Warrior/Knight Help Which Build Is Preferrable?

Ok, I've got a fiasco to sort out here, which build works better for Collapse? Yeah, I know there is probably a better build and Collapse isn't as good as other spears but let's just put that aside and figure out which is better. Besides, who doesn't like explosions(honestly Collapse could just be named Boomstick instead)? I have 2 builds that I think aren't too bad but if ya know of a better one, post it bellow.

I have one that uses the entire Morph set. The pros of this on is it has health regen, mana regen, mana steal, and 45 extra skill points. The cons is it doesn't have too much health and it's elemental defenses aren't as good as the next one. This build might be better as it can be spell spammed a lot more due to the reduced mana usage from morph and intelligence, mana steal, and mana regen.

The other one is a bit harder to get as it requires going through Legendary Island and you would need 2 mythics instead of 1. The pros of this one is that it does more damage overall spellwise, is more tanky, and has a lot more health. The cons, it has less extra skill points and spells cost basically twice as much as the previous one.

Any help would be appreciated and have a nice day.

 

The first one is definitely better, but most builders don't call this a build usually as it is just a premade set (which is not very loved among builders since it is said to hinder new builders with developing familiarity with the items they should use and getting creative with their builds).
