Haha, no point. You can have 500 lobs, and you'd still die. If you have that low hp the dragon will breath fire on you before you eat, and kill you instantly. Get your skills up brother, it's worth it.
If you want my advice, i'd just drop the pure aspect. I ain't going to flame you, but tell you that pures are great when its 1 vs 1 in pvp but more than that they die quite quickly. Especially against mages and rangers. Just making a suggestion.
I really suggest you get them all to 40-45 instead. At those low levels the dragon will rip you apart. Also if you do decide to face the dragon with those stats, bring a way of teleport.
Uhm i am having trouble with figuring out the concept of rune crafting exp. When i make 3 air runes per essence, does that mean i get 3 x the normal exp per essence? Or normal exp, and just 3 x the finished air runes? Thanks in advance =D
