I've come to the conclusion that creature summoning items are too op against the current AI intelligence. Not because of their powerlvl but because you can refill the item just my taking a nap so any hard encounter can be countered by summoning a wall of meat while you nuke everything from behind.. 

so far i found 7 items that summon monsters and im sure there is more..

 

I thought a couple possible solutions,

1)the first is making the items have limited uses before becoming useless like the Fireball necklease.

2)Other option is so this items only refill by resting in an INN, not in the wild.

3)You could need to pay an NPC to refill them or use the crafting system so it actually costs you resources (filling it with adra stones or soul residue and gold)

4)This items give you afflictions or some kind of negative effect when used.

5)Limiting them. You can only summon ONE item-based creature at a time, instead of one for each character at the same time.

 

 

I had the same issue with PoE1, there is just no reason not to use them..

 

 

Along with Empower and a dozen other things. Summons are there to cheese solo runs, they are complete overkill in a party situation.

Yes incredibly so. Don't use them or you ruin the game for yourself by making fights even easier than they already are.

I like the idea of using the existing crafting system. Makes it more consistent with other items.

Shh! Don't tell anyone. This was true already in PoE1.

I only ever used the Obsidian lamps, the ones that summon shades.

 

Cause the shades look cool as ****.

I mean, have you seen those dementor-looking mother****ers? 

I haven't used any summons in this game yet. Likely, because combat has not been too difficult (which is fine by me).

New idea: You could need to Empower the item to make a summon.
