Now for Capricornus, I don't vouch you to solo it, though DNC can solo it.
Dnc can solo it but he needs his sword equipped for it to count.
Blu can solo jyestha really easily with a moderate eva setup and sudden lunges (even pre-sudden lunge). Just always have at least 1 shadow up to eat break, if you're not bringing the whm.
Capricornus seems to have differing AIs depending on the spawn. Some times he spams his 2 hr and some times he never uses it. My friend tried blu/nin eva tanking it, but the 2hr tends to wipe shadows quick and he builds resist to sudden lunge. Your best bet is to zerg it. Get some tp and set up a SC->MB and it'll be near death, throw another 2-3 spells out.
Tammuz, don't solo him, petribreath will get you killed. Easy kill w/ evasion set + stona though.
