Equivalent "power" boost of Fungi but for int casters?

[1asdfasdf1]

Recently got a fungi (my first one ever!) and as much as I love wearing it on a lowbie shammy, I'm wondering: What is an equivalently powerful item for int casters? I don't mean specifically for regen. I mean anything that is roughly 55k and OP for newbies / lowbies.

Special case: Clerics can wear fungi but don't get anywhere near the value from it as melee and shammies do. (At least not without manastone)
