This is how to farm Nolani Academy on Hard mode for Gold drops, tomes, dyes and more.
Doesn't need an elite:
Skills:
Sandstorm (e) - http://wiki.guildwars.com/wiki/Sandstorm
Crystal wave - http://wiki.guildwars.com/wiki/Crystal_Wave
Sliver Armour - http://wiki.guildwars.com/wiki/Sliver_Armour
Armor of Earth - http://wiki.guildwars.com/wiki/Armor_of_earth
Stoneflesh Aura - http://wiki.guildwars.com/wiki/Stoneflesh_Aura
Ward of stability - http://wiki.guildwars.com/wiki/Ward_of_Stability
Aura of restoration - http://wiki.guildwars.com/wiki/Aura_of_restoration
Balthazar's Spirit - http://wiki.guildwars.com/wiki/Balthazar's_Spirit
You can pretty much replace crystal wave with anything that isnt aoe DoT.
You need 16 Earth Magic - (12+3+1) and 13 Energy storage recommended (12+1)
The 16 Earth magic is VITALLY IMPORTANT. Have 16 Earth magic even if it means dropping to 12 or even 11 energy storage.
You also NEED an Enchantments last 20% longer weapon mod. If you don't have this the farm doesn't work
Cast Balthazar's spirit. This remains on for the whole farm.
Then go the the lever and cast Stoneflesh and Aura of restoration.
Run down to the middle and cast armour of earth, then Ward of Stability.
WoS means you can't get knocked down - this is to deal with Meteor shower.
Use sliver armour and Crystal wave to take them out in this order:
Boss
Flame wielders
Warriors
Rangers
The warriors have a special tactic, for Sandstorm - See video
Avoid using Sandstorm in normal combat, it will make the charr scatter. Only use it to deal with the warriors.
