Sand Swept Tomb Help (lv 38 Assassin)

This is the first time I posted on this forum and I'm requesting y'all's help on how to beat sand swept tomb as a lv 38 assassin who has mostly shadestepper skills and sometimes clear content with a warrior friend.

The part where I always die is that room where you have to kill a swarm of mobs to get 30 tokens. There are a few problems:
1. it separates you and your party members, and the swarm of mobs is pretty hard to take on solo imo
2. Even when I finish collecting 30 tokens, it requires me to put in each token ONE BY ONE, and I often get killed while trying to put in the tokens

In addition to general advice on how to deal with the dungeon, I also need help on picking equipment
1. Should I bring Phantom Blade or Stabsand? the first one gives more spell damage % and mana regen but the second one has explosion and life steal + dex buff
2. For leggings should I wear Panorama or Philosopher? The first one buffs all types of damage + all types of defense, while the second one gives more health, life regen, and defense while tanking damage

anyways any and all help is appreciated haha I'm trying really hard to get the hashr claw since I heard it's really good.

 

if you are shadestepper or trickster, once you get 30 tokens, click the thing then vanish, they automatically go and you can run around while wating.
phantom blade seems to be better, but also remember once you hit combat 39, hashrs claw is like the best weapon until locrian. For leggings, probably go for more tanky ones if you are losing health.

 

Imma introduce you to Adventure's set .-.
Pretty cheap on tm.
Also it's not always 30 tokens (pretty sure)
There's a chance it's like 1 token with waves?

 

What are you wearing to be struggling with that? A majority of armor at that level range is pretty good, so do be sure you’re not wearing level 10 gear

 

Thanks! I didn't knew it would just automatically put it in after clicking once lol I'll try that later

Yes I'm trying to get the adventures set right now since before I traded them to my friend who wanted them. But if I remember correctly I thought the adventurers set don't really give a lot of hp?
also yeah I've encountered the one token one but died anyways lol

Isn't that the entire point of those rooms

You just need to click once for the tokens to start being loaded into the door

 

It gives you enough damage to be chilling

 

I suppose so, but also the annoying part haha

Yeah I didn't know that, I'll try that again later
