Invinciranger in snowmen's lair (farm NM, HM, chestrun)

tried this and I have a bit of a problem...after saccing for the 15%dp (38 hp), I cast the bonds with a staff equipped, but I'm only able to cast watchful healing and protective bond, because if I cast balthazar's too, when I switch back to my bow, I lose one of the bonds. So what I've been doing is cast WH, PB, Stormchaser, Feel No Pain, and IAU, then switch to my bow quickly..get a few hits to bring energy back up and then cast Balthazar's. Kind of a hassle to do really. The ranger's inherent energy regen rate must be too slow to maintain three enchantments? Or, am I doing something horribly wrong? Once I get the ench up I can usually finish the first two waves in NM/HM, but something seems wrong as it appears Bogus is casting all three ench prior to engaging (vid is sped-up so I can't be 100% on that)....nice vid though, btw Bogus.

BogusDude - im glad you said about AoS as ive done that myself a few times till i realised you gain no xp in the whole dungeon - very sneaky anet :P

GW Poster - im a bit lost as ive just watched BogusDudes video and he isnt using enchants - he`s using r/a and i assume its different from the ops build (r/mo im guessing from the skills you said ) and that may be whats causing you the problems

Obviously cos you loose a pip of regen when you cast your bonds you should be casting one bond at a time, regen fully, next bond, regen fully, next bond. I then switched to my bow right before aggro because i was using a zealous bow and switching beforehand would have meant negative regen. I was using my staff because my other non zealous bows were in storage while i farmed and my equipment bag is full with armour sets. Some people prefer 20/20 with Barrage my personal preference is almost always to go with a zealous^^

Also you want to try not to aggro the glimmering snowman who'll blind you and take him out seperately. You'll notice i aggoed him and tried to pull back and loose him because he blinded me

yeah, thanks bogus..I figured it out and it works fine..I don't even bother with the staff/switching- I just use a 20/20 bow, it takes a few seconds longer to wait for recharge after casting bonds, but only need enough energy to cast stormchaser and FNP, the first few hits will supply more than enough energy to cast the rest
