Good hope is a nice to have clickie if you have an epic mask of comedy laying around, it's beaten by greater heroism but you still get a +2 damage and you get a 3 charges per rest.
A Jack Jibber blade is pretty much a MUST HAVE item on every toon.

https://ddowiki.com/page/Item:MagestarClickies for deathward, shield, displacement. Scrolls to raise party members and heal scrolls too. You don't heal with scrolls but they are useful to completely remove ability damage. If you play on reaper, even on R1, the lesser restoration pots will only cure 1 ability point per pot. Invisibility too is a nice to have even if I haven't had a reason to use it in the last years but you never know. Other clickies/pots depending on your class/resources
I'm really fond of fire shield on both versions as you can cut in half damage from fire and cold. In theory, pots of protection from evil should be good but I've noticed that in recent content most things can simply bypass it (immunity to mental compulsions my fucking ass), don't ask me what monster though, I simply remember that I had the buff on and still got CCed when I shouldn't have been. Can't think of anything else right now, I'm sure someone else will post more stuff
Oh yeah, a towel. Never leave house without a towel.
