Getting hit by adamantine or valpurium golems is already playing with fire regardless of armor, they are both capable of OHKOs without warning. I don't think psypher golems are any worse by that regard. One time I distinctly recall getting one-shot was through valpurium plate +6 or so, while whacking a valpurium golem with a valpurium head of an enner right after killing Elpuri. Sudden critical kick to the chest sent HP to negatives. Never messed with high end golems afterwards. :x
I will agree though with psypher likely being too strong for equipment, if it's a full third stronger than valpurium. Special effects would be a cool trade-off for a nerf.
Teleportation scrolls are actually pretty handy to have out in your inventory. Yeah, they do burn occasionally and take time to read out, but they do have one thing going for them wands don't. Reading doesn't require functional arms unlike wands, so they work as a last resort escape if both your arms are disabled or cut off.
Wands of necromancy though, just why. I've never found situation where having a weak zombie pet would be useful. Or do they nowadays create zombies according to the type of corpse? Something like a zombie orc general could be a decent temporary ally if equipped.
If by no weapons you mean uncategorized weapons are allowed, then sure. IIRC I completed an Elpuri run wielding gauntlets years back and seem to recall a knight / high priest win by someone as well, though don't quote me on that last one.
