Guild Wars 2

Engi looking to run HoTW for the first time, looking for equipment/build/sigil tips and tricks.
Suggestions please?
Found lots of info on the dungeon itself, but not much on the desired build and armor stats.

Thanks!

Assassin/ berserker mix ( aim for 63% crit chance), 6/6/0/0/2 with all the modifiers available, grenades/ elixir gun/ flame thrower ( you can swap either eg or ft for a team utility)

I’ve found that if you need more dodges you can go 6/6/0/2/0 with the swiftness on crit in the precision line and then vigor when having swiftness in the 2nd to the last line. Slightly lower dps but it makes the troll a lot easier along with the butcher in p1.

General: For the harder hitting groups of mobs that you’re not skipping, bring bomb kit for smoke bomb, and throw a flash grenade after the second pulse or so if necessary. Consider using Supply Crate to stun the more deadly groups like the wolves in p1/3 or the groups of berserker’s in p2/3.

P1: Remember to cleanse crippled off of others when skpping past the hunters before troll if you’re not stealthing past. If your group does not have a thief or mesmer, you can retrait slightly and act as a defiance stripper and interruptor at troll to keep his leap interrupted. Remember to dodge any stun projectiles he aims at you if possible. For Aldus, you can help with reflect chaining with Toss Elixir U to block his autoattack and lessen pressure on your team. After Aldus, you can provide stealth for your team for an easier skip through the trapped hallway. For Ginva, remember that you can easily kill yourself from retaliation if you use grenade or flamethrower autattacks, so either keep the retal totem down as much as possible, or switch to bomb kit when it’s up. His projectile attack can be reflected, but just that won’t allow you to stay in melee range all the time if you have aggro, because his swing auto does so much damage. Remember that his melee auto also has a ridiculously large arc, and if you’re not directly behind him or out of range you’re going to get hit. When he goes into whirling, you should get up close to him (just out of range of his whirling) and use bomb auto for damage.

P2: Remember to blind trash mobs up to Torn Fur and after Balgren. At Balgren, remember that you can dodge his fear by dodging back during its chargeup animation and moving back afterwards, as it has a relatively short range. You can provide stealth to skip the ice fish after Andal (stealth just prior to entering the water). For Wollam, use traited bomb kit as your main damage source. Grenades suck underwater and will hardly hit unless you’re inside the enemies model, so if you must range use elixir gun autoattack. Remember to use speargun’s hardhitting skills whenever possible at close range.

P3: For Svanigandr, be sure to dodge his leap. Max melee if possible, but stay mid range with grenades if not. There are 2 ice bombs in the room you can clear quickly with grenades prior to starting the fight. You can provide stealth for skipping the elites after killing him. Remember to blind the elites before and at Fimbul. If you want some laughs, bring Toss Elixir U for him, as his 3 knockback circles attack can actually be reflected. You can provide stealth for skipping the jellies and whatnot underwater before Sorge. Start your stealth rotation standing on top of the barrel floating next to the stairs. For Sorge, try to blind the adds he summons (esp the jellies) to mitigate damage. Remember that you can rally off them if necessary.
