Yesterday i farmed the obsidian Golem with two other volunteers and i have to admit that its better if one person is doing the Isturak Golems.
We made about 150 sparkstone in about 1:30, that can be done in 15min at isturak golems.
The Court of Trade just smelted all day long ore to provide it for a low price, also 2k repairshards and 1.5k Battlespikes has been donated so far.
I will keep buying ore and smelt it, here again as i said in my sticky post, EVERYONE WHO SMELTS 1K ORE SHALL BE GIVEN A REWARD OF 500g, its rlly boring and you dont gain much skill but it has to be done and 500g for watching TV is good enough
