Those are so difficult to kill now. They can still deal a fair amount of damage to players in full draconic with their more powerful attacks. Their fireballs don't do a lot of damage but drains power of the armor very quickly. The crystals have 50 HP which makes the old cryotheum florb trick (Throw 'em on the towers and they could destroy the crystal inside it) useless. I've found that AE2 matter cannon (w/ max damage upgrades) is still effective and can deal a one hit to those crystals even through a layer of iron bars or nether brick slabs.
I managed to defeat the boss the first time with TiC signalum crossbow, draconic chest, enhanced dislocator and wyvern helm/legs/boots after about 50 deaths, with every single item in my inventory enchanted with Soulbound.
I've found myself dying quite a lot even in full draconic. A good strategy is to use the advanced dislocator to escape swarms of projectiles because they drain the energy of draconic armor pretty fast.
And once you kill it it will only drop one heart, but of course you can get a ton of obsidian (draconium infused ones too!) and the chaos shards too.
