Ice wall - which spells pierce the wall?

Hey, I was messing around today with my wander, trying out all kinds of funky utility spells to use on a totem until I tried out ice wall. Now, on a wander it is far from efficient, because wand hits & power siphon hits are stopped by the wall, but on a caster build with say... firestorm I could definetily see ice wall totem helping out way more than the more commonly used skeleten totem would (assuming you aren't going for dual totem build to behin with, in which case you obviously use damage spells on the totem insead.).

Now I'm curious if anyone has already tested the wall out and already know which spells go trough it. I am going to assume all projectile spells get blocked by it, but it doesn't stop you from for example casting firestorm over the wall. Anything else funky like that? :D

I've used frost wall on my cold crit shadow. you can cast freezing pulse and ice spear through it. Im not sure about other projectile spells like fireball, but i guess it would pass through if ice spear does.

I've tried it on a totem also. its quite funny to see walls constantly spammed at anything coming near it. Compaired to a totem with skeles on it , it works pretty similiar. The skeles are better i think against groups of ranged mobs, since they tend to aim for you more if your just popping walls up, if its skeles they target them more.

I just got this gem as a quest reward. I don't understand the point of it at all. I am so disappointed that I didn't get discharge instead. I pop a wall for a good chunk of mana, and it does next to no damage, mobs simply walk around it in less than half a second. Ok, so I can shoot ice spear through it and they have to walk around it whoopty doo. If I had used a minion spell instead they would have distracted the enemy more than half a second....

It lists damage for enemies trapped underneath of it, but it seems that doesn't happen. They simply get pushed back if you are mousing over them when you cast it.

Am I missing something here?

I don't think damage is the point looking at its wiki listing. It will get longer as it levels so eventually it will take some time for something to go around it. Add in indoor areas and it can cut things off in terms of pathways. Added quality adds to the length as well.

Frost Wall info

Quality on Ice Wall is insane.
20 quality gives 15 length, where the normal is 20-30.
Probably the biggest quality bonus in the game right now.
