Hi just wanna ask some questions here..... Q1. Im Lv35 in Silver mode Orc Realm now and yeah BT is doing some good damage I usually kill a pack in 1 to 2 BT waves but I feel really squishy a few mobs can make my HP drop so fast I usually die in few hits sometimes even before my BT kills them. EG: CHamps + few mobs. I always get hit during casting after I rounded them up so would appreciate any advise on this matter. My skills distribution atm is 35 Pyro Focus , 35 Pyro Lore, 20ish Concentration, 9 points in Delphic Focus and 1 point in Ancient Magic/Armor lore. Is it normal for a HE to die this easily? Q2. I have ate like 20ish Incandescent Skin runes and 14 Grand Invigoration runes and I've just reached 1.9sec BT mark(Mounted) still working my way to meet the 1.1 - 1.5 sec per BT target. My BT is at Lv7 right now (1 from rune, 6 from equipments) but im confused about when is the right time for me to start eating BT runes or should I keep it at Lv1 all the way and raise the level with gears? It seems to me that eating BT runes really hurts my regen time badly now (+0.3sec per level from rune). Also, by trying to adjust the regen time for BT at 1.1s - 1.5s do u mean these figures with +skill gears on or off? Q3. I don quite understand the skill mastery thingy.... Is it more productive to stop my Pyro Focus/Lore and concentration skills at 75 after getting these 3 masteries and continue to complete all other masteries before I come back to invest points in them again? It seems to take ages to get the other skills to mastery if I only spend 2 points per level in them. Thats about all I have to ask for now and thanks in advance for any replies.
