spell upon engaging a player wearing the hood. The spell lasts longer if cast by a higher level mage and can last for a few minutes. The exception is skeleton mages, which can attack you but cannot cast the spell to render you visible. The spell looks the same as the Lunar spell Stat Spy.
When attacking a humanoid enemy from an invisible state, the player does not become visible to other humanoid enemies in the room. This means that it is possible to clear a room of non-mage humanoid enemies one at a time. Additionally, even if there are non-humanoids in the room that can see you, the hood allows you to kill these enemies first while the humanoids leave you alone."

Read the section "Binding" It should clear up some questions.
