Im not sure what they go for on Red, but you can get all the casters Kromzek surveyor scope/Spyglass for clicky cooldown. The effect is annoying as shit, but you can click it off and it's better than nothing. Alternatively, you could spend a few hours farming the goblin fort in Warslik Woods and maybe get a couple Shrunken Goblin earrings. Sometimes they drop back to back, sometimes it takes hours to get 1. Multiple Grachnist can be up at the same time so clear the whole fort.
Edit: For clicky cooldown there's also the
Star of Eyes quest and it can be clicked from inventory by any class. It's really easy if you could find a porter for an hour or so. The ground spawns respawn in a few seconds so everyone could do it together. The range on the Star of Eyes sucks tho.
Enchanter can be the best puller your group could get. Even if you don't have very high CHA and don't want to risk getting a crit lull resist, charm pet, send pet into room of 4-5 blue mobs, spam pet back off, AOE mez, root, kill. An Enchanter/Cleric can dominate any dungeon in the game, and you have that plus 3 other people. SK really only outshines Enchanter on yellow/red mobs or unmezzable/unstunnable mobs.
