Maybe you guys all know about dragon caves. 1 dragon, no big deal. But on one shard, there is a cave in which I found SEVEN dragons. I tried with lv30 archer and lv30 warrior, with paladins, knights, monks, Xbows. They cannot even kill one dragon before died. What can I do...I'm really curious about the reward.

Warrior can solo them with godly items.
Round attack + vampiric sword/ hammer with tireless + vampiric rings.

Another variant - strategist with tons of high level slingers. They have double shot and armor piercing, under strategist's abilities - around 30 damage to dragon each per turn.

Reward - 2 level 7 items.

Thanks a lot, though I really doubt that warrior solo strategy would work. Dragons intend to throw fireballs at the warrior instead of melee, and it seems really hard to boost magic resistance. Maybe keyword here is GODLY gears.
