Veno - Tanking astralwalker

Well, you can't pull astral, once you attack him, he stop moving.
So, try to wait until he is at a good spot so you pull 1 or 2, 3 max. Then kill them with your herc once they spawn. Good thing about this is that pets ignore defense bonus from level. I think that boss is hard for solo, good luck anyway b:victory

Edit: also to not lose aggro, 1 hit boss, 5 hits add, until the add dies.

Soloing it would be really hard. My Strategy involves 1 other character that can heal (Cleric or Wizzy).

-Have wizzy/cleric teleport over before you and run up the ramp/chain to the right.

-Teleport over, go right. Summon herc in front of the little ramp. Buff with magic and physical defense but don't bramble. run up the little ramp and chain as high as your range can heal.

-Have wizzy/cleric stand as far up the chain in heal range of you and keep you targeted.

When he spawns minions they will aggro to Herc (unbrambled). Your healing will aggro them to you. Wizzy/Cleric healing you will aggro them to wizzy/Cleric. Since wizzy/cleric is out of range they go yellow and run around like chickens without heads. (<3 love my wizzy husband)

If done properly the first 2 sets won't aggro to your herc. (the spawn of 1 and 2) they'll stay at their points of the graphical star. Once the 3rd set spawn though everyone aggros and it's incredibly fun to watch xD

Warning: Astral has random aggro. I have had another veno DDing with their pet and Astral suddenly killed me, for no apparent reason. This has only happened when I've had a second DD. So if you're out a barb and wanna herc it I suggest only Herc DD.... which takes foreeeeeeeeeeeeeevver

SORRY for WALL O TEXT
in advance

with niki's post is the correct spot however you do want the boss to be a exactly in front of that pilar before you teleport ove&send in the hurc once he is over to the boss you are healing him then buff hurc with all 3 buffs yes reflect to (note it no longer works on asteral however it does on the add's if you do tihs right) i catch the boss with hurc b4 i even buff hurc senidng him as soon as i summon spamminghealingthe whole time then buffingwhen he gets there then i move up to about where hurc is then continue healing a bit then move to the far side of the boss next to that pillar as seen in the pic and heal some more then hope up onto pillar heal a few times and run up to the top stop heal some then bring hurc to u for a split second and send him back in to attcking once he is about halfway through the boss because he tends to stop running just at the foot of the platform and turn and attack again. then once the first add on your right dspawns i believe its the fire one i send hurc right after it and stop hitting the boss i leave hurc hitting it and heal only once add is at 75% hp i send the hurc to the boss for 10 hits and then back to the add again till50% and repeat at 25% then send hurc back to the addinstead of letting it just blow up and ignoring it (it is extremely hard to kill) so that isnt why i send hurc to it instead it hits less hard phy dmg then its mag dmg hit so with asteral hitting and add hitting dmg is less and you wont risk the hurc being anywhere low on hp when the add goes (boom) then i am healing still till hurc is full again and walkto the bottom of the pillar (not getting off iot) put hurc on follow and then halt him at the base and put on attack again repeat withsecond add on the right after the2 adds are gone bring to pillar bottom again and just DD also tip try to stay away from the right side of that pillar and do not use massive genie aoe skills because it may aggro a add if the boss is not close enough hope that helps

Im not sure how venos solo him (for obvious reason lol) but i think at least part of squad strategy can be adapted
1) wait till astral moves close to back platform, then teleport, run to that platform, summon herc and grab boss with herc
2) move as far up the chain as you can to still be in heal range
that cuts the number of minions you have to deal with to 2, so big improvement here
rest may or may not be applicable:
3) i stay on a platform (not on a chain) because i want melees to be in bb range. still i have seen minion try to aggro on me and reset when he couldnt reach me
4) on back platform minions you get are toxin and fire, they hit very weak on arcanes, on my last run in 2-3 it was about 300 per hit so i told squad to just ignore them and focus on boss, in bb i tanked them without any problem (that is until someone aggroed 2 more ) you should be able to tank minions on pots i think, without bb they would hit for around 600-700 and not very fast so not a problem here
5) im not sure on that random aggro issue, dont think i ever saw astral hit anyone but tank, im certain he never aggroed on squishies crowded on platform, even though everyone but me was going all out with damage...

hope this helps a little b:pleased

i can solo it from any position tho.. the best one is far right side imo

i dont need any cleric/wiz help at all, just wait for the right moment when astral is near one of those chains then teleport, summon pet, buff only first 2 skill and never ever use bramble pet self buff.
send pet to atk then slightly go near boss and position herc as much as possible near border platform. after that use hold on pet and go on chain and heal, i just do 1 step 1 heal till im at max range. after that its just time, minions wil respawn, some will be avoided others will reset. even with full set on minions on pet i can still heal and do the job till the end.

edit:i never kill minions but if you start killing them your pet might die not because of more damage but some minions explodes before death

long as hes close to a pillar you can run max range on a chain... your fine until the 2nd wave of mobs comes but after the third comes you might wanna spam heals, dont put reflect on your herc so that the mobs keep resetting, your herc will take less damage that way and its alot safer ASTRAL AGRO RESETS AT 3.6m 2.4m AND 1.2m just bramble hood around those times to be safe or stop the healing for a few seconds if your herc is high lvl i do this all the time and i almost never fail b:laugh

if your going to kill the adds give your herc a few seconds to agro astral or you will out agro him with your heals and get a nice slap across the face
