I also have this problem....am on warrior though and am running out of energy. Regen skill and patron skill dont help much...problem for starts when the winged demon spawns...basically its gg for them at that point. Sure i can run around and hope to survive...but still no chance. Also to add, you have only 1 bubble skill on you, the heal which you get from the first trial and thats it. No other skill bubbles spawn no nothing.
Didn't quite follow. You mean the tka-rik cave challenges when you enter there the first time?
At the beginning (1st round) you get 3 orbs - yellow and couple blues. They give you crystal barrier, jump device and speed boost. Then Sarn will appear and yellow floating orbs start to spawn you need to kill. The trick is to chain Sarn temporarily and kill the spawned mobs while he's chained. The orbs get harder each time. When you kill the last (probably 7th or so), the quest is done and Sarn vanishes. Energy regen is quite quick, that shouldn't be such a big problem like it is for mana users that run out of mana. I just did this quest today with one of my incarnations and at least for me I could use the crystal barrier over and over again. Otherwise my mana sucking Psi would have died because I was out of mana after 4th orb.
After Sarn you get another orb which gives you a powerful weapon and a mob appears inside a bubble. You have to run from the mob for 20 seconds, then his bubble will vanish and you fire the weapon instantly killing the mob. Done.
On 2nd round you need to survive for 3 minutes by collecting orbs that grants you different weapons and boosts. Easy enough. Just run 3 mins. Once again, you have crystal barrier you can use which heals, protects and removes all debuffs from you. I didn't need it in this quest though.
On 3rd round (last) you will have to kill spawning waves of mobs which becomes harder each time. Starting with 1 astral hound, then 2 and 3, then you get 2 hounds and 1 worm, then 1 hound and 2 worms and finally 1 hound, 1 worm and 1 winged demon. After killing them, you will see huge amount of demons appear at the edge and a yellow dragon appears in the middle. When all the demon masses reach you, you use the crystal barrier and the dragon god kills the demons for you. Done.
In all rounds I could use the crystal barrier more than once, if needed. So I don't know was it a glitch for me or have they made it so much easier after patch. That's why I wondered maden's post.
